Re: EMC Directive + UK Regulations - take 2

Bill, 

This is an intriguing question. According to the legislative record publicly
available, this change of text was part of what the Commission put into the
revision mill and it was not challenged by Parliament or Council. Ref
http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=COM:2002:0759:FIN:EN:PDF
http://eur-lex.europa.eu/LexUriServ/Le
UriServ.do?uri=COM:2002:0759:FIN:EN:PDF  

There may have been a preperatory study that prompted the change, or it may
have occured unilaterally by the Commission person who had the dossier at the
time. The above linked document uses the term end user several times and it
may give you some idea what they were on about. 

You may well be able to contact the Commission on this point and get some
satisfaction. If you do, be sure to share ;-) 

Cheers,

 The phrase was introduced into the new EMC Directive 2004/108/EC,

It's not possible to tell from your messages. It depends on your 
apparent concept that an end-user may not exist.  Well, if a product is 
never used, obviously it doesn't matter whether the Directive applies or 
not.

So I think you have to tell us what you mean by the concept of product 
that has no end user.

When the solenoid is de-energized, isn't there a large and fast voltage
generated? When a solenoid manufacturer puts a diode across the coil to
limit the voltage, doesn't the large current flowing through the diode
and coil create a spectral distribution of energy? Perhaps the Directive
ignores the short duration burst, but I don't think you can call a

I seem to recall that one of the earliest EMI problems was one that came from
solenoids (well a version of one that held the core stationary and used the
coil discharge). Resistor wire and resistor plugs reduced the problems to
acceptable levels in cars.  If you can find any of these parts without the
resistance, substitute them into your car and listen to what happens.

So how anyone can say solenoids are benign from an EMC standpoint is 
beyond me.

Solenoids are normally included in equipment (or systems), so are 
covered by the EMC assessment and testing of the equipment (or system).

While I don't necessarily want to defend ERA, it is a large organization 
that doe a huge amount of complex EMC work. If they had no evidence of 
EMC issues with solenoids, I suppose it is a very rare occurrence.

When the solenoid is de-energized, isn't there a large and fast voltage
generated? When a solenoid manufacturer puts a diode across the coil to
limit the voltage, doesn't the large current flowing through the diode
and coil create a spectral distribution of energy? Perhaps the Directive
ignores the short duration burst, but I don't think you can call a
solenoid coil completely benign.

It happened that each time the solenoid was de-energised, our

This is not a lack of 'EMC benignity' of the solenoid as a component. 
The Directive applies to the product that includes the solenoid. That 
has to meet electric field emission limits, which should protect your 
controller, IF its immunity is sufficient.

They would appear to be as benign as an induction motor, since both 
produce only magnetic fields. The important point is which standard(s) 
the DoC cites, so please tell us.

A solenoid valve does raise safety issues, and would therefore need a 
DoC, but, if I recall correctly, the German national committee has drawn

I would have thought that the EMC performance of the solenoid would depend

15.32 goes on to say that under the test conditions of (a)(1), the emissions
shall not exceed the limit by more than 6db. I guess the presumption is that a
typical enclosure cover will provide at least 6dB of additional attenuation.

The (United States) Federal Communications Commission's (FCC's) approach

described in Sections 15.32 and 15.102 of FCC 47 CFR Part 15, at
   http://www.fcc.gov/oet/info/rules/part15/PART15_07-10-08.pdf

Paragraph 15.32(a)(1) says:
Section 15.32 Test procedures for CPU boards and computer power 
 supplies.

 Power supplies and CPU boards used with personal computers and for 
which separate authorizations are required to be obtained shall be 
tested as follows:

  (a) CPU boards shall be tested as follows:

  (1) Testing for radiated emissions shall be performed with the CPU 
  board installed in a typical enclosure but with the 
  enclosure's cover removed so that the internal circuitry is 
  exposed at the top and on at least two sides.  ...

The rest of this section goes into much more detail about the testing
requirements, and an alternative test configuration.

Paragraph 15.102(a) says:
Section 15.102 CPU boards and power supplies used in personal

 (a) Authorized CPU boards and power supplies that are sold as separate 
 components shall be supplied with complete installation 
 instructions. These instructions shall specify all of the 
 installation procedures that must be followed to ensure compliance 
 with the standards, including, if necessary, the type of enclosure, 
 e.g., a metal enclosure, proper grounding techniques, the use of 
 shielded cables, the addition of any needed components, and any 
 necessary modifications to additional components.

That is widely understood, but the volume of DIY computers is small and 
any actual problem can in theory be dealt with on an ad-hoc basis (as 
for usage in N America of Class A products in homes).

Unless the manufacturer is able now to produce operational motherboards 
that pass emission tests without enclosure !

definition:... end-user means any natural person (e.g. consumer) or legal

Devil's Advocate and EMC amateur I am.

For both personal use and for test bench automation at the factory, the MB
is chosen with attention to EMC emissions and immunity. So this stuff can
be considered important to both residential and industrial end-users. 

It is not unreasonable for the non-engineer end user to expect that the mb
will not require installation in a steel vault with a beryllium gasket
around the cover and not be subject to total destruction from a minor ESD
event.

apparatus by the end user do fall under the scope of the EMC Directive.

Does a PC motherboard by itself fall under the scope of the EMC Directive?
Article 2, paragraph 2(a) states that for the purposes of the Directive,
the following is deemed an apparatus:  components or sub-assemblies
intended for incorporation into an apparatus by the end user, which are
liable to generate electromagnetic disturbance, or the performance of which
is liabile to be affected by such disturbance.

Therefore, I think a PC motherboard (or any other commercially available PC
board) falls under the Directive.  Am I correct?

Hi Mark,

 

If you ship the adapter (deemed active or not) with your device then the
accountability of shipping a compliant device is your responsibility and will
require you to test at system level to meet the requirements of 89/336. It
goes back to the ole CE + CE = ???

I am not sure how I ended up caring so much for power adapters recently, but
they just will not go away. 

 

Would you consider linear power adapter : 240V to 12V/1.5A consists of the
transformer, bridge rectifier and capacitor to be EM active device? If it is
not active, will it be safe to assume what it will be excluded from 89/336
directive based on EU guidelines?

Mark,

The switching spikes of a full wave bridge / capacitor arrangement can
be found to extend above 1GHz if the design is poor.

In no way is it a passive device!

RE: EMC Directive requirements for LINEAR power adapter

2007-03-21 Thread emc-p...@ieee.org
Mark,
 
I would say not. Your adapter includes diodes, which are a form of switching
device and will cause interference of some description to an extent that
depends on the speed of the diodes. An EM passive device would be something
like a filament lamp or an electric heater (providing it doesn't have a
thermostat); i.e. items that draw a constant current at supply frequency. You
are fortunate that you are considering a low power device, otherwise you would
definitely be having to consider harmonic emissions; a simple
rectifier/capacitor configuration generates those very well.
 
As a technicality, forget 89/336/EC. It was repealed and replaced by
2004/108/EC.

from 89/336 directive based on EU guidelines?

No, because it emits mains harmonic currents and, depending on the type 
of diode in the rectifier, perhaps emits conducted noise above 150 kHz. 
However, it's certain that its mains harmonic emissions are subject to 
no limits according to IEC/EN 61000-3-2 (lower bound for the application 
of limits is 75 W active input power), and 99.99% certain that it meets 
the limits for conducted emissions above 150 kHz.

So, although it's not *excluded*, it can safely be claimed to meet the 
essential requirements of the EMC Directive without testing.

Note that 89/336 is the old Directive, to be superseded for some 
purposes on 20 July this year and wholly on 20 July 2009 by the new 
Directive.

Re: EMC Directive - indicating restrictions of use

2007-03-08 Thread emc-p...@ieee.org
 1. What's the sensible and practical middle ground ?

I believe that  this information should be included in a printed user manual. I 
would also
include this warning on the outside of the enclosure, for example: on the 
rating label.

My 2 cents.

  AM
   

   




Article 9 para 4 in EMC Directive 2004/108/EC reads as follows …..


Apparatus for which compliance with the protection requirements is not ensured 
in residential
areas shall be accompanied by a clear indication of this restriction of use, 
where appropriate
also on the packaging.


One way of addressing this requirement is to include information on this 
restriction in the
instructions for use that are part of the user guide on a CD shipped with the 
product (in this
case a PC or PC accessory). The other extreme is a large printed warning on the 
outside of the
shipping carton indicating not suitable for use in a residential environment, 
together with a
hard copy warning notice included in the box.


1. What's the sensible and practical middle ground ?


2. What do they really mean by the words 'clear indication' and in particular ' 
where
appropriate' ?

Re: EMC Directive interpretation

2004-07-18 Thread owner-emc-p...@listserv.ieee.org
http://www.ieee-pses.org/symposium
  http://www.emc2004.org/


I read in !emc-pstc that =?iso-8859-2?Q?Konrad_Stefa=F1ski?=
kstef...@poczta.onet.pl wrote (in 002d01c46bfd$50d39d00$0301a8c0@konr
ad) about 'EMC Directive interpretation' on Sat, 17 Jul 2004:

I would like to ask you how to obtain conformity with EMC Directive to
the following product: Tension-converter used in tension-meters or
weighting devices.

There is a separate Directive for weighing machines, and your product
may be within its scope.

It is only resistive device, It consist only
resistors which could change resistance with tension changes. These
resistors are serially connected. It has no other electronic and
electric parts in its construction. This converter could only work with
other device, but it may be selled as stand alone device.

So my questions:
1. Does this device (converter) lay under scope of EMC Directive?

Yes, is the simple answer. You might be able to make a case that is
doesn't, but it would be difficult, and there would be a permanent risk
that your case would be successfully challenged.

2. If YES, is this necessary to do tests in accordance with EMC
harmonized standards to show conformity with directive ? I think that
this device meets EMC Directive requirements without any tests (only
resistive character).

You probably don't need to do any tests in order to justify the
Declaration of Conformity. But it would be helpful commercially if you
could claim, on the basis of tests, that it did not affect the EMC
characteristics of whatever it has to be connected to in order to use
it. The appropriate tests are probably radiated emissions, ESD and
radiated immunity.

3. If NOT, is this device a EM-passive component?

'Passive' is a misleading word. Your device is passive, but it may not
be 'benign', that is, it may affect the EMC characteristics of whatever
it is connected to.

The above points probably apply to ANY device that has no active
components and is connected to something else in order to work, if it is
placed on the open market by itself.

RE: EMC Directive

2002-08-22 Thread Gert Gremmen

Hi Joe

It's much more simple then that.
The EMC directive references harmonized Standards list.
The list of harmonized standards is listed
in the Official Journal = LAW.
The date of publication of the list is the date
that the standard may be used for the first time.
The list mentiones dates of withdrawal for older standards = LAW
Logic thinking does the rest.

John,

Article 7 in the Directive discusses using national standards to meet the
protection requirements of the Directive.  The Directive does not go into
detail on DOW's of the standards.  Take a look at the Guide to the
implementation of directives based on the New Approach and the Global
Approach  Section 4.5 discusses revisions to the standards. It states
...the relevant European standard organisation lays down the date of
publication at national level of the revised harmonised standard, and the
date of withdrawal of the old standard.   The transitional period is
normally the time period between these two dates.  During this transitional
period, both harmonised standards give presumption of conformity, provided
that the conditions for this are met.  After this transitional period, only
the revised harmonised standard gives a presumption of conformity.

These guidelines can be downloaded from the following site.

I know this has come up before, but I need to quote chapter and verse.

In a conversation with an acquaintance of mine, the EMC Directive became a
topic with
DoW and use of superceded standards for presumption of conformity becoming
a
contentious area.
I maintain the following understanding:

A product is evaluated to standard A. At some point standard a can no
longer
be used for
presumption of conformity (DoW) and standard B must be used. Therefore if a
product is
still being manufactured for sale after the DoW of standard A, then the
product must
be re-evaluated according to the new standard B. (An exemption being those
items
returned for repair and not modified/updated/upgraded).
If the product was no longer produced and placed on the market after the
DoW
then
there is no issue.

My acquaintance notes that if the product was tested to standard A, as long
as it
has not been 'updated, modified, or changed in anyway' since the initial
compliance
test, it can still be manufactured and placed on the market after the DoW
without
re-test.

I believe that my understanding is the correct one. I tried to locate it in
the EMC
Directive itself but I can't seem to find it. Am I incorrect?

Your understanding is correct. The 'dow' should be the 'docopocotss' -
'date of cessation of presumption of conformity of the superseded
standard', but even Brussels jibbed at that. 

The relevant text is not in the Directive, because it applies generally,
not just to EMC. I don't know which publicly-available document explains
the meanings of 'doa', 'dop' and 'dow', because I have them only in
committee papers.

RE: EMC Directive

2002-08-21 Thread Gert Gremmen

Partially Wrong.

The only reference you will have to use in Europe
with the Compliance matters and standards is the
published list of Harmonized Standards .
Dates  (DoW) printed in the standard itself may
or may not be the same but are irrelevant in CE Europe.
The reason for this is that standards are private documents
created by private organisations. The EMC directive is law
as well as the list of harmonised standards.
This list  is available at many sources .
The list includes dates on which any standard
is superseded by it' successor.
The product will have to comply with the new standard
regardless of any modification.
If you or any client does not agree, the route 10.2 of
the technical construction file may be used.
A NB will review your design and measures that have
been taken to comply with essential requirements.
Often this will lead to the same result as using the new standard,
especially if new phenomenae are to be tested in the revised
standard which were not in the earlier.
No escape route though, but may be used if injustice
would have been done to your product.

The EMC directive directly points to this list of
harmonized standards, and that should justify that
your opinion is right.

I know this has come up before, but I need to quote chapter and verse.

In a conversation with an acquaintance of mine, the EMC Directive became a
topic with
DoW and use of superceded standards for presumption of conformity becoming a
contentious area.
I maintain the following understanding:

A product is evaluated to standard A. At some point standard a can no longer
be used for
presumption of conformity (DoW) and standard B must be used. Therefore if a
product is
still being manufactured for sale after the DoW of standard A, then the
product must
be re-evaluated according to the new standard B. (An exemption being those
items
returned for repair and not modified/updated/upgraded).
If the product was no longer produced and placed on the market after the DoW
then
there is no issue.

My acquaintance notes that if the product was tested to standard A, as long
as it
has not been 'updated, modified, or changed in anyway' since the initial
compliance
test, it can still be manufactured and placed on the market after the DoW
without
re-test.

I believe that my understanding is the correct one. I tried to locate it in
the EMC
Directive itself but I can't seem to find it. Am I incorrect?

RE: EMC Directive/Repaired Apparatus

2002-07-22 Thread POWELL, DOUG

Joe,

I've given this topic a fair amount of thought.  I believe the intent of the
new approach directives is only for equipment being put into service for the
first time.  My understanding is if the repair is only a repair and not an
upgrade of any kind, then you may simply put it back into service at the
same place where it was originally placed into service.

There are a number of documents that give good guidance at:

http://europa.eu.int/comm/enterprise/newapproach/index.htm

There are a number of documents linked to this page and I suggest a full
reading before deciding a course of action.  I got the most useful
information at:

 
http://europa.eu.int/comm/enterprise/newapproach/legislation/guide/legislati
on.htm

This is a guide to the implementation of the new approach directives and
there is a single PDF version near the top of the page.  In this guide I
found several items of interest plus a fairly good clarification of exactly
what is placing on the Community market (or put into service) for the
first time.  This would seem to exclude repair, refurbishment or renovation
of products.  The implications are many and here are a few that come to
mind,

1) I believe products which have been repaired without changing the original
performance, purpose or type, are not subject to further assessment.

2) I also understand that if you are installing any sort of upgrade to the
product which was made available after the applicable directive came into
force, then the entire product needs to be assessed to current requirements.

3) I do not believe you or the company doing the repair are allowed to keep
an inventory of refurbished service spares on hand as the guidance document
seems to indicate that the original (serialized) unit must remain where it
was first put into service (i.e. no stock piling).

4) Exactly how one provides markings and a declaration for this situation, I
cannot say ...

5) Applicable product directives take precedence over provisions set out in
this guide.  For example, if you are using products to the Medical Equipment
Directive, then you should be familiar with discussion it has on repair and
refurbishment.

Regards,

-doug

The following scenario is in regards to the EMC Directive.

We are a manufacturer located in the US.  We have various products that

We need to repair some of these products.  The repairs will not modify the

Questions:

1.   Following the repairs, do we need to meet the requirements of the

Hopefully someone has had some experience with this issue.

RE: EMC Directive

2000-05-05 Thread David_Sterner

 Be careful of declarations that include a specific model manufactured 
 by another company.  Without engineering control or intercompany 
 agreements the other product could change without notice, technically 
 negating your declaration.
 
 Nothing prevents the competent body from insisting on a cooperative 
 agreement between both companies to assure future compliance.
 
 Is this related to your earlier question about an UPS?

Assume a product requires the use of an external device in order to comply 
with a particular immunity test. Assume that the product is marketed without

the external device and the device is readily available in the EU member 
states. Is it acceptable to create a TCF for the particular essential

RE: EMC Directive revisions

2000-04-03 Thread James, Chris



Hoping this reaches the right eyes. Our comments on the document:
 
 
1. In many places, the English is not idiomatic and lays stress
inappropriately, often by incorrect use of the negative or of does. For
instance this phenomenon needs not to be considered means it is compulsory
not to consider it! Sometimes this doesn't matter; sometimes it would have
legal significance. If the English text is to carry legal weight, it should
be edited by a native English speaker to ensure that it does not convey the
wrong meaning; the same applies of course to all the other languages.
 
2. In annex II section C.1 concerning documentation accompanying a product,
there is the requirement that documents (presumably all of them, including
instruction manuals, declarations of conformity etc. etc.) have to be
available in one of the official languages of the member state where the
apparatus is to be taken into service ... I understand the desirability of
this for consumer goods, where it is generally followed today, but for
professional equipment I think it is unnecessarily onerous. A manufacturer
such as Dolby might sell only one or two samples per year of an apparatus
into say Finland or Portugal, and to have to translate and print multipage
documents into those languages would be uneconomic.
 
3. Article 5 contains a section that states: Member States shall not impede
for reasons relating to electromagnetic compatibility the placing on the
market and/or the taking into service for its intended use of equipment
conforming to this directive. As you are well aware, states and smaller
administrative areas such as cities are currently impeding installation of
equipment that conforms to the present Emc and low voltage directives,
despite CE marking and accompanying declarations of conformity . I suggest
that this clause should be strengthened to make clear that it applies not
only to national governments but to others as well.

Now I am really confused!! As I understand it the EMC Directive was never
intended to
INSTRUCT folks what tests to run or indeed what levels etc..to demonstrate
compliance.
 
Indeed one of the statements from the SLIM was the Directive per se was just
fine
and that the standards etc were the real problem area.
 
 Are these messages referring to the Guidelines in meeting the EMC
Directive?
 
Has the Directive really changed?

Ed, Richard, and everyone 

Following discussions in the SLIM working group, the Commission has 
now 
produced a draft of the revised EMC Directive.  This is a complete 
rewrite, 
not an amendment.  The major change is removal of the requirement 
for fixed 
installations to be assessed and CE marked prior to taking into 
service, but 
the possibility for investigation by enforcement authorities, should

interference be caused, remains.  The distinction between systems 
which 
continue to require CE marking, and fixed installations is unclear

at 
present. 

It is expected that the draft will undergo further development and 
changes 
at SLIM working group meetings during this year before a draft is 
published

I will be presenting a paper in one of the poster sessions at the

The basic protection requirements of the EMC directive state in effect that

operated.

An analysis of potential EM threats to an EUT and potential victims of the
EUT's emissions, when presented to the competent body in the TCF, can
result in  cases being made for using hand-held radios for RF immunity
testing, radiated emissions testing outside the building housing the EUT

and using current probes to measure line conducted RF emissions.

 I would like to compile thoughts and techniques that members of this group 
 use to perform in situ tests on large industrial apparatus. 
  Considerations I have typically encountered  include:
 
 Current draw in excess of available LISN capacity.  Use CISPR voltage probe
 Current draw in excess of available EFT  surge coupling network capacity. 
 EFT, use 33nF cap.  Surge,?
 3 or 10m EUT to antenna distance not achievable and/or high ambients.
 Lab type radiated immunity not practical due to interference potential.
 Large equipments requiring multiple antenna locations or search and 
 optimize considerations for radiated emissions.
 
 I am especially interested in potential alternate techniques for radiated 
 immunity.  Potential solutions may include ad hoc testing using actual 
 transmitters, eg cell phones, VHF, etc.  Testing at discrete frequencies of 
 known public broadcast bands.  Extended frequency conducted immunity 
 testing.
 
 If you have thoughts or other considerations, please respond to the group. 
  As US labs are granted CAB status, consensus on these, and other issues 
 will be helpful.

Re: EMC Directive and Small DC motors

1998-04-08 Thread Georg M. Dancau
I agree with Robert, that you generally have to test your product.
Especially because
conducted disturbancies on the power supply lines could induce
disturbancies on
other signal and power supply lines in a system. Since one can expect
only conducted emissions you only had to do this test ( I assume you
have no electronics in your
product). The costs for such a test should be less than 800$.

George

 source of the problems you had, they should go away. With regard to
 testing the new vendor, you are obligated to demonstrate compliance of

 the new motor. If you did not already follow the TCF route, it may be
 appropriate for you to consider it for these pumps. In that way, you

 Greetings,

 We manufacturer a small line of vacuum pumps that use very small (1/16

 hp) 12, 6 and 4 VDC motors. Just a DC motor and a pump. We have had
 some EMC testing performed to the EN 55014 and EN 55104 standards
 where there was some high conducted emissions that required a .1 uf
 capacitor across the positive and negative terminals. But I believe
 this is more of an issue of the power supply source, and lead lengths
 than the motor.

 These items are considered components because they need a power supply

 to operate. However, they could use battery power, but I assume that
 there would not be an emission problem in this mode.

 We now have another source for motors, and I have been asked to
 retest. I am very reluctant to spend thousands of dollars on testing,
 when I personally do not understand the benefit or risk. Of course the

 test house highly recommends additional testing. So I come seeking
 some advice or alternatives. Here are some of my thoughts:

 Since this is a component, could we just assign a declaration of
 incorporation?

 Are there any reasonable limits to what should be tested, as far as
 power/frequency/application in the directives?

 Is there a justifiable reason to test this product?

 Thank you for your consideration, any thoughts would be appreciated.

We now have another source for motors, and I have been asked to
retest. I am very reluctant to spend thousands of dollars on testing,
when I personally do not understand the benefit or risk. Of course the
test house highly recommends additional testing. So I come seeking
some advice or alternatives. Here are some of my thoughts:

Since this is a component, could we just assign a declaration of
incorporation?

Are there any reasonable limits to what should be tested, as far as
power/frequency/application in the directives?

Is there a justifiable reason to test this product?


Thank you for your consideration, any thoughts would be appreciated.

Actually, the advent of the CE marking did not represent anything new to
most global manufacturers.  The old VDE CISPR 22 requirements were not
unlike the present harmonized EMC standards.  Many European countries
required products to meet IEC 950 or their equivalent before the Low 
Voltage Directive.  So the CE marking is mostly a difference in required
documentation, not a difference in the design of the products.

It is my understanding that NO ITE products may now be accepted by EU 
member states without CE marking attesting to cconformity with the EMC 
and Low Voltage Directives.

Re: EMC Directive

1996-04-18 Thread Steve Chin
I agree with Tony that a RAID (not RAID Array - there's no such thing!) is 
unlikely to be found in a residential installation, with one caveat. The RAIDs 
that my company produces are becoming used in an increasingly large amount by 
people producing digital video. Most of these people either work out of their 
homes or they have shops in small offices located in residential areas.

The only good thing I can see from this situation is that they don't use RAID 3 
or RAID 5 units. They prefer the speed they get from a RAID 0 system.

Thus, we qualify our RAID 3/5 systems to class A (since they're used almost 
exclusively by banks, magazines, newspapers, and the sort), and our less 
complicated RAID 0 systems to class B for EMC.

We qualify the safety of all of these systems to the various variations of the 
950 standard, as required by the markets in which we sell.

60MHz systems can be problematic, especially if you're running single-ended 
SCSI. I hope you're not, since the 60MHz stuff has a lot of problems that are 
EMC and non-EMC related if you're single-ended. Are you running 60MHz 
interfaces on the disk drives, the RAID controller, and the host? If so, you 
have fewer problems than if you're mixing in fast SCSI with Ultra (should I 
have mentioned that word?).

Well, good luck, Philip. Disk drive systems are such fun!

RE: EMC Directive

1996-04-16 Thread Tony Fredriksson

Hi,

A RAID Array is not the type of product that will turn up in
a residential application.  It is not under the scope of EN 60555-2.
It is under the scope of the 61000-3-2 which was published in
the OJ last September.  That topic has pretty much been beat to
death on this alias, but we could revive it and smack it
around all over again (not this again!!!).

This product falls squarely under the category of ITE and thus
is subject to the Generic Immunity and Emissions Standards
and EN55022.  Depending on how you define its use environment,
you can qualify it for Class A EMI with restrictions on use in the
instruction manual or Class B EMI for unrestricted sale and use.
Those restrictions for Class A would specifically exclude use
of the product in residential environments and perhaps even
exclude powering the product of power supply mains which are
shared by residential users.

The design considerations are not really special wrt to other
ITE equipment.  Of course all of the considerations on what
to do to design a product with 60 MHz fundamentals within
can and does fill books.  Hopefully you or someone else in
your company has some experience with EMI design or you
may want to hire a good consultant in the design phase of the
project.  I think there are quite a few good ones on this alias.

To Whom It May Concern,

I got details of your forum through an e-mail transmission to one of
my associates, by Ron Pickard.
 I would appreciate any information you may be able to supply
concerning the EMC Directive, in relation to possible problem areas
when developing our new enclosures for RAID porducts.
The basic enclosure houses a controller (crytsals on this controller
operate at 60 Mhz max.) And three 150W hot replacement PSU's.
What sort of areas should we pay particluar attention to in the
design?
Would it be correct to state that the PSU's fall into the EN60555-2
standard?
As it still seems that the EMC Directive is very vague in this
country I would be glad of any information you may have available.
Thanks and best regards,

Philip Scott - Cork, Ireland.
