Re: [PSES] Critical Components definitions

Actually I wasn't just referring to their selection of components (in itself an issue, they pretty much included the entire BOM) but the information in the list. They haven't provided any of the NRTL mark info, critical tech specs, or applicable standards the parts are certified to after

Re: [PSES] Critical Components definitions

I have always viewed the Safety Critical Components List (SCCL) as kind of like a Cheat Sheet or Road Map to a safety inspection. As probably most Safety Inspectors, I wouldn't even think about starting a safety evaluation without the SCCL up front. Otherwise, you would be crawling around

[PSES] Concerning FCC classification of digital devices

Dear list members, Being an independent testing facility, we have received a question from a costumer regarding FCC classification. The consumer’s product is a small portable device for use with a musical instrument. When the product is used normally, it is attached to the instrument by

Re: [PSES] Concerning FCC classification of digital devices

Hello Niels, Sorry to disappoint your customer but this is a computer peripheral. They would connect it to their computer for updating software, etc. Regardless of how rarely they do it… the fact is, they do it. It’s like a mobile phone, or a GPS Sat Nav., or a camera, etc. It is not

Re: [PSES] Critical Components definitions

All of our parts are source controlled either by a drawing or specific Manufacturer's and their specific part numbers. If no drawing, the Manufacturer names and part numbers are loaded in SAP and can only be added/changed by Engineering under ECO control. The purchasing department is only

Re: [PSES] Critical Components definitions

All makes perfect sense. In the case of a project I have now which is not typical our outsource manufacturer has already gone through the process of obtaining passing EMC and safety reports from their independent agency in the US (who I won't name here but is not an OSHA approved NRTL, they

Re: [PSES] Concerning FCC classification of digital devices

In my opinion the customer's analysis is correct - and he's ultimately responsible for the decision right or wrong. I have had a similar experience. It was battery powered and could be programmed at the factory through a USB hub - factory only customers can't use the connection to program or

Re: [PSES] Critical Components definitions

(who supposedly has been shipping CE marked product to EU on their own for years with no issues) Absence of proof of non-compliance is not proof of compliance (or so what in short hand :) ) Whilst you're chasing the safety - compare built state subjected to EMC with current build state.

Re: [PSES] Concerning FCC classification of digital devices

HI Neils Your client should understand that it is not his point of view that matters, it is what the FCC says about the device and what they say needs to be done in order for the device to be authorized. The simple fact that it can, at any time, connect to a PC and download software makes this

Re: [PSES] use of AC contactor in PV application in US/CAN

From: Boštjan Glavič Sent: Thursday, March 13, 2014 01:01 Is anyone familiar if it is allowed to use a contactor instead of circuit breaker in PV application to disconnect inverter from the grid? NEC in Article 690 does not specify it precisely. What standard needs to comply this

An on-board header is much less an issue; connecting only the power pins on a micro-USB connector eliminates data transfer as a defining capability. Cortland Richmond On 3/14/2014 12:08 PM, Dward wrote: The simple fact that it can, at any time, connect to a PC and download software makes

Re: [PSES] Concerning FCC classification of digital devices

That's correct Cortland. If the USB is only used for charging (not data transfer), then it does not count as a 'peripheral' and therefore Verification as Digital Device can be used. Michael. Michael Derby Regulatory Engineer ACB Europe From: CR [mailto:k...@earthlink.net] Sent:
