you would rather have the control function occur than have it disabled by a
fault.
I hope this helps, I hope some of our dedicated safety members will jump in and
shed some light.

to the 50 uH developing impedance in the internal branch of the LISN leading
back to the power source, but to the 50 ohm characteristic impedance of the RF
connection to the Spectrum Analyzer. At 1 MHz the reactance of a 6 - 7 uH
inductor is around 50 ohms an it increases from there.

Is there an harmonized standard that covers lawn mowers, chain saws,
emergency generators, and other non-vehicular internal combustion
applications, or are you expected to make the IC engine meet the generic
emission requirements of 50081-1?
Thanks in advance for any help,

where the installation is taking place.

I don't know why you were cautioned not to rinse, I would have thought it
desirable, but the acid will preferentially eat the zinc coating because Zinc is
higher in the electrochemical reduction series than the underlying iron
(sacrificial anode).
