Can the following damage the LE.
Controller is constructed with 2 Power inputs with 3 prong polarized plugs.
Connected one 3 prong extension cord to LE and plugged the other end of the 3 prong extension cord into a 120 V wall outlet. (polarity correct)
Connected a second 3 prong extension cord to the second power lead on LE, then, because the ground (3rd) prong was missing on the other end of the extension cord, accidently plugged it into a separate 120 volt circuit wall outlet with the polarity reversed.
Is the LE robust enough to withstand this situation, or will there be some damage I need to track down?
The LE worked, but it took it some time before the channels started to blinky blink.
Everything tested out correctly when I run the built in test while it was in this power-up configuration.
It was an old extension cord and even though it was designed with 3 prongs, I don’t think the neutral side of the plug was the larger size; hence the ability to get the polarity wrong on one side of the power inputs.
I know, I know; I should not have done this, but I was not the one on the other end of the cord who plugged it in and I did not make sure the person plugging it in made sure the polarity was correct.
