[GreenKeys] UGC-136BX Power

FYI ... I've had an earth leakage breaker trip several times when
connecting the power connector to the back of the teleprinter (when the
machine is turned off).

I think what is happening is, since all the pins are the same length, the
active and earth sometimes connect before neutral. There is a filter block
between the power connector and the switch which could give enough current
to pop the earth leakage breaker.

Anyway .. connect the Amphenol connector before plugging the NEMA plug into
the power point (and, when disconnecting, remove from the powerpoint before
disconnecting from the teleprinter).
