DC SYSTEM. This system must use a battery of 48 or 125 VDC to supply tripping energy to the generator circuit breaker. All such installations must isolate (trip) the generator in such a manner that: a manual operation or a time-delayed automatic synchro-check or voltage check supervised operation is required to close the generator or point-of-contact breaker (contactor) after the GPU Energy source has returned to normal. Under no circumstances is the generator contactor (breaker) to close immediately upon restoration of the GPU Energy source. An amber or yellow lamp shall provided to monitor the DC source and shall have a nameplate.
