in the appropriate installation and owner’s manuals.
3. Educate the end-user on the proper operation, maintenance
and service call procedures.
Important! If the end user ever finds it necessary to turn the
generator off during prolonged utility outages to conserve on
fuel, educate them on these simple, but important steps:
To turn the generator OFF (while running in AUTO and online):
1. Turn OFF (or OPEN) the main Utility disconnect.
2. Turn OFF (or OPEN) the Main Line Circuit Breaker (MLCB) on
the generator.
3. Turn the generator OFF.
To turn the generator back ON:
1. Put the generator back into AUTO and allow to start and
warm-up for a few minutes.
2. Turn ON (or CLOSE) the MLCB on the generator.
The system will now be operating in its automatic mode. The main
utility disconnect can be turned ON (or CLOSED), but to shut the
unit off, this complete process must be repeated.
