3.5 — Turning the Generator Off When Operating Under Load
NOTE: Important! To turn the generator off during prolonged utility outages to perform maintenance or conserve
fuel, follow 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.
3.6 — Manual Transfer Operation
DO NOT attempt to activate the transfer switch manually until all power voltage supplies to the switch have been
completely turned off. Failure to turn off all power voltage supplies may result in extremely hazardous and possi-
bly fatal electrical shock.
Prior to automatic operation, manually exercise the transfer switch to verify that there is no interference with proper operation of the mechanism.
Manual operation of the transfer switch is required if electronic operation should fail.
