11.1 Generator ON Facility
The generator ON facility must use a normally open contact that closes to indicate that a
generator is running and supplying input power to the UPS. When used, this facility
disables the UPS static bypass and prevents the UPS from transferring the load into the
generator power supply. The user may also elect prevention of battery charging while
on generator input. Both or either of these features may be selected via the control
panel. (See section 7.3.8, Set Up)
