9.2.1 Any Mode Shutdown
The purpose of Any Mode Shutdown is to shut down the UPS output by turning off the rectifier, inverter, and static switch
so that there is no power to the loads. Activation of the Any Mode Shutdown will be logged as an event in the event
history log.
Any Mode Shutdown can be operated locally or remotely:
•
Local
Any Mode Shutdown can be performed by shorting the Pins in Set 3.
•

Any Mode Shutdown can be performed using a switch connected to the Pins in Set 3 and mounted at a
remote location.
NOTES:
