Commissioning/Startup Without AC Power Available (Battery Mode Operation)
1. Check to ensure the upstream mains AC breaker is closed.
2. Turn on the UPS “Enable” switch on the rear of the unit.

6. Emerson recommends closing the UPS input breaker; it is on the front of transformer-free frame
systems and on the rear of transformer-based frame systems. If AC mains becomes available, the
UPS will revert to AC power mode and begin recharging the battery.
NOTE
This will begin the initial system checks and enable power to begin charging the battery
NOTE
Starting the UPS system without AC power will discharge the batteries. If AC mains power is
not restored before the batteries discharge, the USP will shutdown and power will be lost to the
connected equipment. If the UPS reaches the battery EOD level and shuts down, AC mains
power must be present to restart the UPS system.
NOTE
This will begin the initial system checks and automatically enable output power.
