6. Close the UPS output breaker on the rear of the unit.
7. If supplying power to an external distribution panel, close all breakers to provide power to the
equipment. If using the integral distribution PODs on the UPS or MBC, make sure that the
individual POD breakers are closed.
3.10.3 Commissioning/Startup without AC Power Available (Battery-mode Operation)
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.
1. Verify that the up-stream mains AC breaker is closed.
2. Locate the UPS Enable switch on the rear of the unit protected by a clear plastic cover, and
turn it On.
3. Locate the “Battery Start” push button on either of the two control modules, then press and
hold this button for 5 seconds.
The initial system checks begin, and output power is automatically enabled.
4. Press the On/Off button on the LCD panel.
5. When asked to confirm, press Enter (F5 button) to turn On the UPS.
6. Close the output breaker on the rear of the unit.
7. If supplying power to an external distribution panel, close all breakers to provide power to the
equipment. If using the integral distribution PODs on the UPS or MBC, make sure that the
individual POD breakers are closed.
8. We recommend closing the UPS input breaker that 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.
