UPS Operation

The 5000 Series UPS is hardwired to both utility power and the critical loads. The four main operating states are:
1. On-Line Mode: The UPS converts utility power to charge batteries and provides clean power to the load from
the inverter output.
2. Bypass Mode: The unconditioned utility power is routed around the converter-inverter of the UPS and fed
directly to the load.
3. Maintenance Bypass Mode: Unconditioned utility power is wrapped around the entirety of the UPS and fed
directly to the load.
4. Battery Backup Mode: Batteries are discharged to provide power to the load via inverter output.
5. Emergency Power Off (EPO: For emergency use only. Reference Section 13.4 for details.
The UPS can be switched between On-Line and Bypass by pressing and momentarily pressing the RUN/STOP button on
the touchscreen display.

front of the UPS to power up the unit. 15kVA Only: Verify that the status of the control circuit breaker located
on the front door is closed.
2. Verify that the AC Input LED on the front panel lights green. All LED's on the front panel may light for a
moment when the input breaker is turned on. This is normal. The UPS will now be supplying power in the
bypass mode.

UPS/Online mode and then close MCCB4 to provide clean power to the load
4. Press and hold the START button to begin UPS

the UPS screen. Note: do not close battery system breaker before UPS has been started up or before
prompted on the UPS screen.
When running the UPS for the first time or after the power failure backup
operation, The batteries will not be fully charged and battery backup times
maybe lower than expected,

to receive expected run times.
Using the UPS without charging the battery shortens the battery backup
operation time, and may result in unexpected dropped load in case of a power
failure.
6. Press and hold the UPS button on the touchscreen for 2 seconds to begin UPS operation.
7. Press the Quick View button on the Quick Access Toolbar and verify the UPS has input/output power. If the
UPS has backup batteries, verify the batteries are being charged.
