Operation
The UPS has three operation mode options.
Normal operation
During normal operation, the UPS double converts utility power to conditioned power for the connected load.
Battery operation
During battery operation, the UPS provides power to the connected load from batteries for a finite period of time. The UPS transfers to battery operation if the supply of utility power fails or is outside predefined limits.
Bypass operation
Bypass mode is reached either as a user selection or automatically.
•Bypass mode can be selected through the Control menu screen on the PowerView display
•The UPS will automatically switch into bypass mode if:
–Both normal and battery operation modes are unavailable
–An output overload condition occurs
–The UPS has an internal fault
During bypass operation the utility power is connected to the load, bypassing the internal converters. If bypass mode becomes unavailable the UPS will automatically switch to mains power. In the event that mains power is unavailable the system will switch to battery power.
Battery LED
The battery LED is located on the front bezel of the XLBP. During normal operation the LED is not illuminated.
