Operation

Maintenance Mode

For maintenance or repair, the Liebert® APM™ may be operated in maintenance mode. To place the Liebert APM in maintenance mode, follow the instructions in 10.4 - Switching the UPS from Normal Operation to Maintenance Bypass.

! WARNING

Risk of arc flash and electric shock. Can cause equipment damage, injury and death

The UPS input and output must be protected with external overcurrent protection devices. In maintenance mode, the input and output busbars remain energized and present an electric shock hazard.

Sleep Mode

Sleep mode allows equal run time on all power modules. The modules will put themselves offline for a programmable period of 0-30 days. Once a module goes offline, another module will come back online. Each module will rotate being online and offline.

Paralleling Mode

This option is only available on 208V Input Parallel. This mode requires the buyout panel board paralleling gear. It can parallel the following:

•two APM’s

•45kW or 90W frames in any module capacity

•redundant

•can allow up to 180kVA of load capacity

A Sharing Inductor is required for Parallel units.

NOTE

To parallel non-208 input voltages, an upstream transformer must drop the input voltage to 208V before the paralleling gear.
