American Power Conversion 240-320kW400V manual Economy Mode, Operation

Operation

3.4Economy Mode

When the UPS is running in Economy Mode, the load will be supplied directly from mains and output voltages are UPS monitored. In the event of a mains disruption, the UPS will switch to battery mode without affecting the load.

Prior to switching to bypass mode, leave the system running in normal mode for 8-10 hours to charge batteries to full capacity.

To keep batteries fully charged, UPS is pre-programmed to switch back to normal operation whenever necessary.

Economy Mode not available for parallel configurations.

At start-up, the system will at first go into normal operation to ensure a fully charged battery, and it will then switch into bypass after the programmed time (8-10 hours).

NOTICE!

Check cable dimensions as input power factor is not corrected with UPS running in Economy Mode.
