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.
