Note
The Inverter operating modes include Normal mode and Battery mode.
Transfer from Normal Mode to Battery Mode
When the mains supply is interrupted, the UPS will transfer to Battery mode. If you wish to transfer the UPS from
Battery mode to Normal mode, wait few seconds for the mains input to recover. After about ten seconds, the
rectifier will restart automatically, and the inverter will restore the power.
Transfer from Normal Mode to Bypass Mode
In stand-by mode, press and hold the power button. If the rectifier and inverter are normal, the interface shown in
Figure 5-7 will appear, select 'YES' to switch the UPS on.
