3.4 Operating modes
3.4.1 Mode “ON-LINE”
In on-line mode, the load is connected to the inverter (INV) and the rectifier (Line1) is supplied by the
main utility supply. The on-line mode protects the load from any utility main disturbance or failure.

In the unlikely event of an inverter fault or overload condition, the UPS will transfer the load
automatically and without interruption to the static bypass (transfer time = 0 s).
