Operating modes

6.6.1

Mode "ON LINE" (INVERTER MODE)

The ON-LINE-Mode is the UPS-Operating Mode in which the load is supplied through the RECTIFIER
and INVERTER.
Using the control panel the UPS can easily be transferred to the ON-LINE-Mode. The ON-LINE-Mode
provides the highest degree of protection, especially in the event of a mains disturbance or failure.
This operating mode is always recommended if the critical loads (computer systems) will not tolerate
any interruption of the supply (not even the shortest). 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-mains supply (transfer time = 0).
6.6.2

Mode "Standby"

The Standby mode is part of the Xtra VFI operating mode
Standby mode have the INVERTER OFF.
The Xtra VFI operating mode switches the modules from ON-LINE to Standby or from Standby back
to ON-LINE fully automatically. Read through the
works.
