Operating mode
6.4.8.1
Online mode (Inverter mode)
The
Online mode
is the UPS operating mode in which the load is supplied through the
rectifier
and
the
inverter
.
Figure 21: Online mode on Mimic Diagram
The
Online 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 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 = 0ms).
6.4.8.2
Xtra VFI operating mode
Xtra VFI is a complementary operating mode to the online mode. Please refer to the
description.
6.4.8.3
Eco mode (Offline or bypass mode)
In
Eco mode
, the load is supplied from the mains through the static bypass.
