4.5 Operation
At first the UPS must be connected to a suitable mains
wall plug. Then set the mains switch to the ON-position.
Following to that procedure output voltage will be
available. The green LED
will be illuminated
or blinking when mains voltage is within nominal range;
if not, another LED will be illuminated in connection
with a sounding danger signal.
In normal operation,
mains voltage is available, the
integrated battery charger will float the battery and the
inverter will be set to the stand-by mode by the
monitoring. In case of mains blackout as well as with de-
creasing mains voltage to 85% or increasing mains volta-
ge to 110% the inverter
be set to the stand-alone mo-
de supplying the load with AC voltage.
In case of battery undervoltage a danger signal of the
UPS will sound for approx. 1 to 3 minutes. Afterwards
the battery will be disconnected by the UPS.
In this case please
off the UPS by the mains
switch
After mains has been restored, the UPS must be switched
on manually by the mains switch for battery charging to
overcome the next mains failure.
