Possible cause
The AC input power is not
connected well.
The AC input is connected
to the UPS output.
The external or internal
battery is incorrectly
connected.
Battery voltage is too high
or the charger is fault.
Battery voltage is too low
or the charger is fault.
UPS is overload
UPS is overloaded. Devices
connected to the UPS are
fed directly by the electrical
network via the Bypass.
After repetitive overloads,
the UPS is locked in the
Bypass mode. Connected
devices are fed directly by
the mains.
The UPS shut down
automatically because of
overload at the UPS output.
The UPS shut down
automatically because
short circuit occurs on the
UPS output.
A UPS internal fault has
occurred. There are two
possible results:
1. The load is still supplied,
but directly from AC power
via bypass.
2. The load is no longer
supplied by power.
