Possible cause
The AC input power is not connected
well.
The AC input is connected to the UPS
output.
The EPO function is activated.
The line and neutral conductors of
the UPS input are reversed.
The external or the internal battery is
incorrectly connected.
The battery voltage is too high or the
charger is faulty.
The battery voltage is too low or the
charger is faulty.
The UPS is overloaded
The UPS is overloaded. The devices
connected to the UPS are fed directly
by the electrical network via the
Bypass.
After repetitive overloads, the UPS is
locked in Bypass mode. Connected
devices are fed directly by the mains.
The UPS is over the input current.
The UPS shuts down automatically
because the short circuit occurs on
the UPS output.
The UPS shuts down automatically
because the short circuit occurs on

from the AC power via the bypass.
2. The load is no longer supplied by
the power.
The batteries are not fully charged
The batteries are defective
The short circuit occurs on the
charger output.
The charger does not have any
output and the battery voltage
is less than 10V/PC.
Remedy
Check if the input power cord is
firmly connected to the mains.
Plug the AC input power cord into
the AC input correctly.
Set the circuit in the closed position
to disable the EPO function.
Rotate the mains power socket by
180° and then connect to the UPS
system.
Check if all the batteries are
connected well.
