the UPS output. If no load exists, the indicator bar goes out completely. As the
load increases, the bar lights up from right to left in 20, 50 and 100%
increments. If the red indicator light also goes on, then the UPS is overloaded.

Danger!
Mains voltage exists at all plug connections on the rear panel (exception:
RS232 interface) have mains power potential when connected.
Even when disconnected, dangerous high voltages can exist at the plug
connections due to charged capacities inside the equipment.
a) Fuse at mains power input:
The mains input is enabled when the fuse is inserted. The fuse is triggered in
the event of high overcurrents or an equipment defect (e.g. internal short-
circuit) and the device is immediately disconnected from the connected mains
power supply.
To simulate a mains power failure, simply remove the fuse or disconnect the
plug connection for the mains power supply.
If all UPS connections have been established and the fuse has been inserted,
the charging unit automatically becomes active, i.e. charging of the internal
battery pack is already underway, without having to start the UPS.
a) Mains power

IEC 10A power plug for mains voltage.
The protective earth conductor must be connected without fail!
Please always observe the input voltage indicated on the identification label or
in the technical data of this manual.
