6 Start-Up
Compare the setting of the nominal output voltage of the UPS
with the rated voltage valid in your country. The factory
presetting is 230 V. Changes to 220 VAC or 240 VAC can be
made with the software “CompuWatch”.
Switching on the PROTECT 1. on the mains
1. Make sure that all connections have been made
according to the installation instructions.
2. Make sure that all loads are switched off.
3. Put the “maintenance switch” manual bypass
switch (no. 3, p. 26/27) on the back of the UPS
back to the “USV“ position. Next fasten the cover
again with the 4 previously removed screws.
4. Now insert the back-up fuse in your low-voltage main
distribution (where the UPS system is connected to
the mains on the input side) or switch on the
corresponding line protection switch there.
5. Next actuate the mains input miniature circuit
breakers on the UPS (no. 2, p. 26/27). Move this
to the "ON" position.

Factory presetting: The loads are supplied via
the integrated bypass, which connects the
phase L1 with the UPS output. Do not switch on
your loads yet, however.
6. Now switch on the inverter of the UPS. To do this,
press the ON pushbutton for approx. 2 seconds.
7. After switching on, the UPS carries out a self-test,
during which the LED’s for load and battery state
go on and off consecutively in increasing order.
After the successful synchronization of the
inverter, the Inverter LED lights up a few seconds
later, whereby the UPS is now in normal
operating mode. When the mains supply is intact
(mains within tolerance), the "Line" LED also
lights up.
