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 i 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.
