8 Operating and Maintenance

8.1Operation

1.Make sure that the phase sequence is correct if you are using a three-phase mains connection (L1, L2, L3). If you are using a single-phase mains connection, make sure that phase L1 has been selected and correctly connected to the UPS.

2.Furthermore, make sure that the neutral conductor has been connected properly and that the system is adequately earthed.

3.Check the polarity of the battery system. Make sure that the (+) and (-) poles of the connection match those of the battery casing. Now switch the battery system "ON" using the fuse load break switch.

4.Switch the input protection switch on the rear of the UPS to "ON". The fans start operating immediately.

5.Now set the "system start switch" behind the slot cover cap of the LC display to "ON" and follow the instructions on the LC display.

Note: The diagrams below show examples for the displays with a three-phase connection for the UPS; in spite of the slight differences they also apply accordingly to the AC voltage connection. The content of the diagrams is only intended for display purposes.
