8 Operating and Maintenance
8.1 Operation
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.
