Check and, if required, re-tighten connection terminals.
For further details, see the operating instructions. Danger of electric shock from loaded condensers! Please
always first disconnect the system from the power supply
and wait another 10 minutes before touching the
electrical components. The power condensers require
this time in order to discharge!
Check the DC bus voltage at the system terminal strip of
the frequency converter by measuring this between the
+DC and -DC terminals (the exact position can be found
in the supplied operating manual of the frequency
converter), between the +DC terminal and the chassis as
well as between the -DC terminal and the chassis.
The voltage must read zero in the case of all three
measurements.
