CAUTION
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.
