Frequency converter maintenance
The frequency converter does not require a preventive maintenance.
However, it is recommended to carry out the following inspections by the
user in regular intervals:
– Check condition and tightness of the cable connections.
Replacing the frequency converter
If a frequency converter exchange was made, it is to be noted, that all
shielded cables are properly attached again!
Electric shock hazard in contact with energized components
Keep the cover plate of the frequency converter closed at all times!
► Before interventions take place in the device, the power supply
must be switched off.
► After switching off the power supply, wait at least 10 min. before
working on the equipment, because the internal condensers need
this time for discharging!
► Verify that the parts are deenergized by means of a voltmeter!
