Mechanical installation
WARNING!
Do not attempt any work on a powered drive. After switching off and
disconnecting the power supply, always allow the intermediate circuit capacitors
5 minutes to discharge before working on the frequency converter, the motor
or the motor cable. Check (with a voltage indicating instrument) that the drive
is in fact discharged before beginning work.

Installing non-enclosed (IP00) filters
Lift the filter by the lifting holes to the installation position. Fasten the filter with four
screws at the fastening points in the mounting legs or with FOCH0320-50 and
FOCH0610-70 alternatively with two screws in the upper mounting leg and four screws
in the base plate of the filter core.
￭
Installing enclosed (IP22) filters
1. Measure the fastening hole locations and make the holes to the wall.
2. Insert the fixing anchors to the holes and start fastening screws in the anchors.
Use a sufficient number of screws and drive them long enough into the wall to
make them carry the weight of the filter.
3. Put the filter on the screw.
4. Tighten the screws.
