Common Mode Filter If common mode filter or light common mode filter is required (see
Motor Connections / Requirements Table in Safety Instructions) , lead
the motor cable phase conductors through the toroidal cores as
follows:
1. Connect the twisted cable screen to the PE terminal.
2. Wrap the phase conductors together with the silicon rubber tape
delivered with the toroidal cores to provide thermal insulation for
the conductor insulator. Cover the part of the cable which will be
left inside the core(s) + 20 mm below. Approximately 1.5 metres of
tape is needed per cable. Each turn must overlap the previous turn
by half the width of the tape.
3. Bind the conductors tightly with non-conductive electrical tape and
a heat-resisting non-metallic cable tie in order to prevent
conductor insulation damage caused by the core edges.
4. Slide the core(s) onto the taped part of the phase conductors.
5. Bind the cores together and onto the taped part of the phase
conductors with heat-resisting non-metallic cable ties.
