3.6.1.6 Connecting the motor cable
The screened cables between the variable frequency drive and the motor
should be as short as possible.
Figure 71: Connection on motor side
▶ Connect the screening, on both sides and across a large area
(360° overlap), to the protective earth (PE) .
The power screening's protective earth (PES) connection should be in
the immediate proximity of the variable frequency drive and directly on
the motor terminal box.
▶ Prevent the screen earth kit from unbraiding, i.e. by pushing the
separate plastic covering over the end of the screen or by inserting a
rubber grommet on the end of the screen. Connect the screen braid
onto the end across a large area (PES).
Alternatively, you can twist the screen braid and connect it to the
protective earth using a cable lug. In order to prevent EMC interference,
this twisted screen connection should be as short as possible
(recommended value for the twisted cable screen: b ≧ 1/5 a).
