cabinet, the internal wiring must comply with the
EMC standard. Fig. 23 shows an example of a VSD
built into a cabinet.

Fig. 24 shows an example when there is no metal
mounting plate used (e.g. if IP54 variable speed drives
are used). It is important to keep the “circuit” closed, by
using metal housing and cable glands.

Connect motor cables
1. Remove the cable interface plate from the VSD
housing.
2. Put the cables through the glands.
3. Strip the cable according to Table 8.
4. Connect the stripped cables to the respective motor
terminal.
5. Put the cable interface plate in place and secure
with the fixing screws.
6. Tighten the EMC gland with good electrical contact
to the motor and brake chopper cable screens.
Placing of motor cables
Keep the motor cables as far away from other cables as
possible, especially from control signals. The minimum
distance between motor cables and control cables is
300 mm.
Avoid placing the motor cables in parallel with other
cables.
The power cables should cross other cables at an angle
of 90°.
Long motor cables
If the connection to the motor is longer than 100 m (40
m for models 0003-0018), it is possible that capacitive
current peaks will cause tripping at overcurrent. Using
output coils can prevent this. Contact the supplier for
appropriate coils.
Switching in motor cables
Switching in the motor connections is not advisable. In
the event that it cannot be avoided (e.g. emergency or
maintenance switches) only switch if the current is
zero. If this is not done, the VSD can trip as a result of
current peaks.
