Connect motor cables
1. Remove the cable interface plate from the AC drive
housing.
2. Put the cables through the glands.
3. Strip the cable according to Table 11.
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
(12 in).
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 (330
ft)(for powers below 7.5 kW (10.2 hp) please contact CG
Drives & Automation), 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 AC drive can trip as a result of current
peaks.

mains cables for larger
frame sizes
IP54 - FLD 48-090 to 295 (Frame sizes E - F) and
FLD 69-090 to 200 (Frame size F69)

To simplify the connection of thick motor and mains cables
to the AC drive, the cable interface plate can be removed.
Fig. 35 Connecting motor and mains cables.
1. Remove the cable interface plate from the AC drive
housing.
2. Put the cables through the glands.
3. Strip the cable according to Table 11.
4. Connect the stripped cables to the respective mains/
motor terminal.
5. Fix the clamps on appropriate place and tighten the
cable in the clamp with good electrical contact to the
cable screen.
6. Put the cable interface plate in place and secure with the
fixing screws.
