Cable connections
Section 3-2
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 con-
trol 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 003-018),
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 cur-
rent is zero. If this is not done, the VSD can trip as a result of current peaks.
