Connect motor cables<br />

1. Remove the cable interface plate from the AC drive<br />

housing.<br />

2. Put the cables through the glands.<br />

3. Strip the cable according to Table 7.<br />

4. Connect the stripped cables to the respective motor<br />

terminal.<br />

5. Put the cable interface plate in place and secure with the<br />

fixing screws.<br />

6. Tighten the EMC gland with good electrical contact to<br />

the motor and brake chopper cable screens.<br />

Placing of motor cables<br />

Keep the motor cables as far away from other cables as<br />

possible, especially from control signals. The minimum<br />

distance between motor cables and control cables is 300<br />

mm.<br />

Avoid placing the motor cables in parallel with other cables.<br />

The power cables should cross other cables at an angle of<br />

90�.<br />

Long motor cables<br />

If the connection to the motor is longer than 100 m (for<br />

powers below 7.5 kW please contact CG Drives &<br />

Automation), it is possible that capacitive current peaks will<br />

cause tripping at overcurrent. Using output coils can prevent<br />

this. Contact the supplier for appropriate coils.<br />

Switching in motor cables<br />

Switching in the motor connections is not advisable. In the<br />

event that it cannot be avoided (e.g. emergency or<br />

maintenance switches) only switch if the current is zero. If<br />

this is not done, the AC drive can trip as a result of current<br />

peaks.<br />

To simplify the connection of thick motor and mains cables<br />

to the AC drive, the cable interface plate can be removed.<br />

Cable interface<br />

1. Remove the cable interface plate from the AC drive<br />

housing.<br />

2. Put the cables through the glands.<br />

3. Strip the cable according to Table 7.<br />

4. Connect the stripped cables to the respective mains/<br />

motor terminal.<br />

5. Fix the clamps on appropriate place and tighten the<br />

cable in the clamp with good electrical contact to the<br />

cable screen.<br />

6. Put the cable interface plate in place and secure with the<br />

fixing screws.<br />
