1. Run the output (motor) cable into the cubicle through a cable gland or grommet. 360°
grounding of the cable shield is recommended to suppress interference. In case a
grounding cable gland is available, remove the outer jacket of the cable where it passes
through the cable gland.
2. Remove the shrouds covering the terminals of the inverter module.
3. Cut the input (DC) and output cables to suitable length and strip the ends of the individual
conductors.
4. Twist the shield strands of the output cable together to form a separate conductor. Crimp
a suitable ring terminal onto the end, and cover the remaining bare screen with tape as
shown below. Do the same for the input cable if it is a shielded type.
5. Insert the conductors to the terminals and tighten the Allen screw. Note that the original
screw lugs can be replaced by crimp ring terminals connected directly to the connection
post. Make note of the order and orientation of the washers on the connection post.
6. Connect the cable shields to ground near the terminals.
7. Reinstall the terminal covers.
8. Secure the cables inside and outside the cabinet mechanically.
9. Tighten the cable gland if present.
10. Connect the motor cable as shown below.
