Power cable connection procedure

Frames R1i and R2i

WARNING!
Read and follow the instructions given in Safety instructions for ACS880
multidrive cabinets and modules (3AUA0000102301 [English]). Ignoring
the instructions can cause physical injury or death, or damage to the
equipment.
1. Run the output (motor) cable into the cubicle through a cable gland or grommet. In case
a grounding cable gland is available, remove the outer jacket of the cable where it
passes through the cable gland.
2. Cut the input (DC) and output cables to suitable length and strip the ends of the individual
conductors.
3. Twist the shield strands of the output cable together to form a separate conductor and
crimp a ring terminal onto it. Do the same for the input cable if it is a shielded type.
4. Connect the conductors to the terminal blocks. Connect the cable shields to grounding
terminals near the terminal blocks.
5. Secure the cables inside and outside the cabinet mechanically.
6. Tighten the cable gland if present.
