Connection Procedure (Frame R8I And Multiples); Grounding The Outer Shields Of The Control Cables At The Cabinet Lead-Through - ABB ACS880-207 Hardware Manual

Connection procedure (frame R8i and multiples)


WARNING! Only qualified electricians are allowed to do this work. Read the
complete safety instructions of the drive. Ignoring the instructions can cause
physical injury or death, or damage to the equipment.
1. Disconnect the drive from the AC power line and make sure it is safe to start the work.
Do the steps in section
2. Run the control cables into the auxiliary control cubicle as described in section

Grounding the outer shields of the control cables at the cabinet lead-through

3. Route the control cables.
4. Connect the control cables. See the circuit diagrams delivered with the drive.
Grounding the outer shields of the control cables at the cabinet lead-through
Ground the outer shields of all control cables 360 degrees at the EMI conductive cushions
as follows:
1. Loosen the tightening screws of the EMI conductive cushions and pull the cushions
apart.
2. Cut adequate holes to the rubber grommets in the lead-through plate and lead the
cables through the grommets and the cushions into the cabinet.
3. Strip off the cable plastic sheath above the lead-through plate just enough to ensure
proper connection of the bare shield and the EMI conductive cushions.
4. Tighten the two tightening screws (a) so that the EMI conductive cushions (b) press
tightly round the bare shield.
5. Secure the cables mechanically at the lead-through strain relief.
6. Keep the shields continuous as close to the connection terminals as possible.
