Units with EMI conductive cushions only:
Run the cables between the cushions as shown below. Strip the cable at this location to enable proper
connection of the bare shield and the cushions. Tighten the cushions firmly onto the cable shields.
If the outer surface of a cable shield is non-conductive, turn the shield inside out as shown below and
apply copper foil to keep the shielding continuous. Do not cut the grounding wire (if present).
On top entry units, sort the cables so that the thinnest and thickest cables are at opposite ends of the
opening.
Run the cables to the appropriate terminals. Wherever possible, use the existing cable trunking in the
cabinet. Use sleeving wherever the cables are laid against sharp edges. When running cables to the
swing-out frame, leave some slack in the cable at the hinge to allow the frame to open fully. Tie the cables
to the cable supports wherever necessary.
Cut the cables to suitable length. Strip the cables and conductors.
Twist the cable shields into bundles and connect them to the ground terminal nearest to the terminal block.
Keep the unshielded portion of the cables as short as possible.
Connect the conductors to appropriate terminals (see the chapter Motor control and I/O board (RMIO) and
the circuit diagrams delivered with the unit).
Refit any shrouds removed earlier. Close the swing-out frame, refasten, and close the cabinet door(s).
