Connection procedure
Turn the supply (rectifier) unit switch-disconnector into open position.
Release the door handle and open the door of the control and I/O cubicle.
Remove the two locking screws at the edge of the swing-out frame and open the frame.
Run the cables into the inside of the cabinet through the grommets provided.
Top entry units only:
If several cables need to be run through one grommet, use Loctite 5221 (cat. no.
25551) under the grommet to seal the cable entry.
Run the cables between the EMI conductive 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.
