Connection procedure (frame R8i, limited scope version)


The following procedure instructs how to connect the control cables of a supply unit. See
the circuit diagrams delivered with the supply unit.
Note: The I/O of the supply unit is mostly reserved for the internal use.
The power cables are routed to the cabinet through the bottom and there is no auxiliary
control cubicle as standard. The extra cubicle is only added if there is a lot of options.
1. Open the cubicle door.
2. Undo the locking screws at the edge of the swing-out frame (2a) and open the frame
(2b).
3. Undo the screws of the shroud in the lower part of the cubicle. Lift and remove the
shroud.
4. Run the cables into the inside of the cabinet through grounding cushions.
•
Seal the cable with a rubber grommet (cut suitable hole to it).
•
Run the cables between the cushions. 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.
•
Fasten the cable to the support above the cushions with a cable tie.
5. 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.
•
Tie the cables to provide strain relief.
•
To allow the swing-out frame to open properly, leave some slack in the cable (if the
cable needs to be run to a device in the frame).
6. Cut the cables to suitable length. Strip the cables and conductors.
7. 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.
8. Connect the conductors to appropriate terminals (see the circuit diagrams delivered
with the unit).
9. Fasten the shroud and the swing-out frame.
10. Close the door.
