Connecting the control cables for the supply unit

Default I/O connection diagram
See chapter The control unit .

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.
