5. Arrange the bunches according to size from thickest to the thinnest between the
conductive cushions.
6. Wenn mehrere Kabel durch eine Durchführung geführt werden, muss die Durchführung
mit Loctite 5221 (Katalognummer 25551) im Inneren versiegelt werden.
6. If more than one cable go through a grommet, seal the grommet by applying Loc
5221 (catalogue number 25551) inside the grommet.
Routing the control cables inside the cabinet
Use the existing trunking in the cabinet wherever possible. Use sleeving if cables are
against sharp edges. When running cables to or from the swing-out frame, leave eno
slack at the hinge to allow the frame to open fully.
Connecting to the inverter control unit (A41)
Connect the conductors to the appropriate terminals (see page 127) of the control un
terminal block X504 (option +L504).
Connect the inner twisted pair shields and all separate grounding wires to the ground
clamps below the control unit.
The drawing below represents a drive with additional I/O terminal block (option +L504
Without the block, the grounding is made the same way.
Notes:
•
Do not ground the outer shield of the cable here since it is grounded at the lead-
through.
•
Keep any signal wire pairs twisted as close to the terminals as possible. Twisting
wire with its return wire reduces disturbances caused by inductive coupling.
