5. Arrange the bunches according to size from thickest to the thinnest between the EMI
conductive cushions.
6. If more than one cable go through a grommet, seal the grommet by applying Loctite
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 laid
against sharp edges. When running cables to or from the swing-out frame, leave enough
slack at the hinge to allow the frame to open fully.
Connecting to the control unit (A41)
Connect the conductors to the appropriate terminals of the control unit or terminal block
X504 (L504).
Connect the inner twisted pair shields and all separate grounding wires to the grounding
clamps below the control unit.
The drawing below represents a drive with additional I/O terminal block (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 the
wire with its return wire reduces disturbances caused by inductive coupling.
At the other end of the cable, leave the shields unconnected or ground them indirectly via
a high-frequency capacitor with a few nanofarads, eg. 3.3 nF / 630 V. The shield can also
be grounded directly at both ends if they are in the same ground line with no significant
voltage drop between the end points.
