6. Connect the conductors to the appropriate terminals of the control board and
tighten to 0.5...0.6 N·m (0.4 lbf·ft).
Digital signals
The figures for frames
show an example of connecting a cable. Make the connections according to
the macro in use.
7. Frames R4...R8: Cut an adequate hole into the rubber grommet and slide the
grommet onto the cable. Slide the cable through the hole in the lead-through
plate and attach the grommet to the hole.
8. Ground the outer shield of the cable 360° under the grounding clamp. Keep
the cable unstripped as close to the terminals of the control board as possible.
Frames R5...R8: Secure the cables mechanically at the clamps below the control
board.
If you use double-shielded cables, ground also the pair-cable shields and
grounding wire at the SCR terminal.
9. Route the cable as shown in the figures
and R6...R8 (page
10. Connect the conductors to the appropriate terminals of the control board and
tighten to 0.5...0.6 N·m (0.4 lbf·ft).
11. Tie all control cables to the provided cable tie mounts.
Note:
• Leave the other ends of the control cable shields unconnected or ground them
indirectly via a high-frequency capacitor with a few nanofarads, e.g., 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.
• 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.
