NOTE:
When using cable in bundles or conduits, consider the
following:
Do not exceed 40% fill capacity in conduits.
•
Do not comb the cable for the first 20 m, where cables are
•
straightened, aligned, and secured in tight bundles.
Loosely place cables and limit the use of tie wraps or hook
•
and loop fasteners.
Separate twisted pair cables from AC power cables.
•
RS-232 and IR connectors
Figure 6 shows how to wire the RS-232 and IR connector.

Figure 6. RS-232 and IR Connector Wiring
NOTES:
The length of exposed wires is important. The ideal length is
•
3/16 inch (5 mm).
If the stripped section of wire is longer than 3/16 inch, the
•
exposed wires may touch, causing a short circuit.
If the stripped section of wire is shorter than 3/16 inch,
•
wires can be easily pulled out even if tightly fastened by
the captive screws.
Do not tin the power supply leads before installing them
•
in the connector. Tinned wires are not as secure in the
connector and could be pulled out.
