2-6 Installing the Module
You wire the HSCE module by wiring the user power supply and input and
output signals. All connections are made at the terminal block. To wire the
terminal block, follow the procedure below.
1. Turn the terminal block, with the screw-heads facing you, until the
series of terminals is at the top and the

2. Start with the
screws.
3. Strip back the insulation on the wires about 1/4 to 3/8 or 6 mm. Use a
14–22 AWG or a 0.16–3.2 mm
solid type. (If you are using the side-accessible connector,
PPX:2587706–8010, a spade or a ring lug may be attached to the end of
the wire.)
4. Connect the end of the wire to the loosened terminal block screw and
tighten the screw firmly. Once the
series, and continue until the terminal block is completely wired.
NOTE: A stick-on label is provided separately with space available to
identify inputs and outputs. Write in the corresponding input or output
names and apply the label to the flat side of the terminal block. Appendix B
contains worksheets to help you document the input and output labeling.
Separate the power supply wiring from the signal wiring to avoid
introducing noise on the input data lines.
To minimize unwanted noise, follow these wiring guidelines:
Use the shortest possible wires.
Avoid placing signal wires parallel to high-energy wires. If the two
wires must meet, cross them at right angles.
Avoid bending the wire into sharp angles.
Use wireways for wire routing.
When using shielded wires, ground them only at the source end for
better noise immunity.
Place wires so that they do not interfere with existing wiring.
Label the wires.
