Wire the Modules
After the module is properly installed, wire the modules by using this procedure. To provide
proper operation and high immunity to electrical noise, always use shielded wire.
Do these steps to wire your module.
1. At each end of the cable, strip some casing to expose the individual wires.
2. Trim the signal wires to 5 cm (2 in.) lengths, stripping about 5 mm (0.2 in.) of insulation
away to expose the end of the wire.
3. At the 1769-HSC module’s input end of the cable, twist the drain wire and foil shield
together, bending them away from the cable, and apply shrink wrap, grounding the shield
at this end by using as short a lead-length as possible.
4. At the other end of the cable, cut the drain wire and foil shield back to the cable and
apply shrink wrap.
5. Connect the signal wires to the terminal block, connecting the other end of the cable to
the input device.

ATTENTION: To prevent shock hazard, care should be taken when wiring the
module to signal sources. Before wiring any module, disconnect power from the
system power supply and from any other source to the module.
Do not wire more than two conductors on any single terminal.
ATTENTION: Be careful when stripping wires. Wire fragments that fall into a
module could cause damage at powerup.
