Determining the Cable Length
Determine the length of cable you will need to connect a channel to
its input or output device. Remember to leave additional length to
route the drain wire and foil shield for earth grounding.
Wiring the Analog Module
After the analog module is properly installed in the chassis, use the
following wiring procedure. Belden cable #8761 is recommended
when wiring analog modules. This section assumes that you have
properly installed the analog module.
To wire your analog module follow these steps and refer to the
illustrations on the next page.
1. Designate the end of the cable where the drain wire and foil
shield is earth grounded as END 1. Designate the other end as
END 2.
2. At each end of the cable strip some casing to expose the
individual wires.
3. Trim the signal wires to 2 inch lengths. Strip about 3/16 inch
(4.76mm) of insulation away to expose the end of the wire.
4. At End 1, twist the drain wire and foil shield together, bend them
away from the cable, and apply shrink wrap.

ATTENTION
Before wiring any analog module, disconnect power
from the SLC 500 system and from any other source
to the analog module.
