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
page 15.
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 50 mm (2 inch) lengths. Strip 5 mm (about 3/16
inch) of insulation away to expose the end of the wire.
ATTENTION
Before wiring any analog module, disconnect power from the
SLC 500 system and from any other source to the analog
module.
