Analog Input Wiring
After the analog module is properly installed, follow the wiring
procedure below. To ensure proper operation and high immunity to
electrical noise, always use Belden™ 8761 (shielded, twisted-pair) or
equivalent wire.
To wire your module follow these steps.
1. At each end of the cable, strip some casing to expose the
individual wires.
2. Trim the signal wires to 2-inch lengths. Strip about 3/16 inch (5
mm) of insulation away to expose the end of the wire.

ATTENTION
!
To prevent shock hazard, care should be taken when
wiring the module to analog signal sources. Before
wiring any analog module, disconnect power from
the system power supply and from any other source
to the analog module.
ATTENTION
!
When wiring an analog input, take care to avoid
connecting a voltage source to a channel configured
for current input. Improper module operation or
damage to the voltage source can occur.
Never connect a voltage or current source to an
analog output channel.
