Wiring the Modules
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.

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.
