4. Tighten the terminal screw making sure the pressure plate secures the

wire. Recommended torque when tightening terminal screws is 0.68 Nm
(6 lb-in).

Wire Size and Terminal Screw Torque

Each terminal accepts up to two wires.

Table 2.4 Terminal Wire Considerations

Wire 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.

TIP

If you need to remove the finger-safe cover, insert a
screwdriver into one of the square, wiring holes and gently
pry the cover off. If you wire the terminal block with the
finger-safe cover removed, you will not be able to put it
back on the terminal block because the wires will be in the
way.

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.
