RMS Module • 25 • Chapter 2 Install and Wire

Warning: ç

Use National Electric (NEC) or other

country-specific standard wiring and

safety practices when wiring and

connecting this controller to a power

source and to electrical sensors or pe-

ripheral devices. Failure to do so may

result in damage to equipment and

property, and/or injury or loss of life.

Note:

Maximum wire size termination and

torque rating:

• 0.0507 to 3.30 mm

2

(30 to 12 AWG)

single-wire termination or two 1.31

mm

2

(16 AWG)

• 0.8 Nm (7.0 in-lb.) torque

Note:

Adjacent terminals may be labeled

differently, depending on the model

number.

Note:

To prevent damage to the controller,

do not connect wires to unused ter-

minals.

Note:

Maintain electrical isolation between

digital input-outputs, switched dc/open

collector outputs and process outputs

to prevent ground loops.

Warning: ç

Explosion Hazard – Substitution of

component may impair suitability for

CLASS I, DIVISION 2.

Warning: ç

Explosion Hazard - Do not disconnect

while the circuit is live or unless the

area is known to be free of ignitable

concentrations of flammable sub-

stances.

Suppressor Note:

Switching pilot duty inductive loads

(relay coils, solenoids, etc.) with the

mechanical relay, solid-state relay or

open collector output options requires

use of an R.C. suppressor for AC load or

a diode for a DC load.
