RME Module • 21 • 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 la-

beled differently, depending on

the model

number.

Note:

To prevent damage to the con-

troller, do not connect wires to

unused terminals.

Note:

Maintain electrical isolation

between digital input-outputs,

switched dc/open collector out-

puts and process outputs

to

prevent ground loops.

Note:

If the last two digits of the part

number are "12", this equip-

ment is suitable for use in

CLASS I, DIVISION 2, Groups

A, B, C and D or Non-Hazard-

ous locations

only. Temperature

Code T4

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.

Quencharc 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.
