Chapter 2 Install and Wire

Warning:

Óç

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

peripheral 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

(30 to 12

AWG) single-wire termination or

two 1.31 mm

(16 AWG)

• 0.8 Nm (7.0 lb.-in.) torque

Note:

Adjacent terminals may be labeled

differently, depending on the model

number.

Note:

To prevent damage to the control-

ler, do not connect wires to unused
terminals.

Note:

Maintain electrical isolation between

analog input 1, digital input-outputs,

switched dc/open collector outputs

and process outputs to prevent
ground loops.

Note:

The control output common termi-

nal and the digital common terminal

are referenced to different voltages

and must remain isolated.

Note:

This Equipment is suitable for use in

CLASS I, DIVISION 2, Groups A, B,

C and D or Non-Hazardous locations
only. Temperature Code T4A

Warning:

Explosion Hazard - Dry contact clo-

sure Digital Inputs shall not be used

in Class I Division 2 Hazardous Loca-

tions unless switch used is approved
for this application.

Warning:

Explosion Hazard – Substitution of

component may impair suitability

for CLASS I, DIVISION 2.

Warning:

Explosion Hazard - Do not discon-

nect while the circuit is live or

unless the area is known to be free

of ignitable concentrations of flam-

mable substances.
