Wiring Notes
Maximum wire size termi-
nation and torque rating:
0.0507 to 3.30 mm2 (30
to 12 AWG) single-wire
termination or two 1.31
mm2 (16 AWG)

Adjacent terminals may
be labeled differently
depending on the model
number.
Do not connect wires to
unused terminals.
Maintain electrical isola-
tion between analog
input 1, digital input-
outputs, switched dc/
open collector outputs
and process outputs to
prevent ground loops.
This equipment is suit-
able for use in CLASS
I, DIVISION 2, Groups
A, B, C and D or Non-
Hazardous locations only.
Temperature Code T4A
Wiring Warnings
ç
Use National Electric
(NEC) or other country-
specic standard wiring
and safety practices
when wiring this control-
ler to a power source,
electrical sensors or pe-
ripheral devices. Failure
to do so may result in
damage to equipment
and property, and/or in-
jury or loss of life.
Explosion Hazard - Dry
contact closure Digital
Inputs shall not be used
in Class I Division 2 Haz-
ardous Locations unless
switch used is approved
for this application.
Explosion Hazard – Sub-
stitution of component
may impair suitability for
CLASS I, DIVISION 2.
Explosion Hazard - Do
not disconnect while the
circuit is live or unless
the area is known to be
free of ignitable concen-
trations of ammable
substances.
