Chapter 2 Install and Wire

Warning:

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

(30 to 12

AWG) single-wire termination
or two 1.31 mm

(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:

Explosion Hazard – Substitution of
component may impair suitability for
CLASS I, DIVISION 2.

Warning:

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
