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 mm2 (30 to 12 AWG)
single-wire termination or two 1.31
mm2 (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.

Note:

If the last two digits of the part number
are "12", this equipment is suitable for
use in CLASS I, DIVISION 2, Groups A,
B, C and D or Non-Hazardous 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.

Suppressor Note:
Switching pilot duty inductive loads (re-
lay coils, solenoids, etc .) with the me-
chanical relay, solid state relay or open
collector output options requires use of
an R .C . suppressor
