PM Integrated Controller • 37 • 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
2
(30 to 12
AWG) single-wire termination or
two 1.31 mm
2
(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:
ç
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:
ç
Explosion Hazard – Substitution of
component may impair suitability
for CLASS I, DIVISION 2.
Warning:
ç
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.
