PM Integrated Controller • 22 • 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 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
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 terminal
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 – Substitution of
component may impair suitability for
CLASS I, DIVISION 2.
Warning:
ç
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.
