PMI Controller • 40 • Chapter 2 Install and Wire
Warning:
ç
Use National Electric (NEC) or
other country-specific standard
wiring and safety practices when
wiring and connecting this con-
troller 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)
• 0.56 Nm (5.0 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
outputs and process outputs to
prevent ground loops.
Note:
This equipment is suitable for
use in CLASS I, DIVISION 2,
Groups A, B, C and D or Non-
Hazardous locations only. Tem-
perature Code T4
Warning:
ç
Explosion Hazard – Substitution
of component may impair suit-
ability for CLASS I, DIVISION 2.
Warning:
ç
Explosion Hazard - Do not dis-
connect while the circuit is live
or unless the area is known to be
free of ignitable concentrations
of flammable substances.
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.
