Watlow EZ-ZONE RMC - Manual (Page 33)

Warning:
ç
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:
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.
