Watlow EZ-ZONE ® RMS Module • 25 • 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 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.
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.
Suppressor 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 for AC load or
a diode for a DC load .
