WARNING: Use National Electric (NEC)
or other country-specific standard
wiring practices to install and operate
the DIN-A-MITE. Failure to do so may
result in damage to equipment and
property, and/or injury or loss of life.
Ó

WARNING: Wiring examples show L2
in phase-to-phase, 200V
Å
(ac) and
above configuration. In phase-to-
neutral, 100 V
Å
(ac) and above
applications, L2 is neutral and must
not be fused or switched. Failure to
follow this guideline could result in
personal injury or death.
Ó

WARNING: Only authorized and
qualified personnel should be allowed
to install and perform preventive and
corrective maintenance on this unit.
Failure to follow this guideline could
result in damage to equipment, and
personal injury or death.

WARNING: Do not use the DIN-A-MITE
Vac-input models with a temperature
controller that includes an RC snubber
circuit across its output. Remove the
RC snubber circuit before placing the
DIN-A-MITE into service.
NOTE: Shorted SCR (silicon- controlled
rectifier) alarm option not available
with multizone input option.

NOTE:
Independent loads do not have to
be on the same phase.
NOTE:
Terminals 2 and 5 not to exceed
40A.
NOTE:
Use a grounding conductor terminal
plate (fork terminal) having upturned
lugs or the equivalent to hold the wire
in position. Maximum 6 mm
2
(10
AWG) wire.
Torque Guidelines
• Properly torque line and load
terminals to 1.4 Nm (12 in-lb).
• Retorque after 48 hours to
minimize wire cold flow.
• Retorque line and load
terminals every 3 to 6 months.
