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 2
WARNING: Wiring examples show L2 in
phase-to-phase, 200VÅ (ac) and above
configuration. In phase-to-neutral, 100 VÅ
(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 3
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.
Ó 4
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.
