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.

WARNING:
Wiring examples show L2
in phase-to-phase, 200 VÅ
(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.

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.
NOTE: If you plan to wire
multiple DIN-A-MITE
alarm outputs, you need
to include an intermediate
relay for each DIN-A-MITE
used.
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.

Alternative Latching Alarm Circuit
If there is a need for a latching alarm, the DIN-A-MITE alarm circuit
could be used as shown at right in the latching alarm example. If the
DIN-A-MITE triac alarm output energizes, it will energize the RY1
(external alarm relay) mechanical relay coil. Once the RY1 coil is
energized it will latch on (via the RY1A normally open contact) until the
power to the relay is removed. You could cycle the power via a reset
switch. The RY1B contact can be used for alarm signaling.
