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 V
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.

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.
System Wiring Example
Alternative Latching Alarm Circuit
If there is a need for a latching alarm in the case of an open heater or
shorted SCR, the DIN-A-MITE alarm circuit could be used as shown in
the latching alarm example at right. 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 set can be used for alarm signaling.
