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:
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:
The shorted SCR alarm
option is not available with
phase angle units.

Torque Guidelines

• Properly torque line and
load terminals to 2.7 Nm (24
in-lb).

• Retorque after 48 hours to
minimize wire cold flow.

• Retorque line and load
terminals every 3 to 6
months.
