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.
