SECTION 4 − INSTALLATION

4-1. Specifications

If the unit is operated from a 30 ampere, 115 volt circuit or a 15 ampere, 230 volt

circuit, a different input power plug must be installed on the power cord. See

Section 4-9 for instructions.

4-3. Duty Cycle And Overheating

Duty Cycle is percentage of 10 min-

utes that unit can cut at rated load

without overheating.
If unit overheats, thermostat(s)

opens, output stops, Temperature

trouble light goes On, and cooling

fan runs. Wait fifteen minutes for

unit to cool or temperature light to

go off. Reduce amperage or duty

cycle before cutting or gouging.
Y Exceeding duty cycle can

damage unit and void

warranty.
