4-2. Duty Cycle and Overheating

208 Volts AC Three-Phase Input Power:

40% Duty Cycle

Duty Cycle is percentage of 10 minutes that unit can cut at rated load without overheating.

If unit overheats, output stops, and cooling fan runs. Wait fifteen min- utes for unit to cool. Reduce amper- age or duty cycle before cutting.

YExceeding duty cycle can damage unit and void war- ranty.
