4-2. Duty Cycle And Overheating
Three-Phase Input Power:
60% Duty Cycle
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, and cooling fan runs. Wait fifteen minutes for unit to cool. Reduce amperage or duty cycle before cutting.
YExceeding duty cycle can damage unit and void war- ranty.
