3-2. 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, and cooling
fan runs. Wait fifteen minutes for
unit to cool. Reduce amperage or
duty cycle before cutting.
Y Exceeding duty cycle can
damage unit and void war-
ranty.
