Load/Temperature Related Errors/Faults:

Over Temperature ** FAULT ** In this mode, most power circuits should be off, thus lowering the

temperature. Once in Fault Bypass mode, if the temperature exceeds the

overtemperature threshold for 5 minutes, the unit will go to latched idle.

Overload ** FAULT ** The unit should automatically revert from fault bypass mode to ECO/Online

(overload release) when the load is reduced to less than 95% consistently

for 10 seconds.
