A short circuit may be applied to the AC output continuously during inverter mode without damage
to any components. Unit will shut down within 10 seconds, and display will indicate ‘E03’ with the
buzzer beeping @ 1 Hz.
Note:
Manual reset is required to restart Inverter after AC Overload or Short Circuit shutdown.
System will automatically reset AC Overload or Short Circuit shutdown error when utility is
available. The supplemental protector or the branch protection specified in the Installation Guide
should be open under bypass short circuit output condition.
