The inverter will automatically shut off under a short circuit fault. The CPU is designed to
detect short circuits and in order to avoid unnecessary tripping of the reserve (utility
supply) breaker, the static switch will remain open or inactive. (There will be no output
power present)
Listed below are all the warning conditions that can be displayed (they are arranged in
order of priority, starting with the highest priority):
