The unit will self-reset when the fault conditions marked with an asterisk are remedied. The
MP2000E will automatically return to LINE mode if the line is qualified or BATTERY mode if it
is not. For the other faults, the unit is reset by shutting it down and restarting, using AC &
battery breakers. The faults can also be reset in the CONTROL menu of the LCD display.
Note: When the unit has a fault and line power is qualified and available, the
output loads are directly connected to the Input line with no line conditioning
or backup power provided.
