6. PROTECTIONS
6.1 Pre-warning (buzzer)
If the input voltage is becoming low, the inverter will emit an acoustic signal as a warning.
6.2 Low voltage protection.
If, after the pre-warning, the input voltage still drops further, the low voltage protection will
eventually take effect. The 230VAC output is shut down and the red indicator ‘fault’ will light.
The buzzer will also continue to sound.
If the input voltage has risen again sufficiently, the inverter will automatically restart.
6.3 Over voltage protection
If the input voltage rises too high, the overvoltage protection will come into effect. The 230VAC
output is shut down and the red ‘fault’ LED lights up. If the input voltage has dropped sufficiently,
the inverter will automatically restart.
