Cause
AC under-voltage
shutdown at 108 V. The
inverter has shut down to
protect the loads.
AC over-voltage
shutdown at 135 V. The
inverter has shut down to
protect the loads.
AC1 under-voltage
shutdown at the AC1 Lo
Volt setting.
AC1 over-voltage
shutdown at the AC1 Hi
Volt setting.
AC1 under-frequency
shutdown at AC1 Lo
Freq setting.
AC1 over-frequency
shutdown at the AC1 Hi
Freq setting.
AC1 under-voltage
shutdown at the AC1 Lo
Volt setting.
Solution
Clear the fault and attempt restart. If
problem persists, call customer
service.
Clear the fault and attempt restart. If
problem persists, call customer
service.
Fault clears when voltage rises
above the AC1 Lo Volt setting. If
fault persists, check AC input
voltage. Check and adjust AC input
low voltage setting.
Fault clears when voltage falls
below the AC1 Hi Volt setting. If
fault persists, check AC input
voltage. Check and adjust AC input
high voltage setting.
Fault clears when frequency rises
above the AC1 Lo Freq setting. If
fault persists, check AC input
frequency. Check and adjust AC
input low frequency setting.
Fault clears when frequency falls
below the AC1 Hi Freq setting. If
fault persists, check AC input
frequency. Check and adjust AC
input high frequency setting.
Fault clears when voltage rises
above the AC1 Lo Volt setting. If
fault persists, check AC input
voltage. Check and adjust AC input
low voltage setting.
