Do not connect or disconnect any wiring on the inverter as bodily harm and /
or damage to the equipment may result.
When momentary power loss is greater than 2 seconds (the higher the HP
rating, the longer the time), the inverter can not sustain power to the control
circuit. Therefore, when power is restored, the operation of the inverter is
based on the setup of b000 / A015 and the condition of the external switches.
This is considered to be a restart.
When restarting, the operation of the inverter is based on the setup of
b000 and A015 and the condition of external switch (FWD / REV button).
NOTE: the start operation is not affected by parameters
A013/A014/A018/A019.
1. When b000=0000, the inverter will not run after restart.
2. When b000=0001 and the external (FWD / REV) switch is off, the
inverter will not run after restart.
3. When b000=0001, the external switch (FWD / REV button) is on, and
A015=0000, the inverter will run automatically after restart. In this case
after loss of power, turn off the external (FWD/REV) switch to avoid
damage to the equipment and injury to personnel after sudden
restoration of power.
For further information, please refer to the description and warnings of
parameter A015 covered in the advanced parameter section.
When the momentary power loss is less than 2 seconds, the inverter still has
enough storage power to support the control the circuit. Therefore, when
power is restored, the inverter will automatically restart depending on the setup
of A013 / A014.
Below situations are normal:
1. The inverter display will flash the AC input voltage for 1 second after power is applied.
2. After power is off, the inverter display will flash "LV" for 1 second when the inverter
is at Stop status and the inverter display will flash "LV-C" for 1 second when the
inverter is at Run status.
