Fault100
Driver
over-current
Inverter shutdown
and will restart
automatically after
the fault
disappears
1. Short circuit of
inverter output wires;
2. Hardware circuit
damage
Please check whether
there have short circuit
situation between 3
phase output wires
Fault105
Over-load
Inverter shutdown
and will restart
automatically after
the fault
disappears
The capacity of load
is higher than rated
output power of
inverter.
Please make sure the
system is proper
designed. The power of
pump motor should not
be higher than inverter
output.
Fault108
AC
over-current
Inverter shutdown
and will restart
automatically after
the fault
disappears
1. The capacity of
load is higher than
rated output power
of inverter.
2. Motor occurs
locked-rotor;
3. Pipe system
design is not
reasonable
1. Inspect pump motor;
2. Inspect pipe system

Fault112
Short-circuit
Inverter shutdown,
non-recover
malfunction. No
automatically
restart, only if
recharged
Output wire short
circuit.
1. Please check if there
is short circuit in output
wires.
2. If this happen
frequently, please
contact supplier.

inverter and pump
appear fault
Please check if the
output wires are proper
connected and fixed.
