FUSE REPLACEMENT

FUSES INSIDE THE INVERTER
The AC side of this inverter is protected by an integral electronic overload circuit and will automatically reset in
some cases.
More than that, this inverter is equipped with a DC side fuses that are located inside the inverter. Normally,
these fuses will not blow unless a serious problem occurs.
Please Do NoT replace the fuses yourself. We recommend you contact technician to find and fix the problems.
High voltage and high temperature inside!
CAUTION: NO USER-SERVICEABLE COMPONENTS INSIDE. DO NOT ATTEMPT TO OPEN THE INVERTER.

POSSIBLE CAUSE(S)
Shutdown due to high DC input voltage
DC input voltage has risen to High DC Input
Voltage Shutdown Threshold of 15.3V +/- 0.3V
The ON / OFF switch on the inverter is
in ON condition
excessive start-up current from the load is
activating the Soft Start Circuit and is reduc-
ing the output voltage and consequently the
current to a level where the starting torque
required by the motor is not sufficient to turn
the motor. (Starting torque in a motor is pro-
portional to Voltage and the Current)
Purely inductive load with higher reactive
power and lower Power factor is activating
the soft start circuitry and reducing the output
voltage resulting in reduced speed
SUGGESTED REMEDIES
1. Switch off the AC load and the inverter.
2. Disconnect the DC input to the inverter
3. Check the output voltages of the battery
and charging source and ensure these are
below the High DC Input Voltage Shutdown
Threshold of 15.3V +/- 0.3V
4. Check that a 24V battery is not being used
instead of 12V battery
5. The unit will reset automatically once the
voltage drops to 14.9V +/- 0.2V
6. CAUTION! Voltage input of > 16 V will
permanently damage the inverter
When using the remote Control SSW-r1-12b,
ensure that the oN / off switch on the
inverter
is in off position
If appliance does not start, then the appliance
is drawing excessive power and will not work
with the inverter
Make the load not purely inductive. operate
an incandescent lamp at the same time as the
motor. This will reduce the reactive power and
raise the Power factor so that the Soft Start
Circuit is not activated
