TROUBLE / SYMPTOMS POSSIBLE CAUSE(S) SUGGESTED REMEDIES
NO AC OUTPUT
On the inverter
• Green LED on the front panel of the
inverter is oN
• Red LED is OFF
• Buzzer alarm is OFF
• Yellow LED is ON
On the Remote Control SSW-R1-12B
(For SSW-1000-1500-2000-12A)
• DC input voltage is being displayed and
has risen to High DC Input Voltage Shut-
down Threshold of 15.3V +/- 0.3V
• Message “Input Fault” is flashing
• Power Bar Graph is OFF
• LCD is dimmed
Shutdown due to high DC input voltage
DC input voltage has risen to High DC Input
Voltage Shutdown Threshold of 15.3V +/- 0.3V 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 Thresh-
old 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 perma-
nently damage the inverter
INVERTER DOES NOT SHUT DOWN
WHEN REMOTE CONTROL SSW-R1-12B IS
SWITCHED OFF
(For SSW-1000-1500-2000-12A) The ON / OFF switch on the inverter is
in ON condition When using the remote Control SSW-r1-12b,
ensure that the oN / off switch on the inverter
is in off position
MOTORIZED POWER TOOL
WILL NOT START excessive start-up current from the load is acti-
vating the Soft Start Circuit and is reducing 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 proportional to
Voltage and the Current) If appliance does not start, then the appliance
is drawing excessive power and will not work
with the inverter
MOTORIZED POWER TOOL DOES
NOT OPERATE AT CORRECT SPEED Purely inductive load with higher reactive
power and lower Power factor is activating the
soft start circuitry and reducing the output volt-
age resulting in reduced speed 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
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.
