• Connect the other end of the positive DC input cable to one of the terminals of the
Disconnect Switch.
• Connect a DC input cable between the other terminal of the Disconnect Switch and one
side of the terminal of the fuse holder.
• Connect a DC input cable between the other terminal of the fuse holder and the battery
positive terminal.
• Install the selected fuse to the fuse holder.
• Turn Disconnect Switch to ON position.
Remote Switch (optional) Connection:
• The unit comes with a Remote port and an optional Modul-System ’Remote Switch’
accessory (21000-03) can be used to turn unit On and OFF remotely. To install the
‘Remote Switch’, just connect the switch’s RJ12 plug to the RJ12 ‘Remote’ port located at
the Front AC panel of the Power inverter. Please note polarity when connecting the plug.
• The Power ‘On/Off’push button on the remote shares the same function as the green
‘On/Off’ button on the main unit.
• With ‘Power Save’ Function set to OFF (default), the ‘Power’ indicator will remain solid ON
when AC Output Power is available and will be OFF when the unit has shutdown.
• With ‘Power Save’ Function set to ON, the ‘Power’ indicator will be flashing when AC
Output Power is available and will be OFF when the unit has shutdown.
• Please note that the Modul-System Power Inverter will not work with the digital
wiring and control system Modul-Connect with the ‘Power Save’ Function set to ON.
Use of the Ignition Start Function on unit:
• An ‘Ignition Start’ port is located at the Front AC Panel of the unit using a 6.3mm width
female spade terminal. This port is used for turning the unit ON and OFF using a +12V
signal. An insulated female connector is required to connect to the port.
• Connecting to +12V will turn ON the unit and removing the +12V signal will turn it OFF.
• This +12V connection should be fused at its source with a minimum 2A fuse.
Power Inverter Test after installation:
• Press and hold the green ‘On/Off’ button on the unit to turn ON the unit.
• Check that the ‘Status’ indicator turns to solid green.
• Plug in a small AC load like a 40W table lamp or small appliance to the AC socket to verify
AC is available.
• The unit is successfully installed and functioning properly.
4. UNIT OPERATION
WARNING: RISK OF EQUIPMENT DAMAGE
Do not connect an AC power source like utility power or generator to the AC outlets of the unit.
Turn ON and OFF the unit
• Press and hold the green ‘On/Off’ button for about a second to turn ON the unit and
‘Status’ indicator will turn on.
• Press again the green ‘On/Off’ button to turn OFF the unit and the ‘Status’ indicator will
turn off.
Understanding the ‘Power Save’ function
The unit can pre-set with ‘Power Save’ function ON or OFF. If unit is turned ON with ‘Power
Save’ function pre-set to ON, with >10W AC load connected to the unit, the unit will provide
continuous AC Output and with <10W AC Load connected to the unit or with AC Load
changing from >10W to < 5W, the AC Output will change from continuous to pulsing AC
Output every 5 seconds.
The unit is default set to ‘Power Save’ OFF. To change the ‘Power Save’ function from OFF
to ON or switch back from ON to OFF, press and hold the green ‘On/Off’button for more
than 5 second until the ‘Status’ light quickly flashes three times and the alarm beeps for
more than 2 seconds.

manual
Understanding the Warning and Shutdown Condition
Over Temperature Warning: Unit internal temperature is high. Unit requires better
ventilation.
DC Over Voltage Warning: DC Input Voltage is high and close to the over-voltage
shutdown limit. Checking the battery voltage.
DC Under Voltage Warning: DC Input Voltage is low and is close to the under-voltage
shutdown limit. Checking on battery voltage or battery connection is required.
Over Temperature Shutdown: Reduce the AC load and provide more ventilation to the unit.
Unit will automatically restart when the internal temperature of the unit cools down.
DC Over Voltage Shutdown / DC Under Voltage Shutdown: Check the battery voltage in
the first 30 seconds, AC Output will resume when battery voltage is corrected to be within
the unit’s operating range. If the battery voltage shutdown condition is ignored, the unit will
latch OFF completely after 30 seconds and restart the unit using green ‘On/Off’button is
required after the battery voltage is corrected.
AC Output Overload Shutdown: Check AC Load connected to the unit. AC Output is short
circuited or AC Power draw by the load is beyond the unit’s limit. The indicator and alarm
will beep for about 30 seconds before it is latched OFF completely. Restarting the unit
using the green ‘On/Off’button is required after the AC Load condition is corrected.
USB Port on unit
With unit on, 2.1A 5V USB is provided on the 5V USB port. This can be used to charge 5V
USB Powered devices.
Understanding the Fan Operation
The fan on the unit is internal temperature activated. It will automatically turn on when AC
output power exceeds the pre-set values (~ 200W) and turn off when AC output power is
reduced to 150W. It will also automatically turn on when it senses the internal components
have reached to around 80°C and turn off when temperature drops to below 60°C.
AC Load on Power Inverter
Although the Power Inverter can provide high surge power (up to two times the rated output
power), some appliances may still trigger on the unit protection system during start up or
surge period. A higher power inverter is required for those appliances.
Estimated Run time on Load
Following run time is an estimate based on using a 12V-120AH battery bank. Actual runtime
may vary.
Small Freezer (8.8 cu. ft.)
Not applicable (start-up surge too high)
