Manual

Input Voltage
The input voltage limits are shown in the following table.
Operating condition Voltage range Comments
Normal 11.0V – 14.0V –
Peak performance 13.0V – 14.0V –
Low voltage alarm 10.5±0.3V The audible low battery alarm sounds.
Low voltage shutdown 10.0±0.3V The unit shuts down to protect the battery from
being over-discharged.
High voltage shutdown Voltage is 15.5V The unit shuts down to protect itself from excessive
or more input voltage. Note: Although this incorporates
over-voltage protection, it can still be damaged
if input voltage exceeds 16V.
Unit restarts after low 11.6±0.3V The unit will not restart unless the battery voltage is
voltage shutdown acceptable for running the load.
REMOTE CONTROL
An optional remote can be purchased for the PW600, PW900 and PW1800,
P/No. PWREMOTE.
To install the remote control, insert the plug into the data socket on the
front panel.
The remote has the ability to turn the inverter on and off remotely and indicate
when the inverter is on.
TROUBLE SHOOTING
Problem Possible Cause Solution
LUP Poor DC wiring and/or poor Use proper cable and make secure
battery condition connections. Charge the battery or
install a new battery.
OUP Over-voltage(high input) shutdown Make sure the inverter is connected
to a 12V battery.
OLP Overload shutdown Reduce the load within the inverter’s
continuous power rating.
OCP Over-temperature shutdown Improve ventilation and make sure
the inverter’s ventilation openings
are not obstructed. Reduce the
ambient temperature, if possible.
OPP Short circuit Check the AC wiring for a short
circuit.
No output voltage;
no voltage

The unit is off Turn the inverter on.
No power to the inverter Check wiring to the inverter.
Inverter fuse is open Have a qualified service technician
check and replace the fuse if
necessary.
Reverse DC polarity Have a qualified service technician
check and replace the fuse, making
sure to observe correct polarity.
