When connecting the battery, there is a spark
(Danger of explosion!), because of the
charging of the internal filtering capacitors.
Check that the cables are well adjusted
and well tightened.
As long as it is possible, do not extend the
cables supplied with the batteries. Extending
them may increase the losses and cause
malfunction of the inverter.
Once the inverter is connected to the
batteries, a 230 V voltage is present in the
outlet of the inverter.

Control and indicators
Control switch on/off
There is a switch on the inverter to activate or
deactivate it. Use this function to save the
energy of the batteries when you are not using
the inverter.
Green indicator
A green light on the inverter indicates its
function mode:
Illuminated: a 230 V voltage is present in the
outlet, the inverter is on.
Blinking:
_ _ _ : No load (stand-by)
__ __ __ : the 230 V voltage has been cut
due to an alarm; the inverter will resume
function when the failure has disappeared
(see the failure table).
Off: the 230 V voltage is NOT present in the
outlet, the inverter is off.
Acoustic indicator
The AJ inverter has an acoustic indicator for
the following instances:
Intermittent beep: there is a failure in the
inverter and the outlet voltage will be
interrupted.
Possible failures:
Overheat: the acoustic indicator beeps 3 ºC
before cutting the tension. If the temperature
reaches its normal level, the voltage in the
outlet is not interrupted.
Low battery voltage: the indicator beeps for a
minute before the interruption. If the voltage
of the battery rises, the outlet voltage is not
interrupted.
Continuous beep for two seconds: you have
pressed the ON/OFF switch to restart the
inverter. The tension in the outlet will be
immediately present after the acoustic signal.
Model with stand-by system
The inverters from the AJ 500-12 are
equipped with a stand-by system which is in
function when no load is connected. In that
situation
the
consumption mode.
The output tension is not continuously present
and the LED is blinking as long as no load is
detected.
The minimal load detected can be adjusted
between 1 and 20 W. In most cases this
adjustment
adjustment is made with a small screw driver
in the hole marked stand-by. This adjustment
is made with a small screw driver in the hole
marked stand-by. Adjusting the switching-on
level is as follows: Switch off all consuming
devices; turn the Turning Knob to the Left
(counter-clockwise)until the LED is blinking,
switch ON the smallest consuming device (i.e.
Mobile phone charger); turn the Turning Knob
slowly to the right until LED is lit continuously.
Check that the inverter will go back in stand-
by mode when you remove the load. If not,
this means that the load is too small to be
detected.
If the stand-by is not required, turn the Knob
fully to the right.
In the full counter clockwise position, the
sensibility is minimal (20 W). Do not push on
the screw driver.
NOTE: in this mode the output voltage is
intermittently present at the output
