(Danger of explosion!), because of the
charging of the internal condensator. Check
that the cables are well adjusted. 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 tension 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:
Off: the 230 V tension is NOT present in the
outlet, the inverter is off.
Illuminated: a 230 V tension is present in the
outlet, the inverter is on.
Blinking:
been cut due to an alarm; the inverter
will resume function when the failure
has disappeared (see the failure table).
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 tension will be
interrupted.
No load (standby)
the 230 V tension has
Possible failures:
Overheat: the acoustic indicator beeps 3 ºC
before
temperature reach its normal level, the
tension in the outlet is not interrupted.
Low battery tension: the indicator beeps for a
minute before the interruption. If the
tension of the battery rises, the outlet
tension 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 standby system
The AJ inverter with a power of 400 W and
more are equipped with a standby system
witch is in function when no load are
connected. In that situation the inverter is in
low power 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 case this
adjustment
adjustment is made with a small screw driver
in the hole marked standby. This adjustment
is made with a small screw driver in the hole
marked standby. 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 standby mode when you remove the
load. If not, this mean that the load is too
small to be detected.
If the standby is not required, turn the Knob
fully to the right.
