STUDER INNOTEC
When connecting the battery, there's a spark
(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 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:
Off: the 230 V voltage is NOT present in the
outlet, the inverter is off.
Illuminated: a 230 V voltage 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:
No load (stand-by)
the 230 V voltage has
AJ V2.0
AJ
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 tempe-
rature 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 equip-
ped with a stand-by system which 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 cases this
adjustment is
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
5
not necessary.
