Introduction
The sinewave inverters of the AJ series have
been designed to meet industrial and
domestic needs. They fulfil the highest
requirements of comfort, safety and reliability.
Any device designed for the public electrical
network of 230 V 50 Hz can be connected to
them (up to the nominal power of the
inverter).
The AJ series is the perfect source of tension
in any place where the public network is not
available.
This document is an essential part of the
inverter and must always be carried with it
and be at the disposition of anyone working
on the installation.
Should you have any doubt or question, do
not hesitate to contact your specialist
salesperson who will give you the best
advice.
Note
A deficient assembly could result in damage
to the device, cause function failures or
potential damage to the users.
The working device generates a high tension
which might be fatal in case of contact. So,
any manipulation of the inverter must be
carried out with utmost care.
THE OWNER MUST NOT MANIPULATE
ANY PIECE INSIDE THE INVERTER.
Opening the inverter or using it incorrectly will
result in the immediate loss of the warranty.
No current or tension generating devices
(public grid, generator, ...) may be connected
to the outlet of the inverter because this could
result in its destruction.
The inverter AJ is to be used only with a lead
battery. As for the usage of batteries, follow
the manufacturer’s instructions.
Installation
The AJ sinewave inverter is an electronic
device, for which some caution must be taken
when installing it:
Place where the inverter is to be installed :
- Out of reach of unauthorised persons,
specially children.
- In a dry place (max. 95% humidity), and in
any case with no condensation.
- Not directly on top of the batteries.
- Ventilation must be free, and a space of 10
cm. on each side is needed for good
evacuation of the internal heat.
Fitting the inverter
The inverter is fitted by screws (max. 4mm
for AJ 200-AJ 800 or max. 8mm for AJ 2000)
using the four holes provided. The fitting
screws are not supplied with the inverter.
It may be fit into any position.

Connection
The connection of the inverter should be
done with utmost care. First connect the
consumer devices so as to prevent any
further contact once the 230 V tension is
present. The technical data and connection’s
description, is either under one side of the
inverter or onto the cable connection side.
Installation is to be made only with authorised
persons.
Connecting the consumer devices
The AJ inverter is supplied with a 230 V cable
for the consumer devices. This connection
must be done observing the colours:
Yellow-green: earth
Brown: phase
Blue: neutral
Once the consumer devices are connected,
make sure that they are turned off before
connecting the battery
Note
An Inverter constitutes an independent power
supply from net and could be considered in
the same way as a generator set. The phase
and the neutral are not differentiate. The
tension in between the phase and the neutral
is 230V. An appropriate divisor establishes a
115V tension in between neutral and earth,
and the phase and earth. According to the
local prescriptions or particular requirement,
(example: use of a ground fault detector) a
true neutral may be established by
connecting the neutral and the earth wire
together. The so connected point, may be
connected with an existing earth: earth of
building; the chassis of vehicle or the hull of
ship.
Equivalent schema
Connecting the battery
Once the consumer devices are connected,
make sure that the installations instructions of
the 230V has been followed with utmost care
before connecting the battery.
The cable of the battery is supplied with the
inverter and already connected in it.
A fuse must be installed on the battery.
Connect the battery observing carefully the
polarity. The AJ inverter, except 2000W/12V,
is protected against inversion by a fuse, but if
the polarity should be inverted, the inverter
must be sent to the manufacturer for control.
Connect the battery using the following
colours:
BLACK cable: negative pole (-)
RED cable: positive pole (+)
For AJ 200, dominant colour is applicable

(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.
Use
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:
No load (standby)
the 230 V tension has
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.
Possible failures:
Overheat: the acoustic indicator beeps 3 ºC
before cutting the tension. If the
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 wi th 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 is not necessary. This
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.
6
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 tension is
intermittently present at the output
7
Safety
The inverter is electronically protected. But protection against polarity inversions of the battery
occurs with an internal fuse, except for 2000W/12V inverter, which has no fuse. The following
table will show you the different failures and their consequences.
FAILURE CONSEQUENCE SOLUTION
Low battery tension
Voltage < 1.8V/cel
Inverter momentarily
stopped, the green
indicator blinks.
Automatic restart when the battery tension
rises
Deep discharged battery
(voltage <1,5V/cel)
Inverter stopped Inverter should be manually restarted

Maintenance
The inverters of the AJ series do not need any
special maintenance. The casing may be
cleaned with a damp cloth (not wet).
In the case of malfunction, the inverter should
be sent back to the manufacturer for control in
its original packing.
Before sending the inverter, check the table
above.
The battery is loaded and is in accordance to
the inlet nominal tension of the device.
The consumer devices do not have any defects
or overload for the inverter.
Should you contact your salesperson, note the
following points before calling:
(you will find this information on the label
underneath the inverter)
- Series number
- Power of the inverter
- Inlet nominal tension of the inverter
So you will have quick and efficient help to
solve your problem.
