English description

Introduction

The sine wave inverters of the AJ series have been designed to meet industrial and domestic needs. They meet 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 voltage 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.

Warning

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 voltage which might be lethal 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 device (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 use of batteries, follow the manufacturer’s instructions.

Installation

The AJ sine wave 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 275-AJ 1300 or max. 8mm for AJ 2100 and 2400) 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 voltage 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 by 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 the grid and could be considered in the same way as a generator set. The phase and the neutral are not differentiated. The voltage in between the phase and the

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 AJ 2100-12, 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 (-)

neutral is 230V. An appropriate divisor establishes a 115V voltage 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.

RED cable: positive pole (+)

For AJ 275-400, dominant colour is applicable

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 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.

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:

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 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 not necessary. This 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 (counterclockwise)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
