Connection

STUDER INNOTEC

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.

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
