ONNECTION
The connection of the inverter should be done
with utmost care for a good operation of the
system. The technical data and connection's
description are either under one side of the
inverter or onto the cable connection side. First
connect the consumer devices and install a
plug so as to prevent any further contact once
the 230 V voltage is present.
Installation is to be made only by authorized
persons.

ONNECTING THE CONSUMER DEVICES
The AJ is supplied with a 230 V cable to be
connected to the consumer devices. This
connection must be done observing the
following 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 a voltage source
independent from the grid and could be
considered in the same way as a generator set.
The voltage in between the phase and the
neutral is 230V.
establishes a 115V voltage in between neutral
and earth, and between the phase and earth.
According to the
particular requirement, (example: use of a
ground fault detector) a true neutral may be
established by connecting the neutral and the
earth wire together (yellow - green and blue).

ONNECTING 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 battery cables are supplied with the
inverter and already connected in it.
Connect the battery observing carefully the
polarity.
The AJ inverter, except AJ 2100-12, is protected
against reverse polarity by a fuse, but should
the polarity be reversed, 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 275-12 (-S) to 700-48 (-S), a bicoloured
cable is used. Go for the dominant colour.

A fire security fuse must be installed on the
battery.
