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
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. An appropriate divisor
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 - geeen 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,
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 bicolor cable
is used. Go for the dominant colour.
When connecting the battery, there is a spark
