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

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.
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
When connecting the battery, there's a spark
