GROUNDING AND CONNECTABLE APPLIANCES
To ensure maximum safety is necessary to ground the inverter’s metal casing. To this end, the power inver-
ter is equipped with a grounding terminal on the back panel.
Note
. The negative terminal of the battery must be grounded (see EN50272-2).
Note
. Grounding must be performed in a workmanlike manner in accordance with local regulations. For this
reason, it is better to entrust the inverter installation to qualified service personnel.
If the electrical device to be connected is a
Class II
device, that is, a device with double insulation and without the
ground connection, you can connect it to the inverter without further arrangements. These devices usually have a
two-pin plug and the symbol of double insulation on the product data plate / label.
If the electrical device to be connected is a
Class I
device
,
that is, a device with single insulation and ground
conductor, to guarantee the maximum safety it is mandatory to execute the device’s grounding in accordance
with the current regulations. It is reccomended to entrust the installation of grounding to specialized technical
personnel.
Note.
The ground terminal of the inverter output socket is not connected to the inverter’s metal casing.
Hence, the simple grounding of the inverter casing is not enough to execute the grounding of the appliance.
POWER INVERTER OPERATION
To ensure the maximum safety and reliability, after performing the grounding as described in section
GROUN-
DING AND CONNECTABLE APPLIANCES
, it is advisable to first connect the inverter to the battery, after tur
-
ning on the inverter, after still connect your electrical device and turn it on by following the instructions below.
1. Connect red cord to the red input terminal, positive pole (+)
2
. Connect the eyelet of black cord to the
black input terminal, negative pole (-)
4
. Do not reverse the polarity, it risks to damage the inverter.
2. Connect the red cord to the positive pole (+) of the battery. Connect the black cord to the negative pole
(-) of the battery. Do not reverse the polarity, it risks to damage the inverter.
3. Turn on the inverter through the ON/OFF switch . If there are not malfunctions the green LED
5
is
on and the red LED
6
is off.
4. Connect your appliance to the inverter output socket .
5. Turn on the appliance.
Note.
Do not connect or disconnect the inverter from the battery when it is on, that is, when the inverter
switch is on the ON position.
Note.
In addition to the ON/OFF switch,
the power inverter can be turned on and off through the remote
control, connectable to the specific port
9
on the front panel. This accessory is optinal, see page 10.

CABLES EXTENSION
In general, the elongation of the cables between the battery and the input of the power inverter may cause a
voltage drop with the consequent reduction of the power that the inverter can supply. When necessary, it is
advisable only to lengthen the cable (or the cables) connecting the inverter and the appliance. In any case it is
forbidden to cut, alter or tamper with the input cigarette lighter plug, otherwise the loss of any wuarranty claim.
When it is necessary to use longer connections between the battery and the inverter, use high-quality cables
with the characteristics shown in the table below.

PROTECTION FUNCTIONS
If the red LED
6
turns on when switching on the inverter or the appliance, it means that a malfunction oc-
curred and the inverter activated one or more protection functions. In this case, it is necessary to turn off the
inverter, disconnect it from the batteries and disconnect the appliance from the inverter. Before reconnecting
the inverter and your device make sure you have fixed the problems that caused the entry into operation of
protections. Refer to
Table 1
for verification and troubleshooting of common problems.
The inverter is also equipped with a buzzer that emits an acousting signal when the input voltage is lower than
10.5V DC (
IRSxxxx-12
), or 21V DC (
IRSxxxx-24
).
The power inverter is equipped with the following protections that, in case of malfunctions, shut down the 220V
AC output.
•
Input low voltage: this protection is activated when the input voltage is less than 9.5V DC (
IRSxxxx-12
),
19V DC (
IRSxxxx-24
).
•
Input overvoltage: this protection is activated when the input voltage is greater than 15V DC (
IRSxxxx-12
),
30V DC (
IRSxxxx-24
).
•
Output overload: this protection is activated when the demanded output power is greater than 1000W
(
IRS1000-xx
), 1500W (
IRS1500-xx
).
•
Temporary input short-circuit: this protection is activated when the input terminals are short-circuited. To
avoid hazards and inverter damages, remove the short-circuit quickly.
•
Temporary output short-circuit: this protection is activated when the output socket is short-circuited. To
avoid hazards and inverter damages, remove the short-circuit quickly.
•
Over temperature: this protection is activated when the inverter’s electronics circuits are overheated. This
protection also activates the acustic allarm (buzzer).
Note.
An excessive internal temperature of the inverter may be caused by its exposure to sun, or its placement
in a place that prevents effective ventilation.
VENTILATION
To allow an effective outflow of the emitted heat
the power inverter must be positioned such that
the cooling fan can properly performs its action.
