Warranty and supply conditions
The warranty conditions are considered to be valid if the Customer
adheres to the indications in this manual; any conditions deviating from
those described herein must be expressly agreed in the purchase order.
ABB declares that the equipment complies with the provisions of law currently in force in the
country of installation and has issued the corresponding declaration of conformity.
Not included in the supply
ABB accepts no liability for failure to comply with the instructions for correct installation and
will not be held responsible for systems upstream or downstream of the equipment it has
supplied.
It is absolutely forbidden to modify the equipment. Any modication, manipulation, or alteration
not expressly agreed with the manufacturer, concerning either hardware or software, shall
result in the immediate cancellation of the warranty.
The Customer is fully liable for any modications made to the system.
Given the countless array of system congurations and installation
environments possible, it is essential to check the following: adequate
spaces, suitable for housing the equipment; airborne noise produced
based on the environment; possible ammability conditions.
ABB will NOT be held liable for defects or malfunctions arising from:
improperuseofthe equipment;deterioration resultingfrom transportation
or particular environmental conditions; performing maintenance
incorrectly or not at all; tampering or unsafe repairs; use or installation by
unqualied persons.
ABB CANNOT be held responsible for disposal of: displays, cables,
batteries, accumulators etc. The Customer shall therefore arrange for
the disposal of substances potentially harmful to the environment in
accordance with the legislation in force in the country of installation.

1- Introduction and general information
Field of use, general conditions
ABB accepts no liability for damage of any kind that may arise from incor-
rect or careless operations.
You may not use the equipment for a use that does not conform to that provided for in the
eld of use. The equipment MUST NOT be used by inexperienced staff, or even experienced
staff if carrying out operations on the equipment that fail to comply with the indications in this
manual and enclosed documentation.
Intended or allowed use
This equipment is a string inverter designed to:
transform a direct current (DC)
supplied by a photovoltaic generator (PV)
in an alternating electrical current (AC)
suitable for feeding into the public distribution network.
Limits in field of use
The inverter can be used only with photovoltaic modules which have ground isolated input
poles, unless they are accessories installed that enable grounding of the inputs. In this case
you must install an insulating transformer on the AC side of the system.
Only a photovoltaic generator can be connected in the input of the inverter (do not connect
batteries or other sources of power supply).
The inverter can be connected to the electricity grid only in countries for which it has been
certied/approved.
The inverter cannot be connected to the DC side in parallel to other inverters to convert en-
ergy from a photovoltaic generator with a power greater than the nominal power of the single
inverter.
The inverter may only be used in compliance with all its technical characteristics.
Improper or prohibited use
IT IS STRICTLY FORBIDDEN TO:
• Install the equipment in environments with particular ammability conditions or in adverse or
disallowed environmental conditions (temperature and humidity).
• Use the equipment with safety devices which are faulty or disabled.
• Use the equipment or parts of the equipment by linking it to other machines or equipment,
unless expressly provided for.
• Modify operating parameters that are not accessible to the operator and/or parts of the
equipment to vary its performance or change its insulation.
• Clean the equipment with corrosive products that may corrode parts or generate electro-
static charges.
• Use or install the appliance or parts of it without having read and understood the contents of
the user and maintenance manual.
• Warm or dry rags and clothes on parts at temperature. In addition to being hazardous, doing
so would compromise component ventilation and cooling.

General conditions
The characteristics of the equipment are described so that its main
components can be identied and the technical terminology used in the
manual can be explained.
Technical terminology and the fast information retrieval system, are
supported by:
• Table of contents
• Reference number index
The Characteristics chapter contains information about the models,
details of the equipment, characteristics and technical data, overall
dimensions and identication of the equipment itself.
The customer/Installer takes full responsibility if, when reading this manual, the chronological
order of its presentation established by the manufacturer is not observed. All information is
provided and occasional reference may be made to information in previous chapters.
In certain cases, there may be a need to separately document software
functionality or attach supplementary documentation to this manual
intended for more qualied professional gures.

2 - Characteristics
Models and range of equipment
The models of single-phase inverters covered by this manual are divided
into four groups according to their maximum output power:
2.0kW, 3.0 kW, 3.6 kW or 4.2 kW.
For inverters of equal output power the variant between the various mod-
els is the presence or lack thereof of the DC disconnect switch 16
The choice of the inverter model must be made by a qualied technician who knows about
the installation conditions, the devices that will be installed outside the inverter and possible
integration with an existing system.

2 - Characteristics
Besides the label with the specications, an additional inverter identica-
tion label is also provided.
The label displays the following information:
The ofcially required information is located on the approval label. The identication label is
an accessory label which shows the information necessary for the identication and charac-
terisation of the inverter by ABB.
Note: The labels are NOT to be hidden by foreign objects and parts (rags, boxes, equipment,
etc.); they must be regularly cleaned and always kept in sight.
