IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety instructions that must be followed during installation
and maintenance of the equipment.
SAVE THESE INSTRUCTIONS!
This manual must be considered as an integral part of the equipment, and must be available
at all times to everyone who interacts with the equipment.
The manual must always accompany the equipment, even when it is transferred to another user.
Operators are required to read this manual and scrupulously follow the indications reported
in it, since ABB cannot be held responsible for damages caused to people and/or things, or
the equipment, if the warranty conditions are not observed.

Warranty and Supply Conditions
The warranty conditions are described in a special certicate supplied
with the equipment. Furthermore, 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.
The equipment complies with the pertinent legislation currently in force in the country of in-
stallation and it 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 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 re-
sult 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 envi-
ronments possible, it is essential to check the following: sufcient space
suitable for housing the equipment; airborne noise produced depending
on the environment; potential ammability hazards.
ABB will NOT be held liable for defects or malfunctions arising from: im-
proper use of the equipment; deterioration resulting from transportation
or particular environmental conditions; performing maintenance incor-
rectly or not at all; tampering or unsafe repairs; use or installation by
unqualied persons.
ABB will NOT be held responsible for the disposal of: displays, cables,
batteries, accumulators etc. The Customer shall therefore arrange for the
disposal of substances potentially harmful to the environment in accor-
dance with the legislation in force in the country of installation.

ted skills and knowledge on the structure and operation of the unit may install the inverter.
The installation must be performed by qualied installers and/or licensed electricians in ac-
cordance with the existing regulations in the country of installation.
The employment of a person who is NOT qualied, is drunk, or on narcotics, is strictly forbid-
den.
The customer has civil liability for the qualication and mental or physical state of the profes-
sional gures who interact with the equipment. They must always use the personal protective
equipment required by the laws of the country of destination and whatever is provided by their
employer.

1- Introduction and general information
Field of use, general conditions
ABB shall not be liable for any damages whatsoever that may result from
incorrect 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 inverter designed for:
transforming a continuous electrical current (DC)
supplied by a photovoltaic generator (FV)
in an alternating electrical current (AC)
suitable for feeding into the public distribution grid.
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 earthing 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 ener-
gy 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 subject to particular conditions of ammability 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 isolation.
• Clean with corrosive products that could eat into parts of the equipment or generate elec-
trostatic charges.
• Use or install the appliance or parts of it without having read and understood the contents of
the user and maintenance manual.
• Heat or dry rags and clothing on the parts in temperature. In addition to being hazardous,
doing so would compromise component ventilation and cooling.

General conditions
A description of the characteristics of the equipment is given so as to
identify its main components and specify the technical terminology used
in the manual.
Technical terminology and the fast retrieval system for information, are
supported by:
• Contents
• Reference number index
The Characteristics chapter contains information about the models, de-
tails of the equipment, characteristics and technical data, overall dimen-
sions 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 considering occasional inclusion of that provided in previous chapters.
In certain cases, there may be a need to separately document software
functionality or attach supplementary documentation to this manual in-
tended for more qualied professionals.

2 - Characteristics
Models and range of equipment
The specic models of three-phase inverters that this manual is about
are divided into two groups according to the maximum output power:
20kW or 27.6 kW.
For inverters of equal output power, the variant between the various
models is the layout of the wiring box 02 .
The choice of model of inverter 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
In addition to the label showing the specications of the inverter, there
are two part identication labels for the inverter and wiring box.
These labels list 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 cha-
racterisation of the inverter by ABB.
If the service password is required, please use the details shown on the top label (inverter)
N.B. The labels must NOT be hidden with objects and extraneous parts (rags, boxes, equip-
ment, etc.); they must be cleaned regularly and kept visible at all times.
