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.

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.

1- Introduction and general information
The document and who it is for
Purpose and structure of the document
This operating and maintenance manual is a useful guide that will enable
you to work safely and carry out the operations necessary for keeping the
equipment in good working order.
If the equipment is used in a manner not specied in the installer manual, the protection pro-
vided by the equipment may be impaired.
The language in which the document was originally written is ITALIAN; therefore, in the event of
inconsistencies or doubts please ask the manufacturer for the original document.
List of annexes
In addition to this operating and maintenance manual, (if applicable or on
request) the following enclosed documentation is supplied:
- EC declaration of conformity
- quick installation guide
- warranty
WARNING: Part of the information given in this document is taken from the original docu-
ments of the suppliers. This document contains only the information considered necessary
for the use and routine maintenance of the equipment.
Staff characteristics
The customer must make sure that the operator has the necessary skill and training to do his/
her job. Personnel in charge of using and maintaining the equipment must be expert, aware
and skilled for the described tasks and must reliably demonstrate their capacity to correctly
interpret what is described in the manual.
For safety reasons, only a qualied electrician who has received training and/or demonstra-
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.
