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
certied/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.
