IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety instructions that must be followed during the installa-
tion and maintenance of the equipment.
SAVE THESE INSTRUCTIONS!
Keep this document in a safe place near the inverter for easy access during installation, op-
eration and maintenance.
THE INSTALLER MUST READ THIS DOCUMENT IN ITS ENTIRETY BEFORE INSTALLING
THIS EQUIPMENT.
Operators are required to read this manual and scrupulously follow the instructions given in it,
since FIMER cannot be held responsible for damage caused to people and/or things, or the
equipment, if the conditions described below are not observed.
The purpose of this document is to support the qualied technician, who has received training
and/or has demonstrated skills and knowledge in construction, to install, operate and maintain
the inverter. This manual covers only inverter, not any equipment (photovoltaic modules, external
disconnects, etc) to which it is connected.
Warranty requirements are included in the Terms and Conditions of sale included with the
inverter order.
NOTE: Any changes not approved by FIMER void the warranty.

1- Introduction and general information
Field of use, general conditions
FIMER 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 (PV)
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.

box. The label displays the following information:
The Communication Identication label is divided in two separate parts by a dashed line; take
the bottom part and apply it on the plant documentation. (it’s recommend to create a plant
map and apply the Communication Identication label of each inverters in the right position
of that map).
