5. Installation
5.1 Installation safety instruction
WARNING –
B
The inverter panels/covers can be removed from authorized service personnel only (the users are not authorized to
remove inverter panels/covers).
WARNING –
B
When the photovoltaic panels are exposed to sunlight they provide continuous DC voltage to the inverter. Before
installation may begin, photovoltaic panels must be shaded or isolated.
WARNING –
B
In case PVS-100/120 PRE-CHARGE BOARD KIT is installed on the inverter, it is important to remark the presence
of auxiliary power supply connected to the AC grid. In this case the inverter is supplied either by DC and AC power, so hazardous
internal voltages are present even in case the DC switches are open.
WARNING –
B
The installation must be carried out with the equipment disconnected from any voltage sources. Refer to
total de-energization and safe access”
paragraph on this manual to know all the necessary step to safely operate on the inverter.
ATTENTION –
A
This device is intended to be installed in a suitable plant for its use and its purpose. All the installation instruction
described in this chapter must be followed considering the plant structure where the device is intended to be installed. Its performance
therefore depends on the correctness of the installation.
ATTENTION –
A
It is mandatory to adhere to the indications provided in this manual, the diagrams and the enclosed documentation,
paying attention to follow the installation sequence exactly as described in this manual.
ATTENTION –
A
Staff authorised to carry out the installation must be specialised and experienced in this job. They must also have
received suitable training on equipment of this type. The installation must be performed by qualified installers and/or licensed
electricians in accordance with the existing regulations in the country of installation.
ATTENTION –
A
Handling and installation operations shall be performed only by using the special tools and accessories provided
with “PVS Installation Kit” that have to be ordered separately. The use of these equipment are mandatory to safely install the inverter.
Refer to
“Kit of recommended spare parts”
paragraph for further information.
ATTENTION –
A
The local electrical utility (or authority having jurisdiction) must approve the equipment installation before it is
connected to the electrical grid.
5.2 Installation site and position
5.2.1 General recommendation on installation
position
ATTENTION –
A
Please refer to the warranty terms and
conditions to evaluate any possible warranty exclusions due
to improper installation.
• Refer to
paragraph to check the required
environmental conditions (protection rating, temperature,
humidity, altitude, etc.).
• The installation location shall be easily accessible.
• Installation of the unit in a location exposed to direct sunlight
is NOT acceptable. (Add awning in case of direct sunlight
installation).
• Final installation of the device must not compromise access to
any disconnection devices that may be located externally.
• Do not install in small closed rooms where air cannot circulate
freely.
• Always ensure that the flow of air around the inverter is not
blocked so as to prevent overheating.
• Do not install in locations where flammable substances or gases
may be present (minimum distance 3 m).
• Do not install on wooden walls or other flammable supports.
• Install on a wall or strong structure suitable to bear the weight.
• Do not install in rooms where people live or where the prolonged
presence of people or animals is expected, because of the high
noise that the inverter produces during operation. The level of the
sound emission is heavily influenced by where the appliance is
installed (for example: the type of surface around the inverter,
the general properties of the room, etc.) and the quality of the
electricity supply.
• All installations over 6500’ (2,000 meters) must be assessed
by FIMER Technical Sales to determine the proper datasheet
derating.
• If the GROUNDING KIT is installed, the inverter must be installed
and operated in a restricted areas.
5.2.2 Tilting admittance
The unit can be installed with a maximum inclination as indicated
in the figures below.
Vertical
NO
OK
30° MAX
Horizontal
OK
30° MAX
Side
PVS-120
PVS-120
±1° MAX
ATTENTION –
A
In case of horizontal installation in outdoor
environment consider an installation with a minimum tilt of 3°
to avoid any water stagnation.
