5. LIMITED WARRANTY
Please refer to Silfab General Terms and Conditions of
Sale for details of the modules’ limited warranty. Failure
to comply with this Safety and Installation Manual would
void Silfab Warranty for the PV modules as stated in the
General Terms and Conditions of Sale.
6. MODULE SPECIFICATION
Please refer to the appropriate datasheets for electrical
performance data and mechanical installation information.
7. SAFETY PRECAUTIONS
Installation should be performed only by authorized
personnel.
All installations must comply with the applicable geo-
graphic electrical standards. I.e. International, National,
Regional and local electrical standards etc.
Within the modules there are no user serviceable parts.
Do not attempt to repair any part of the modules. Do
not use or install broken modules
In order to reduce the risk of electric shock, prior to in-
stalling the modules, remove metallic jewelry and use
insulated tools during installation.
Modules produce voltage even when not connected to
an electrical circuit or load and have no on/o switch.
Modules can be rendered inoperative only by removing
them from sunlight, or by fully covering their front sur-
face with cloth, cardboard, or other completely opaque
non-marking material, or by working with them face
down on a smooth, at surface.
• Do not expose the modules to articially concentrated
sunlight.
• Do not stand on, drop, scratch, or allow objects to fall
on the modules.
• Do not lift the modules by the junction box or junction
box cables.
• Do not install or handle the modules when they are wet or
during periods of high winds. Modules in Silfab packaging
should not be kept outdoors for a period exceeding 60 days.
• Ensure that junction box cables are provided with strain re-
lief to avoid damage to the junction box, maintaining
a minimum bending radius of 50 mm at all locations
along the cable.
• Do not leave cable connectors exposed in adverse
climatic conditions. Water and dust deposits inside the
cable connectors can cause long term damage.
A module with broken glass, torn or cut backsheet, dam-
aged junction box, connectors or cables present electri-
cal safety hazards and must be removed from service.
The total voltage of modules connected in series cor-
responds to the sum of the voltages of the single mod-
ules; whereas connecting the modules in parallel re-
sults in adding up the currents. Consequently, strings
of inter-connected modules can produce high voltages
and high currents and constitute an increased risk of
electric shock and may cause injury or death.
For installation, maintenance, or before making any electrical
connection or disconnection, ensure all modules in the PV
array are exposed to a light intensity that is less than 400W/
m
2
as measured by an accurate solarmeter/ pyranometer.
Methods to reduce solar irradiance when making elec-
trical connections or disconnections include:
• Covering the modules with an opaque cloth or other
material in order to shield them from exposure.
• Making the connections during hours of low intensity of
solar irradiance (such as early morning or late afternoon).
8. INSTALLATION
8.1 Module Mounting Overview
The re rating of Silfab modules is valid only when
mounted in the manner specied in the mechanical
mounting instructions.
When installing Silfab modules, local building code
requirements and regulations must be adhered to at all
times. In case of roof mounting, the appropriate system
re class rating of PV module with Mounting system in
combination with roof covering and slope applications
should be considered. Silfab modules are re rating
Type 1 or Type 2 in accordance with UL 1703 standard.
For more information about the specic product, please
check DATASHEET or www.silfabsolar.com.
Sucient ventilation of the module backside is required
to maintain the Type 1 or 2 re rating, and therefore
the mounting conguration (e.g. sucient clearance)
should be adapted accordingly. The recommended
clearance distance is a minimum 10 cm (3 15/16”).
To maximize the rate of energy conversion, modules have to
be installed in the best orientation and tilt according to your
