Make sure flammable gases are NOT generated near the installation site.
According to Intertek-conducted IEC 61701, salt mist corrosion testing of photovoltaic (PV). The
module must not be soaked in the water or in the environment (i.e., fountain, spindrift, etc.) where the
module would touch water (pure water or brine) for a long term. If the modules are placed in an
environment of salt fog (i.e., marine environment) or sulfur (i.e., sulfur sources, volcanoes, etc.),
there is a risk of corrosion.
In locations that are 50m ~ 500mm from the ocean, stainless steel or aluminum materials must be
used to contact the PV modules, and the installation position must be processed with anti-corrosion
treatment; refer to the “Trina Solar Coastal Application White Paper”for detailed installation
requirements . Please contact with local technical support or contact us from

6. TILT ANGLE
The tilt angle measurement of the PV module refers to measuring the angle between the module and
the horizontal ground surface. For different projects there are different mounting angles. Trina Solar
recommends that the mounting tilt angle should be NOT less than 10°, or in accordance with local
regulations or follow the recommendations of experienced PV module installers.
The tilt angle of the PV module is measured between the PV module and a horizontal ground
surface.
In the Northern Hemisphere, the PV modules should typically face south, and in the Southern
Hemisphere, the PV modules should typically face north.
A clearance of at least 115mm (4.5in) (recommended) is provided between modules frame and the
surface of the wall or roof. If other mounting means are employed this may affect the UL Listing or
the fire class ratings.
7. INSTALLATION
7.1 INSTALLATION SAFETY
Always wear dry insulation protection equipment: insulated tools, head gear, insulated gloves, safety
belt and safety shoes (with rubber soles).
Do NOT wear metallic jewelry which can cause electric shock during installation.
Do NOT install modules under rain, snow or windy conditions.
Please keep the connector dry and clean during installation to avoid the risk of electric shock. It is
recommended to install it immediately after unpacking.
Due to the risk of electrical shock, do NOT perform any work if the terminals of PV module are wet.
Please install immediately after you unpacking.
Our module application class is class A, modules rated for use in this application class may be used
in systems operating at greater than 50V DC or 320W, where general contact access is anticipated;
Keep the PV module packed in the Trina carton until installation.
Please use an opaque material to completely cover the PV module surface during PV module
installation and wiring.
Do NOT unplug the connector if the system circuit is connected to a load.
Do NOT stand on the module glass while installing. There is a risk of injury or electric shock if glass
is broken.
Do NOT work alone (always work as a team of 2 or more people).
Do NOT damage the back sheet of PV modules when fastening the PV modules to a support with
bolts.
Do NOT damage the surrounding PV modules or mounting structure when replacing a PV module.
Cables shall be located and secured so that they will not be exposed to direct sunlight after
installation to prevent degradation of cables. Low drooping of cables from the terminal box must be
avoided. Low hanging cables could cause various problems such as animal biting, electricity
leakage in water, and fire.
