• Securely ground the PV module frame and the mounting framework following local regulations.
• Install a residual current device (RCD) as prescribed by local regulations.
• DO NOT expose the backside of the module to sunlight.
• DO NOT install the modules in places where they can be shaded by objects such as buildings or trees.

2-3-2. Mounting using the "Clipping method"
"The clipping method" is a way to secure modules on steady base profiles (rail structures. etc.,) with "clipping" materials to hold the top of the frame, without directly securing it with bolts and nuts on the back of the module. Mitsubishi Electric Corp. doesn't specify or warrant any materials, e.g. base profile and clipping materials etc., related to the clipping method.
• The base profile should be perpendicular to the longer side
of the module (see figure below).
• The
•
Refer to the figure for the proper attachment.
• Secure the clips using M6 (1/4”) or larger (M8 (5/16”)) bolts
for where heavy snow loads are expected.
• Make to use clips that reach at least 5mm in from the edge
of the module frame.
• Use clipping material with sufficient strength and proper
form that can withstand forces from wind pressure and snowfall pressure specific to the local climate.
• Secure bolts with the appropriate torque to avoid
deformation of the module frame.
• Take precaution in utilizing locking fasteners to avoid
loosening of the panel from its original anchored position.
• Note that the drainage holes at each corner of module
should not be blocked by the base profile.

2-3. MOUNTING
• Use mounting framework that can withstand forces from wind
pressure and snowfall pressure specific to your local climate.
• Use mounting framework and brackets that can withstand the environment where the PV modules are to be used. Select
proper corrosion resistant materials and coatings.
• Use appropriate safeguards and components to install the
modules.
• PV modules shall be mounted over a fire resistant roof
covering rated for the application and on any slope less than
5in/ft (127mm/305mm) to maintain a fire Class rating.
• Installing the modules at an angle less than 2°can result in
decreased module output due to dirt and dust accumulating on the module surface.
• Make sure there is enough space for air circulation behind
the PV modules to dissipate heat.
• DO NOT open any additional holes in the modules.
• The module is Type 2 of Fire Performance.
2-3-1. Mounting using bolt holes
Mounting examples:
• Fasten the corner holes of the PV module with M8 (5/16”)
stainless steel bolts to the mounting framework with a
torque of 4.5 to 6N·m (3.3 to 4.4 ft-lb).
•
Use spring washers and flat washers to fasten the PV module as
shown in figure1.
• Install the PV module securely
by fastening the appropriate bolts with double nuts and locking washers.
• Make sure that there is more than a 5 mm gap between
modules to prevent buckling caused by thermal expansion.
CAUTION
WARNING
2.INSTALLATION
Refer to Local Code (US: National Electrical Code) standards,
construction rules and safety instructions regarding installation of the PV modules. Electrical installations in Canada shall be in accordance with
CSA. C22. 1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part1.
2-1. CLIMATE CONDITIONS
Install the PV module within the following conditions:
•
Ambient monthly mean temperature: -20°C to 40°C (-4 to 104 °F)
• Operating temperature: -30°C to 83°C (-22 to 181 °F)
• Allowable pressure: up to +2400/-3000Pa
• Water resistance/damage: The PV modules shall not be
immersed in water and shall not be continually exposed to a source of water, such as a sprinkler, fountain, etc.
• Corrosion warning: The PV modules shall not be installed in
corrosive areas such as:
-- Salty areas: areas where salty water such as ocean
spray comes in direct contact with the module, or
-- Sulfurous areas: areas near sulfurous volcanos and
sulfurous springs.
Note
In case of installation in Asian countries, PV modules shall not be installed in corrosive areas within 500m from a body of salt water and/or areas where there is direct contact with
salty wind.
2-2. ORIENTATION
• Install the PV modules facing South in the Northern Hemisphere or North in the Southern Hemisphere.
• PV modules connected in series should be installed in the same orientation and angle. Different orientation or angles
may cause loss of output power due to the different amount of sunlight being absorbed by the modules.
• Do not allow the modules to be shaded at anytime. Shade causes loss of electrical output, even though the
factory fitted bypass diode will reduce such loss to some extent.
1-2. MULTIPLYING FACTOR
Under normal conditions, the PV module is likely to experience conditions that produce more current and/or voltage than reported under Standard Test Conditions. Accordingly, the values of Isc and Voc marked on this module should be multiplied by a factor of
1.25 when determining component voltage ratings, conductor capacities (cross sectional area), fuse sizes, and size of controls connected to the PV output. Customers in US should refer to article 690.8 the National Electrical Code for an additional multiplying factor of 125 percent (80 percent derating), which may be applicable. Customers in other locations should refer to the codes relevant to
the location of installation for further guidance. Voc should be increased by a factor based on the lowest ambient temperature
recorded for the location. To determine the corrected value for Maximum System Voltage follow the guidelines in article 690.7 of the NEC or applicable section in the CEC. The voltage temperature coefficient for the module in use should be used when determining Maximum System Voltage.

• Securely ground the PV modules and the mounting
framework.
