Mechanical Installation; Planning And Design - Recom RCM 6MB Series Installation And Safety Instructions

WARNING:
• Use caution when cleaning the back surface of the module to avoid scratching the substrate materials.
• Precautions should be taken to avoid damage to the glass surface when unpacking, handling or storing the
modules since any damage to the glass surface may impact the power output of the modules.

3. MECHANICAL INSTALLATION

Planning and Design

• Before installation, check to ensure the sub-structure will accommodate expected system loads. This in-
cludes and is not limited to roof, foundations, mechanical structure and mechanical connections.
• All RECOM solar modules have a module fire resistance rating of Class Per UL 1703, the fire rating of this
module is valid only when mounted in the manner specified in the mechanical mounting instructions. The
system fire rating is determined by the module, rack and roofing materials. RECOM recommends not mixing
module fire performance type within a system.
• Mechanical structures should not contact the module back sheet, any racking or the microinverter under
any expected load conditions.
• Consider the following factors during system design, which will influence performance:
a. RECOM solar modules produce the most power when they are pointed directly at the sun, and should be
tilted for optimum system performance.
b. Proximity to obstructions have the potential to shade or damage the modules (examples below):
• walls
• buildings
• trees
• groundcover
• snow cover
• dust and debris
c. Designs should allow adequate airflow across the back of the module because elevated temperatures
will decrease energy yield.
d. Allow a minimum spacing of 10 mm between modules for thermal expansion.
