Page 5: Module Handling
MAXEON SOLAR TECHNOLOGIES, LTD. Safety and Installation Instructions ‐ Document 544753 Rev.B disclaims all warranties, express or implied, applicable to those modules should they be damaged in any way by such clamps. Therefore, the use of the above mentioned clamps by the Installer is at the Installer's sole risks. 5.2 Module Handling Do not place modules face forward in direct contact with abrasive surfaces like roofs, driveways, wooden pallets, railings, stucco walls, etc… The module front surface glass is sensitive to oils and abrasive surfaces, which may lead to scratches and irregular soiling. During storage, modules need to be protected from rain or any kinds of liquids. Required storage temperature is between 10°C to 40°C in a dry environment (humidity between 30 to 80%). Do not store modules outdoor to avoid moisture and wet conditions. Modules that feature antireflective coated glass are prone to visible finger print marks if touched on the front glass surface. Maxeon recommends handing modules with anti‐reflective glass with gloves (no leather gloves) or limiting touching of the front surface. Any finger print marks resulting from installation will naturally disappear over time or can be reduced by following the washing guidelines in Section 6.0 below. Any module coverage (colored plastic tarps or similar) during installation can lead to permanent front glass discoloration and is not recommended. The use of vacuum lifting pads can cause permanent marks on the front glass. Never lift or move the module using the cables or the junction box under any‐circumstances. System energization and shutdown procedures need to be followed based on respective National guidelines and local regulations. Safe site operational practices must be adhered before energizing the PV system (e.g. electrical continuity, avoiding direct contact with electrical/framing equipment, wearing safety PPE, etc.). System should be electrically disconnected during maintenance, upgrades, and modification works which can affect the operation of PV system. Systems should be disconnected in any cases of maintenance which can cause shading (e.g. chimney sweeping, any roof maintenance, antenna/dish installations, etc). ... - Page 6 MAXEON SOLAR TECHNOLOGIES, LTD.
