Safety The instructions related to safety and use indicated in the this installation manual are intended for the prevention of unexpected danger, damage, or failure. Non-compliance with the instructions may cause product damage, product failure, and/or serious bodily injury or death. Do not contact electrically active parts of the panel, such as terminals, without appropriate safety gear. Contact may result in lethal spark or electric shock. Do not use or install if the module is broken or torn.
Before & After Installation Before Installation Please carefully read this manual before installation. • Contact with electrically active parts of the panels, such as terminals, may result in burns, sparks and lethal shock whether the panel is connected or disconnected. • Panels produce voltage even when not connected to an electrical circuit or load. • Solar module installation and maintenance must be performed by qualified and authorized installer.
Electrical Installation • The junction box should not be opened. Opening the junction box will void the warranty. • Panels with a suspected electrical problem should be returned to LG Electronics for inspection and possible repair or replacement as per the warranty conditions provided by LG Electronics Electrical Connections • Shock hazard may occur near the solar modules electrical connections.
Electrical Installation General Wiring • LG Electronics recommends that all wiring be double insulated with a minimum rating of 90°C (194°F). • All wiring should use a flexible copper (Cu) conductor. • The minimum size should be determined by the applicable codes. • LG Electronics recommends a size no smaller than 12AWG. Module frame Bolt Flat washer Star washer Cup washer Grounding wire Earth Grounding • All work must be conducted in conformance with all Federal, State, and local codes and standards.
Mechanical Installation Mounting Methods General Information • Select the appropriate orientation to maximize sunlight exposure. • Module should not be mounted or stored in a way that the front/top glass faces downward in order to prevent water from entering the junction box, which could cause a safety hazard. • Clearance between the solar module frames and structures such as roofs or ground is required to prevent wiring damage and to allow air to circulate behind the solar module.
Mechanical Installation Mounting Type LGXXXN1C(W)-B3 Clamping Type (Long Side) Use four mounting holes on two opposite sides. Clamping Range (230mm) 270mm 270mm Use four clamps on the long frame. Clamping Type (Short Side) This method is not tested by IEC/UL.
