User manual CONTAX KD225GX-LPB INSTALLATION

[. . . ] Do not expose the back of the module to direct sunlight In Canada installation shall be in accordance with CSA C22. 1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1. FIRE RATING In case of roof installation, PV module assembly shall be mounted on a fire resistant roof covering rated for the application. KDxxxGX-LPB modules are comprised of a glass front surface, polyethylene terephthalate (PET) backsheet with a Class C fire rating. GROUNDING Refer to "Grounding" section. 2. APPLICATIONS KDxxxGX-LPB modules are a reliable, virtually maintenance-free direct current (DC) power source, designed to operate at the highest level of efficiency. [. . . ] Support structure should have enough strength to keep the mounting span. Refer to the Module Drawings for the position of PV module mounting holes. NOTE: Install the maximum number of series connection for the KDxxxGX-LPB modules so that the system voltage is less than 600 V. NOTE: Do not connect the modules in parallel without maximum over current protection. NOTE: The minimum diameter that the cable can be bent for the KDxxxGX-LPB modules is 1. 93" (49mm). NOTE: In normal conditions, PV modules may produce larger current and/or voltage than reported in the standard test conditions. Therefore, when voltage evaluations for components, capacity of conductors, size of fuses, and size of control systems connected to the module output are determined, multiply the values of short- circuit current (Isc) and open-circuit voltage (Voc) that are marked in KDxxxGX-LPB modules by the coefficient, 1. 25. 8. GROUNDING Before installation, contact the local code authorities to determine the necessary grounding requirements. When installing in US market, attach all PV module frames to an earth ground in accordance with the National Electrical Code (NEC) Article 250. Proper grounding is achieved by connecting PV module frames and all metallic structural members contiguously to one another using a suitable grounding conductor. The grounding conductor shall be of copper, copper alloy or another material suitable for use as an electrical conductor per NEC. The grounding conductor must then make a connection to earth using a suitable earth grounding electrode. Ensure positive electrical contact through the anodizing on the module frame extrusion by utilizing one of the following methods. Attach the grounding conductor: (1)to one of the . 35" (9mm) diameter holes marked "ground" using 5/16" stainless steel hardware. Tighten the screws with adequate torque (usually 132 in-lb). Avoid direct contact of copper ground conductor to aluminum frame. (2)to a ground lug (manufacturer:ILSCO, model:GBL-4DBT). Tighten the screws with adequate torque (usually 62 in-lb). Use #10-32 stainless steel hardware to attach the lug to the module frame by the torque of 40 in-lb. A stainless steel star washer, positioned between the lug and the anodized surface of the frame, must be employed to break through the anodized layer of the frame extrusion and electrically connect the ground lug to the conducting aluminum frame material. As a general rule, avoid direct contact of copper or copper alloyed ground conductors with the aluminum module frame. All ground bond securing hardware in contact with either the aluminum module frame and/ or copper or copper alloy ground conductors must be stainless steel.
