User manual CONTAX KC130TM INSTALLATION

[. . . ] Since then, Kyocera has supplied millions of cells and modules throughout the world. With years of experience and state-of-the-art technology, Kyocera provides the highest quality PV power modules in a range of sizes designed to meet the requirements of the most demanding energy and power users worldwide. 5. SITE SELECTION In most applications, KC modules should be installed in a location where they will receive maximum sunlight throughout the year. In the Northern Hemisphere, the modules should typically face south, and in the Southern Hemisphere, the modules should typically face north. [. . . ] These are used to secure the modules to the supporting structure. An example of a ground mounted structure is shown in Figure 2. The four holes close to the corners of the module are most often used for attachment. Refer to the Mounting Specification Specifications for the position of these holes. Clearance between the module frame and the mounting surface may be required to prevent the junction box from touching the surface, and to circulate cooling air around the back of the module. If the modules are to be installed on the roof or wall of a building, the standoff method or the rack method is recommended. STAND-OFF METHOD: The modules are supported parallel to the surface of the building wall or roof. Clearance between the module frames and surface of the wall or roof is required to prevent wiring damage and to allow air to circulate behind the module. The recommended stand-off height is 4. 5 in. (about 115 mm) If other mounting means are employed, this may affect the Listing For Fire Class Ratings. RACK: The supporting frame is used to mount modules at correct tilt angles. The modules are not designed for integral mounting as part of a roof or wall. The mounting design may have an impact on the fire resistance. Figure 3. Standard Wiring Examples To wire Kyocera modules: A Determine the nominal system array voltage of your system. Each panel is equivalent to a 12 VDC nominal block. Standard array voltages 12, 24 and 48 volt are shown as examples in Figure 3. Open the "G" or "M" box cover by loosening the screws in the cover. The wire used to interconnect the solar modules may be single or two 2 2 conductors, from 14 AWG (2. 08 mm ) up to 10 AWG (5. 26 mm ) gauge stranded copper wire, in a "SUNLIGHT RESISTANT" jacket UF cable. This cable is suitable for applications where wiring is exposed to the direct rays of the sun. The maximum and minimum outer diameters of the cable that may be used with the cable connector are 8 mm and 6 mm respectively (Figure 4). Using a flat blade screwdriver, remove only the appropriate "KNOCK-OUTS" from the sides of the "G" or "M" box. Route wires through the knock-outs and clamps refer to installation example (see Figure 5). [. . . ] The racks must also be grounded unless they are mechanically connected by nuts and bolts to the grounded modules. The array frame shall be grounded in accordance with NEC Art 250.
