User manual CONTAX KC130TM INSTALLATION

[. . . ] 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. Modules facing 30 degrees away from true South (or North) will lose approximately 10 to 15 per cent of their power output.

(15 mm) is required between the solar module and the mounting surface around the perimeter of the solar module. The frame of each module has 0. 28" diameter (7 mm) mounting holes (Refer to Module Mounting Specifications). 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. (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. 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). Gently hand tighten the terminal screws with cross tip (Phillips head) screwdriver. [. . . ] GROUNDING We recommend you attach all module frames to an earth ground. Attach a separate ground wire to one of the holes marked `ground' on the module frame with a screw and bonding or external tooth washer. 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. KYOCERA Solar Inc.
