User manual CONTAX KD185GX-LPU 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-LPU series modules are comprised of a glass front surface, polyethylene terephthalate (PET) backsheet with a Class C fire rating. 2. APPLICATIONS KDxxxGX-LPU series modules are a reliable, virtually maintenance-free direct current (DC) power source, designed to operate at the highest level of efficiency. [. . . ] KDxxxGX-LPU series modules may be attached to a support structure by the following methods. When installing modules in snowy area, an appropriate countermeasure has to be taken to prevent possible damages to the lower side frame by slipping snow (e. g. attach supporting parts to the lowest modules. ). Any damage caused by snow or such countermeasure is not covered under warranty. BOLTING: Utilizing 5/16" or 8 mm steel hardware structure through the existing . 35" (9 mm) diameter mounting holes in the module frame and then through KDxxxGX-LPU series module mounting holes on the support structure. Tighten the screws with adequate torque (usually 132 in-lb). Support structure should have enough strength to keep the mounting span. Refer to the Module Drawings for the position of PV module mounting holes. output connections are marked "Do not disconnect under load". KDxxxGX-LPU series modules and most PV system components have a maximum system voltage rating of 600 volts DC. Some grid feed in systems operate at or near this voltage rating. Like other polycrystalline the PV modules, the open circuit voltage of the KDxxxGX-LPU series modules increases as the ambient temperature decreases. Maximum system voltage is computed as the sum of the open-circuit voltage of the series-connected PV modules for the lowest expected ambient temperature. Refer to the National Electrical Code Article 690-7(a) for determining the maximum number of KDxxxGX-LPU series modules that can be placed in series. Temperature coefficients, specific to the module of use, can be used to provide the most accurate prediction of module voltage under temperature extremes. NOTE: Install the maximum number of series connection for the KDxxxGX-LPU series 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-LPU series 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-LPU series 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.

MAINTENANCE KDxxxGX-LPU series modules are designed for long life and require very little maintenance. Under most weather conditions, normal rainfall is sufficient to keep the module glass surface clean. [. . . ]
