User manual CONTAX KC-TYPE INSTALLATION

[. . . ] These cells cover nearly 100% of the module's surface. To protect the cells from the most severeenvironmental conditions, they are encapsulated between a tempered glass cover and an EVA pottant with PVF back sheet. The entire laminate is installed in an anodized aluminum frame for structural strength and ease of installation. APPLICATIONS Kyocera modules are a reliable, virtually maintenance free power supply, designed to operate efficiently in sunlight. [. . . ] The maximum and minimum diameter of the cable that may be used with the cable connector are 8 mm and 6 mm respectively. Using a flat blade screwdriver, remove only the appropriate "KNOCK-OUTS" from the sides of the "G" or "M" box. Read the enclosed instructions for routing wires through the knock-outs and clamps. Remove approximately ½" of insulation on the ends of the wires and insert them under the appropriate "POSITIVE" or "NEGATIVE" terminal screws in the junction box. The wires should be installed with some slack; excess wire should be cut off. (Figure 7 and 8) Install cable with appropriate hardware in accordance with NEC Article 250 or national and international rules. Do not overtighten, as the terminal can be damaged. The output wiring from the final module is generally run to a separate array junction box. In commercial system, this wiring from the array box to the next component (i. e. or charge regulator, etc. ) is generally run in conduit. The maximum electrical rating of an acceptable series fuse is 4 ~ 12 amperes. 9. BLOCKING DIODES Blocking diodes can prevent nighttime battery discharging caused and prevent modules from loss of array output and being damaged or destroyed by reverse current flow. KYOCERA modules do not contain a blocking diode when shipped from the factory, however most battery charging regulators do have this feature. BYPASS DIODES Partial shading of an individual module in a 12 volt or higher "series" string (i. e. two or more modules) can cause a reverse voltage across the shaded module. Current is then forced through the shaded area by the other modules in series. By having a bypass diode, the forced current will bypass the shaded module in a series circuit, thereby minimizing module heating and array current losses. For 12-volt systems and higher: Each solar module junction box has a diagram illustrating the proper direction for the by- pass diode to be installed between two of the terminal screws (Figure 11, Figure 12). When the solar modules are connected as individual series strings first, and then these strings are connected in parallel, bypass diodes should be used in each junction box. This is the simplest wiring arrangement for most installations. At a minimum the bypass diodes must have the following electrical characteristics: · Rated Average Forward Current [I)$Y] Above maximum system current at highest operating temperature. · Rated Repetitive Peak Reverse Voltage [V772] Above maximum system voltage at lowest operating temperature. H. [. . . ] BATTERY · When solar modules are used to charge batteries, the battery must be installed in a manner which will protect the performance of the system and the safety of its users. The battery should be away from the main flow of people and animal traffic. Select a battery site that is protected from sunlight, rain, snow, debris, and is well ventilated. Most batteries generate hydrogen gas when charging, which is explosive. [. . . ]
