3 safety precaution

3.1 The module is considered to be in compliance with UL 1703 only when the module is mounted in the manner specified by the mounting instructions below.

3.2 between PV 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 PV module. Spacing between PV modules must be a minimum of 1/8" (3.2 mm) to allow for thermal expansion. If the modules are to be installed on the roof or wall of a building, the stand-off method or the rack method is recommended.

3.3 The minimum spacing of 50mm (2”) is required between PV module and the mounting surface around the perimeter of PV module. Mounting hole size of each component is 9mm * 14mm. (Refer to Module Mounting Specifications). These are used for fixing PV modules to the supporting structure.

3.4 During transportation and installation, keeping children away from modules.

3.5 The modules are designed to fulfill the criteria of Application class A requirements according to IEC61730-1.Modules rated for use in application class A may be used in systems operating at greater than 50VDC or 240W, where general contact access is anticipated. Modules qualified for safety through IEC61730-1 and IEC61730-2 within application class A are considered to meet the requirements for safety class Ⅱ.In case of roof installation, PV module assembly shall be mounted on a fire resistant roof covering rated for the application. Modules are comprised of a glass front surface, polyethylene terephthalate (PET) back sheet with a Class C fire rating.

3.6 Modules shall be covered completely by non-transparent materials to prevent the current generated.

3.7 During transportation and installation, do not wear metal rings, bracelet, earrings, nose rings, lip rings or other metal accessories.

3.8 Employing equipments, connectors, wires and brackets which match solar power system. In a particular system, be sure to employ the same type of modules.

3.9 For a non-integral module or panel,the assembly is to be mounted over a fire resistant roof covering rated for the application.

3.10 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 .

3.11 In normal outdoor conditions, the generated current and voltage maybe different from the parameters listed in Table. Parameter table is measured under standard test conditions (STC), so concerning settling parameters of other parts of photovoltaic power generation system, such as rated voltage, the wire capacity, fuse, the controller capacity and module power output, it shall refer to the short-circuit current (Isc) and open circuit voltage (Voc) noted on modules’ label, with the redundancy value of 125% for design and installation.

3.12 Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and/or voltage than reported at standard test conditions. The values of ISC and VOC marked on this module should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, overcurrent device ratings, and size of controls connected to the PV output.

3.13 Do not touch terminals while a module is exposed to light. Provide suitable guards to prevent yourself contacting directly with 45 VDC or greater to avoid the hazard of electric shock or injury.
