2.1.1 1 Explanation of safety guidelines Information on the Sharp Web-Site You can find the latest version of this installation manual and further information on SHARP’s web-site : www.sharp.eu This is the danger symbol. It is used in several versions in this manual to alert you to the potential risk of personal injury. 1.1 Warnings and notes in this manual Always use the latest version for your modules if you find a more recent release of the manual.
3.2.2 Dangerous, high DC voltages generated even at low levels of light, especially in a series connection. Mechanical safety precautions WARNING! Glass can crack, break or splinter. Beware of injury! Risk of fatal electric shock! • Never step or sit on PV modules. • Avoid knocking and bumping the surface, the edges and corners of the glass panels. • Never touch the electrical connections of a PV module under any circumstances, not even if you have disconnected the photovoltaic generator.
■ Individual PV modules: Electric arcs form when electrical connections are made or disconnected incorrectly. • Store individual PV modules in an upright position on wedges with suitable padding. Use adequate padding between the individual PV modules. • Avoid stacking individual PV modules, as well as the pallets they rest on. 4.1.
5.3 Improper mounting CAUTION! INWEIS • Do not attach the PV modules using nails. The vibration created in the process can cause micro fissures and loss of yield, and results in loss of warranty rights. • Do not attach the modules by welding. The temperatures created in the process can cause delamination, micro fissures and loss of yield, and results in loss of warranty rights Hot module parts in strong sunlight. Risk of burning! • Protect yourself from burning by wearing gloves and suitable clothing.
• Dry and cool operation can have a positive effect on the performance as well as the service life of a PV module. • Also for roof-integrated mounting, ensure good rear ventilation to minimise loss of output which results from a higher module temperature. Ensure adequate ridge ventilation, for example, with a roof ridge ventilator. 6.1.2 5.6 6.1.3 HINWEIS Original Multicontact® MC4-connectors: • Only plug original Multicontact® MC4 connectors into original MulticontactR®MC4 connectors.
6.2.1 6.4 Weather protection Lightning protection WARNING! HINWEIS • Lay the cables so that they exit the junction box from below. This prevents water, which runs along the cable, from collecting at the point where the cables exit the junction box. • For PV modules mounted horizontally, lay the cables in a U-form away from the junction box. • PV modules mounted vertically do not usually need any additional adjustments. Absence of or inadequate lightning protection.
Fig. 7 Impermissible clamp arrangements (2) d: Protruding clamps, e: Opposing clamps have different distances to the PV module corners, f: Asymmetrical clamps on the short sides. Fig. 3 Permissible alignment of mounting a : Parallel profiles for mounting; b: Parallel, aligned fingers of a mounting system. 7.2.2 7.1.2 Impermissible alignment Clamp dimensions Observe the following information for clamp lengths and depths. ■ Clamp lengths and depths Abb.
7.4 Insertion mounting The maximum permissible load is 2400Pa (for wind and snow) when mounting the modules by using crews, clamps or insertions systems Observe the manufacturer‘s instructions for the mounting system. Use the earthing holes for the potential equalisation. Although edge-to-edge mounting is possible (see also Ch. 5.4.1: „Intervals between PV modules with standard frames“), we recommend mounting at intervals. 7.
7.6.2 Tested snow load (The modules have passed the test in accordance with IEC61215.) Fig. 9b Mounting drawings for tested snow load All dimensions are shown in mm. ∆H is the clearance between bottom side of the module frame and surface mounting area. Permissible clamping area for the test shown as red crosses. 8 For the proper maintenance and repair of your solar photovoltaic system, contact installer.
• Salt (in coastal regions) Clean the components, if necessary. 8.1.2 8.2 Inspecting the documentation and drawings • Checking the PV module string plan 6, • Check the inverter's status reports • Determine and archive the annual output • Create and archive the inspection report. Review 8.4.1 CAUTION! Contact of live parts with water. Risk of electric shock! Carrying out a thorough review at least every 4 years is recommended.
after about 2 weeks of being exposed to weather conditions, as sunlight and rain break them down. 8.4.3 9 9.1 Insulating back sheet For operators: decommissioning Safety precautions Make sure you refer to the notes in Ch. 3.2.1: „Electrical safety precautions“. If you would like to continue using the PV module, also refer to Ch. 4.1: „Handling PV modules“ The insulating back sheet must not be cleaned. Nevertheless, if you still need to perform work behind the modules(e.g.
