1. INTRODUCTION
This Installation Manual contains essential information for the electrical and mechanical installation that you must know before installing SHARP PV modules. This also contains safety information you need to be familiar with. All the information described in this manual are the intellectual property of SHARP and based on the technologies and experiences that have been acquired and accumulated in the long history of SHARP. This document does not constitute a guaranty, expressed or implied. SHARP does not assume responsibility and expressly disclaims liability for loss, damage, or expense arising out of or in any way connected with installation, operation, use or maintenance of the PV modules. No responsibility is assumed by SHARP for any infringement of patents or other rights of third parties that may result from use of PV module.

10. When replacement parts are required, be sure the installer/servicer uses parts specified by the manufacturer with same characteristics as the original parts. Unauthorized substitutions may result in fire, electric shock, or other hazard.
11. Consult your local building and safety department for required permits and applicable regulations.
12. In regions with snow, the module can sustain a snow load of up to 50cm (when the module is mounted in the portrait orientation / short frame side facing down) or 100cm (when the module is mounted in the landscape orientation / long frame side facing down).
13. As a result of sliding snow, the mechanical load increases when the number of module rows in the matrix of a PV installation increases. When mounting the module in the portrait orientation for more than 3 rows, the accumulated snow load may cause the lower edge of the module frame to deform. Take necessary measures (e.g. snow stopper) to avoid possible damage.
14. Periodically remove any overhanging snow and/or ice from the module framework as it may cause deformation of the module frame.
To reduce the risk of electric shock, do not touch.
3. GENERAL INFORMATION
(INCLUDING WARNING AND SAFETY)
The installation of PV modules requires a great degree of skill and should only be performed by a qualified licensed professional, including licensed contractors and licensed electricians. Please be aware that there is a serious risk of various types of injury occurring during the installation including the risk of electric shock. All SHARP PV modules are equipped with a permanently attached junction box that will accept variety of wiring applications or with a special cable assembly for ease of installation, and they do not require special assembly.

GENERAL WARNING
1. PV modules are heavy. Handle with care.
2. Before you attempt to install, wire, operate and maintain the PV module, please make sure that you completely understand the information described in this installation manual.
3. Contact with electrically active parts of a PV module such as terminals can result in burns, sparks and lethal shock whether the PV modules are connected or not.
4. PV modules produce electricity when the sufficient sunlight or other sources illuminate the module surface. When the modules are connected in series, voltage is cumulative. When the modules are connected in parallel, current is cumulative. As a result, a large-scale PV system can produce high voltage and current which could present an increased hazard and may cause serious injury or death.
5. Do not connect the PV modules directly to the loads such as motor since the variation of the output power depending on the solar irradiation causes damage for the connected motor. 1: In the case of a brushless motor, the lock function
becomes active and the hall IC is most likely to be damaged.
2: In the case of a brush type motor, the coil is most likely
to be damaged.
6. In case of snow build-up, snow would slide easier on the smooth surface of the module than other parts of the roof. Snow may suddenly slide, fall off the roof and hit nearby objects/areas. Take preventive measures (e.g. snow stopper) when there is possible risk such case would cause an injury or a damage.

the PV module while exposed to sunlight. Place a
defective PV module in a carton so PV cells are completely shaded.
19. In case of series connection, the maximum open circuit voltage must not be greater than the specified maximum system voltage. The voltage is proportional to the number of series. In case of parallel connection, please be sure to take proper measure (e.g. fuse for protection of module and cable from over current, and/or blocking diode for prevention of unbalanced strings voltage) to block the reverse current flow. The current may easily flow in a reverse direction.
20. Keep modules away from children.
HANDLING SAFETY
1. Do not cause an excessive load on the surface of PV module or twist the frame. The glass surface can easily break.
2. Do not stand or step on the PV module. The surface glass of PV module is slippery.
3. Do not hit or put excessive load on the glass or back sheet. The PV cell is very thin and can be easily broken.
4. Do not scratch or hit at the back sheet. The back sheet is vulnerable.
5. Do not damage the junction box or do not pull the cables. The junction box can crack and break.
6. Never touch junction box or the end of output cables with bare hands when the PV module is irradiated. Cover the surface of PV module with cloth or other suitable sufficiently opaque material to isolate the PV module from incident light and wear rubber gloves when handling the wires to avoid electric shock.
7. Do not scratch the output cable or bend it with force. The insulation of output cable can break and may result in electricity leakage or shock.
8. Do not pull the output cable excessively. The output cable may unplug and cause electricity leakage or shock.
9. Do not drill holes in the frame. It may compromise the frame strength and cause corrosion.
10. Do not scratch the insulation coating of the frame (except for grounding connection). It may cause corrosion of the frame or compromise the framework strength.
11. Do not touch the PV module with bare hands. The frame of PV module has sharp edges and may cause injury.
12. Do not drop PV module or allow objects to fall down on the PV module.
13. Do not concentrate sunlight artificially on the PV module.
14. Do not hold the PV module on one side. The frame may bend or twist. Hold the PV module at opposite sides.
15. Do not touch the anti-reflective coated glass since finger prints and/or stains can be easily left on the glass surface.
INSTALLATION SAFETY
1. Always wear protective head gear, insulating gloves and safety shoes (with rubber soles). Do not wear metallic jewellery to prevent electric shock during installation.
2. Keep the PV module packed in the carton until installation.
3. Do not touch the PV module unnecessarily during installation. The glass surface and the frames get hot. There is a risk of burn, or electric shock.
4. Do not work under rain, snow or windy conditions.
5. Use dry insulated tools.
6. Do not drop tools or hard objects on PV modules
7. When working at heights, wear a safety belt and take care not to drop any items (e.g., PV module or tools).
8. Make sure flammable gases are not generated near the installation site.
9. Completely cover the PV module surface with an opaque material during PV module installation and wiring.
10. Plug in the connector tight and ensure the wiring work. Make sure that the connectors have been locked by a snap-in latch. Any treatments over the connectors which may allow to unlock the snap-in latch shall not be done.
11. Due to the risk of electrical shock, do not perform any work if the terminals of PV module are wet.
12. Do not touch the junction box and the end of output cables, the cable ends (connectors) , with bare hands during installation or under sunlight, regardless of whether the PV module is connected to or disconnected from the system.
13. Do not unplug the connector if the system circuit is connected to a load.
14. Do not stomp on the glass at work. There is a risk of injury or electric shock if glass is broken.
15. Do not work alone (always work as a team of 2 or more
