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. Sharp reserves the right to make changes to the product, specifi cations or installation manual without prior notice.
2. COMPONENTS
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 qualifi ed 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 is connected or
not.
4. PV modules produce electricity when the suffi cient 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.
< GENERAL SAFETY >
1. Consult local codes and other applicable laws concerning required permits on regulations concerning installation and inspection requirements.
2. Before installing a PV module, contact appropriate authorities to determine permit, installation and inspection requirements that should be followed.
3. Install PV modules and ground frames in accordance with applicable rules and regulations.
4. PV modules should be installed and maintained by qualifi ed personnel. Only installer / servicer personnel should have access to the PV module installation site.
5. No matter where the PV modules are installed, either roof mounted construction or any other type of structures above the ground, appropriate safety practices
should be followed and required safety equipment should be used in order to avoid possible safety hazards. Note that the installation of some PV modules on
roofs may require the addition of fi reproofi ng, depending on local building / fi re codes.
