Purpose of this guide

• This guide contains information regarding the installation and safe handling
of Suntech Power Co., Ltd photovoltaic module (hereafter referred to as “module”).
Suntech Power Co., Ltd referred to as “Suntech”.

• Installers must read and understand this guide prior to installation. For any
questions, please contact Suntech's Global Quality & Customer Support department or
our local representatives for more detailed information. Installers must follow all safety
precautions as described in this guide as well as local requirement and regulations by
law or authorised organisations.

• Before installing a solar photovoltaic system, installers should familiarize
themselves with its mechanical and electrical requirements. Keep this guide in a safe
place for future reference (care and maintenance) and in case of sale or disposal of the
modules.

• Suntech modules are tested and certified for installation worldwide. Different
regions may have dierent regulations for solar PV installations. In this guide, hereafter
"IEC Only" is used to refer to regions where IEC standard applies, e.g. Europe, Middle
East, most of Asia Pacific countries; " UL Only " is used to refer to regions where UL
standard applies, e.g. United States, Canada; all other references are global.

General safety

• Modules that fall under this application class may be used in system operation
at more than 50V DC or 240W, where general contact access is anticipated. Modules
qualied for safety under IEC 61730-2 and within this application class are considered
to meet the requirements for Safety Class II. (IEC Only)

• Installing solar photovoltaic systems requires specialized skills and knowledge.
Installation must only be performed by qualied personnel.

• Installers should assume all risks of injury that might occur during installation,
including, but not limited to, the risk of electric shock.

• One single module may generate more than 30V DC when exposed to direct
sunlight. Contact with a DC voltage of 30V or more is potentially hazardous.

• Do not disconnect under load.

• Photovoltaic solar modules convert light energy to direct current electrical energy.

They are designed for outdoor use. Modules can be ground mounted, mounted on
rooftops, vehicles or boats. The proper design of support structures lies within the
responsibility of the system designers and installers.

• When installing the system, abide to all local, regional and national statutory
regulations. Obtain a building permit if necessary.

• The electrical characteristics are within ±10 percent of the indicated values of
Isc, Voc and Pmax under standard test conditions (irradiance of 1000 W/m², AM 1.5
spectrum, and a cell temperature of 25°C (77°F) ).

• Only use equipment, connectors, wiring and support frames suitable for solar
electric systems.

Purpose of this guide

Handling safety

• Do not lift the module by grasping the module’s junction box or electrical leads.

• Do not sit, stand, step or walk on any side of the module.

• Do not drop the module or allow objects to fall on the module.

• Do not place any heavy objects on the module.

• Be cautious when placing the module down onto a surface, particularly when

placing it in a corner.

• Inappropriate transport and installation may break the module and void the
warranty.

• Do not attempt to disassemble the modules, and do not remove any attached
nameplates or components from the modules.

• Do not apply paint or adhesive to the module top surface or backsheet.

• To avoid damage to the backsheet, do not scratch, dent or hit the backsheet.

• Do not drill holes in the frame. This may compromise the frame strength, cause

corrosion of the frame and void the warranty.

• Do not scratch the anodized coating of the frame (except for grounding
connections at the grounding connection point on the back side of the module). It may
cause corrosion of the frame or compromise the frame strength.

• A panel with broken glass or torn backsheet cannot be repaired and must not be
used since contact with any panel surface or the frame can cause an electric shock.

• Work only under dry conditions, and use only dry tools. Do not handle panels
under wet conditions unless wearing appropriate protective equipment.

• When storing uninstalled panels outdoors for any period of time, always cover the
panels and ensure that the glass faces down on a soft at surface to prevent water from
collecting inside the panel and causing damage to exposed connectors.

Installation safety

• Never open electrical connections or unplug connectors while the circuit is under
load.

• Contact with electrically charged parts of the panels, such as terminals, can result
in burns, sparks and lethal shock whether or not the panel is connected.

• Do not touch the PV module unnecessarily during installation. The glass surface
and the frame may be hot; there is a risk of burns and electric shock.

• Do not work in the rain, snow or in windy conditions.

• Avoid exposing cables to direct sunlight in order to prevent insulation degradation.

• Use only insulated tools that are approved for working on electrical installations.

No.2 No.3

• Do not use mirrors or other magniers to concentrate sunlight onto the modules.

• Always use fall protection equipment when working from heights of 6 feet (183cm)

or above. Follow Occupational Safety and Health Act (OSHA) or local governing safety
regulations regarding Fall Protection. (UL Only)
