、General Information
This guide contains information regarding the installation and safe handling of the photovoltaic module
(hereafter is referred to as “module”) produced by hina Sunergy (Nanjing) o., Ltd (hereafter is referred to
as “ SUN”.)
Installers must read and understand the guide before installation. Any questions, please contact our
customer service department for further explanations. The installer should conform to all safety precautions in
the guide and local codes when installing a module. Failure to follow these instructions may result in death,
bodily injury or damage to property.
Before installing a solar photovoltaic system, installers should become familiar with the mechanical and

◆ When installing the system, abide with all local, regional and national statutory regulations. Obtain a
building permit where necessary.
◆ Installing solar photovoltaic systems may require specialized skills and knowledge. Installation should be
performed only by qualified persons. Installers should assume the risk of all injury that might occur during
installation, including, without limitation, the risk of electric shock.
◆ Abide with the safety regulations for all other components used in the system, including wiring and cables,
connectors, charging regulators, inverters, storage batteries and rechargeable batteries, etc. Use only
equipment, connectors, wiring and support frames suitable for a solar electric system. Always use the
same type of module within a particular photovoltaic system.
◆ Photovoltaic modules are designed for outdoor use. Modules may be mounted on ground, rooftops,
vehicles or boats. Proper design of support structures is responsibility of the system designers and
installers. Use of mounting holes is suggested in a following paragraph.
◆ Do not install or handle the modules when they are wet or during periods of high wind. Keep the junction
box cover closed at all times.
◆ Do not use or install broken modules. If the glass is broken, or the back sheet is torn, contact with any
modules surface or the frame can cause electric shock.

current.

◆
◆ Under normal outdoor conditions the module will produce current and voltages that are different than
those listed in the date sheet. Data sheet values are values expected at standard test conditions.
Accordingly, during system design, values of short-circuit current and open-circuit voltage should be
multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacity, fuse
ratings and size of controls connected to the modules or system output.

、Produ t Identifi ation
Each module has five labels providing the following information:
◆ Nameplate：describes the product type, rated power, rated current, rated voltage, open circuit voltage,
short circuit current, all are measured at ST ; weight, dimension, maximum system voltage, the fuse
rating and power tolerance are all shown on the nameplate. Generally，power tolerance is ±3%。
◆ Barcode：each module has a unique serial number. The serial number has 16 digits. The “ SUN” is the
short name for hina Sunergy (Nanjing) o., Ltd. The 5th digit refers to the cell manufacturer, AB used
to represent. And the 6th digit refers to the modules manufacturer address, AB used to represent. The 7th
digit refers to the modules production month. AB used to represent. For example, “A” refers to
“January”； “L” refers to “December”；The 8th digit refers to the modules production workshop. “1”

◆ Always observe the instructions and safety precautions included with the support frames to be used with
the modules. Do not attempt to drill holes in the glass surface or additional mounting holes in the frame.
To do so will void the warranty.

◆ When installing module on a roof, ensure that the roof construction is suitable. In addition, any roof
penetration required to mounting the module must be properly sealed to prevent leaks. In some cases, a
special support frame may be necessary.
◆ The roof installation of solar modules may affect the fireproofing of the house construction. The modules
Fire Resistance rated lass is lass , and are suitable for mounting over a class A roof. Do not install
modules on a roof or building during strong winds in case of accidents.

conductor or strap may be copper, copper alloy, or other material acceptable for use as an electrical
conductor per respective National Electrical odes. The grounding conductor must then make a
connection to earth using a suitable earth ground electrode.
◆ Attach a separate conductor as grounding wire to one of the 6mm diameter grounding holes marked with
the grounding symbol on the module frame with a set of M4 or M5 screw, cup washer, flat washer, tooth
washer, and M4 or M5 nut. This is to ensure positive electrical contact with the frame.
