The modules mentioned in this installation manual are only allowed to be installed below
2000m above sea level.
Meaning of crossed-out wheeled dustbin: Do not dispose of electrical appliances as unsorted
municipal waste, use separate collection facilities. Contact your local government for
information regarding the collection systems available.
If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak
into the groundwater and get into the food chain, damaging your health and well-being. When
replacing old appliances with new ones, the retailer is legally obligated to take back your old
appliance for disposals at least free of charge.

PURPOSE OF THIS MANUAL
This manual applies exclusively to the solar photovoltaic module (here in after referred to
as Module) of TW solar energy Co., Ltd. (here in after referred to as TW). The contents
of this manual involve the installation methods, operation safety and maintenance
information of TW’s Modules.
Modules must be installed by professionals. Please read this manual carefully before
installation. The installers must follow all the rules in this manual strictly as well as local
requirements and regulations by law or authorized organizations.
Before installing, the installer must be familiar with their mechanical and electrical
requirements. Please keep this manual in a safe place for future reference (care and
maintenance) and in case of sale or disposal of the Modules.
DISCLAIMER

maintenance of the Modules which is not complying with the guidance of this manual,
including breakdown or damage of the Modules or any other expenses incurred.
Any customer shall not get any patent or authorization of the patent when using the
Modules, expressed or implied. Any infringement of patents or other rights of the third
party, which may result from the use of the Module, is not within the responsibility scope
of TW. The information in this manual is based on TW’s knowledge and experience and
is believed to be reliable, but such information including product specification (without
limitation) and relevant suggestions do not constitute a warranty, expressed or implied.

SAFETY & TRANSPORT
General Detailed Rules
Keep all the Modules and electrical connectors clean and dry before installation.
Use both hands to carry Modules. Do not overlap Modules.
Be cautious when carrying Modules. Slip-proof gloves are necessary.
Use supportive disassembling tools when unpacking.
The application level of TW module is Class A, which can be used in systems operating at
greater than 50 V DC or 240W, where general contact access is anticipated.
Do not stamp on Modules or put weight on Modules.
Do not disassemble or drop Modules. Do not remove any nameplate or component
of the module.
Do not use mirrors or magnifiers to concentrate sunlight onto Modules.
Do not lift the module by grasping the junction box or cable wire.
Do not use any sharp object with Modules.
Do not directly apply pressure on the glass surface or backsheet of Modules.
Do not touch the surface of the coated glass with bare hands.
Ensure all contacts and the operating environment are clean and dry.
Module Carry and Installation Instruction

SAFETY & TRANSPORT
Electrical Performance Safety
PV modules can produce DC current under sunlight. Any contact of exposed metal at
module's wiring parts may result in electrical shock or burn. Any contact of 30V or larger
DC Voltage can be fatal.
In case of no connected load or external circuits, modules can still produce voltage.
Please use insulation tools and wear rubber gloves when operating modules in the
sunlight.
No switch is on the PV modules. Operating of PV modules can only be stopped when
they are kept from sunlight or covered by hard board or UV-proof materials or when the
angle of the modules facing sun are placed on smooth and flat surfaces.
To avoid electric arc or electric shock hazards, please do not break down electric
connection in loaded conditions. Incorrect connections will also lead to electric arc or
shock. Keep connectors dry and clean and make sure that they are in good operating
condition. Do not insert other metals into the connectors or carry out electric connection
by whatever means.
Snow, water or other reflective medium in surrounding environments that intensify light
re-flection will increase output current and power. And module voltage and power will
increase under low temperature condition.
If module glass or other sealing materials are damaged, please wear personal protective
equipment and then isolate modules from the circuit.
Work only under dry conditions，and use only dry tools. Do not operate when modules
are wet unless you wear personal protective equipment. Please follow the cleaning
requirements in this manual when cleaning modules.
Installation must be carried out under the guidance of a qualified electrician.
No matter how weather condition is, personnel entering the power station shall wear
safety helmet, insulating gloves and insulating shoes correctly, taking-safety protection
measures.

Description of Package Signs
Before the operation, it is necessary to read carefully the unpacking instruction and outer
packing box instruction, and carry out the operation as instructed.
1. DO NOT expose the module to rain or
moisture.
2. The Modules in the carton box are fragile.
Handle with care.
3. The package shall never be upside down
during the transportation.
4. It is prohibited to tramp on the packing
box and module.
5. During the stacking of the Modules, the
outer packing box can be stacked not
exceed the maximum layer allowed .(n=2
means it is allowed to stack for at most
two layers.)
6. One module shall be handled by two
people together.

SAFETY & TRANSPORT
Unloading, Transportation and Storage
When the Modules are delivered to the project site, the freight car shall be ready in the
flat, even and open area for parking and unloading.
Forklift unloading: Choose the appropriate carrying forklift according to the commodity
weight, unload the Modules from the freight car and place them on flat ground.
Unloading with a crane: Affix the lifting belt in the wood supporting frame buckle (Fig. 1,
2). It is allowed only to lift one pallet at a time. Before lifting, it is necessary to confirm
whether the pallet and paper box are damaged and ensure that the lifting rope is robust
and firm. When being lifted close to the ground, the paper box will be gently placed in a
relatively flat position on the project site by two people, one on each side.

It is prohibited to stack the Modules in the project site.
During the transportation at the project site, the Modules shall not be stacked, but only
allowing for one layer in transportation.

SAFETY & TRANSPORT
Storage in the project site warehouse:
Storage environment requirements: Humidity＜85%, temperature -20 ~+50℃; Modules
statically stacked for ≤2 layers.
Temporary storage at the project site: The Modules shall be stored in a dry,
well-ventilated place. They shall not be stacked but shall be covered with waterproof
cloth to prevent dampness in the Modules.
Unpacking description
1. In the outdoor unpacking process, it is prohibited to operate in rainy conditions;
2. If there is wind in the field, special attention shall be paid. Particularly in the event of
heavy wind, it is recommended not to handle the module, and it is necessary to properly
secure the unpacked Modules;
3. The working surface shall be such that the packing box can be placed in a stable, level
position, avoiding being overturned;
4. During the unpacking, it is necessary to wear protective gloves, and avoid scratching
the hands and leaving the fingerprints on the glass;
5. In the case of operation not according to the requirements or in the case of an
unskillful operation, it will result in the fall-off of the protective corner in small amounts,
which will be normal. The effect of the protective corner is to reduce damage due to external
force during transport, and the fall-off of the protective corner will not influence the reliability
of the Modules;
6. Before the unpacking, it is necessary to carefully check the product information on the
carton box, and carefully read the unpacking instruction;
7. Every module shall be carried by two people. When carrying the module by two
people, it is prohibited to pull the junction box.
