1.4 Limited warranty
Module warranty conditions are described in the LDK Solar document: LDK Solar Limited Warranty for
PV Module.
Ignoring the instructions and considerations described herewith can be a cause by LDK Solar to
invalidate the warranty in case of provable negligence. Please contact to the Technical Support
Service for any question s about warranties.

SAFETY
LDK Solar PV modules have passed all required safety tests and certification according to the IEC
61730 with Application Class A, and as Safety Class II according to the IEC 61140. Fire safety has
been rated as Class C, reaching all requirements to be mounted on Class A roofs.
2.1 General Safety
All PV modules should be installed according to all local and national
applicable standards, codes and regulations.
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.
Check and follow all safety precautions specified for other components of
the system.
Rooftop installations should be placed over fire resistant roofs only.
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 module top surface.
Do not use mirrors or other magnifiers to artificially concentrate sunlight on the modules. Do not
expose back sheet foils directly to sunlight.
2.2 Handling Safety
Do not stand or step on module.
Do not drop module or allow objects to fall on module.
To avoid glass breakage, do not place any heavy objects
on the module.
Do not set the module down hard on any surface.
Inappropriate transport and installation may break module.
2.3 Installation Safety
Installing solar photovoltaic systems requires specialized skills and knowledge.
One individual module may generate DC voltages greater than 30 volts when exposed to direct
sunlight. Contact with a DC voltage of 30V or more is potentially hazardous.
Do not disconnect under load.
It is recommended to completely cover the module with an opaque material during installation to
keep electricity from being generated.
Do not wear metallic rings, watchbands, ear, nose, lip rings or other metallic devices while installing
or troubleshooting photovoltaic systems.
Use only insulated tools that are approved for working on electrical installations. 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.
Do not attempt to repair any part of the PV module.

INSTALLATION
3.1 Design considerations
LDK Solar PV modules should be installed in a location where they will receive the maximum amount
of sunlight throughout the year. In the Northern Hemisphere modules should face south, while in the
Southern Hemisphere modules should face north. Therefore, modules facing more than 30 degrees
away from true South (or North) could lose approximately from 10% to 30% of their power output.
LDK Solar PV modules connected in series should be installed at same orientation and angle. Different
orientation or angles may cause a loss of power output due to the change in sunlight exposure.
To develop the final distribution of the modules conforming the photovoltaic system, consider to keep
suitable access to allow the maintenance and inspection works.
LDK Solar modules series must be installed in the following conditions:
Operating ambient temperature: -40°C to +85°C
Storage temperature: -40°C to + 60°C
Humidity: below 85RH%
When installing a module on a roof or building, ensure that it is securely fastened and cannot fall as a
result of wind or snow loads and provide adequate ventilation under a module for cooling
(recommended 10cm minimum air space between module and mounting surface).
LDK Solar modules are not allowed to be mounted in mobile applications or in marine environments
with direct contact with salty water, please avoid installing the modules on places directly exposed to
the sea.
