1. General Information
1.1 Overview
Thanks for choosing Jinko Solar PV modules. In order to ensure the PV modules are installed correctly,
please read the following installation instructions carefully before modules are installed and used.
Please remember that these products generate electricity and certain safety measures need to be taken
to avoid danger.
Make sure the module array is designed in such a way not to exceed the maximum system voltage of
any system component such as connectors or inverters.
The assembly is to be mounted over a fire resistant roof covering rated for the application. Before
mounting the module, please consult your local building department to determine approved roofing
materials.
The modules are qualified for application class A: Hazardous voltage (IEC 61730: higher than 50V DC;
EN 61730: higher than 120V), hazardous power applications (higher than 240W) where general contact
access is anticipated. Modules qualified for safety through EN IEC 61730 -1 and - 2 within this application
class are considered to meet the requirements for Safety Class II.
1.2 Warnings
PV modules generate DC electrical energy when exposed to sunlight or other light sources. Active
parts of module such as terminals can result in burns, sparks, and lethal shock.
Artificially concentrated sunlight shall not be directed on
the module or panel.
Front protective glass is utilized on the module. Broken
solar module glass is an electrical safety hazard (may
cause electric shock or fire). These modules cannot be
repaired and should be replaced immediately.
To reduce the risk of electrical shocks or burns, modules
may be covered with an opaque material during installation to avoid injury.
The installation work of the PV array can only be done under the protection of sun-sheltering covers
or sunshades and only qualified person can install or perform maintenance work on this module.
Follow the battery manufacture’s recommendations if batteries are used with modules.
Do not use this module to replace or partly replace roofs and walls of living buildings.
Do not install modules where flammable gas may be present.
Do not remove any part installed by Jinko Solar or disassemble the module.

All instructions should be read and understood before attempting to install, wire, operate and
maintain the module.
Don’t lift up PV modules using the attached cables or the junction box.
Do not touch live terminals with bare hands. Use insulated tools for electrical connections.
All PV systems must be grounded to earth. If thereis no special regulation, please follow the National
Electrical Code or other national code.
Under normal conditions, a photovoltaic module is likely to experience conditions that produce more
current and/or voltage than reported at standard test conditions. Accordingly, the value of Isc and
Voc marked on the module should be multiplied by 1.25 when determining PV system component
voltage ratings, conductor current ratings, fusesizes, and size of controls connected tothePV output.
Once the PV module has been shipped to the installation site, all of the parts should be unpacked
properly with care.
Do not stand or step on the PV module like below pictures show. This is prohibited and there is a
risk of damage to the module and cause injury for you.
Only PV modules with the same cell size should be connected in series.
During transporting modules, please attempt to minimize shock or vibration to the module, as this
may damage the module or lead to cell micro cracks.
During all transportation situations, never drop the module from a vehicle, house or hands. This will
damage module.
Do not clean the glass with chemicals. Only use tap water. Make sure the module surface
temperature is cool to the touch. Cleaning modules with cool water when module surface temp is
high may result in glass breakage.

-3-
Do not disconnect any of the modules when under load.
When looking at PV modules with anti-reflection (AR) coating technology, it will be normal to see
some cells with a slight color difference at different angles. Modules with LRF(light reflective film)
and without LRF should not be built in the same array or roof.
Connector of junction box can not be contacted with oily substances, for example, lubricant, rust
inhibitor etc.
The maximum altitude the PV module is designed for ≤ 2000m.
The maximum irradiance is 1300W/m2for module with transparent rear.
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.
2. Installation
2.1 Installation Safety
Always wear protective head gear, insulating gloves and safety shoes (with rubber soles).
Keep the PV module packed in the carton until installation.
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 rain, snow or windy conditions.
Due to the risk of electrical shock, do not perform any work if the terminals of the PV module are wet.
Use insulated tools and do not use wet tools.
When installing PV modules, do not drop any objects (e.g., PV modules or tools).
Make sure flammable gasses are not generated or present near the installation site.
Insert module connectors fully and correctly. An audible "click" sound should be heard. This sounds
confirms the connectors are fully seated. Check all connections.
The module leads should be securely fastened to the module frame, Wire Management should be
