3. General Safety Rules
The mechanical and electrical installation of modules should refer to the relevant rules and
regulations, including Electrical Code, Architecture Law and power connection requirements. All
these rules may be different due to all the changes of installation locations, installation system
voltages and whether using DC or AC, so please contact the local authorized organizations for
detailed rules and get the corresponding permit. The installer should comply with all the safety
protections in this manual and the local rules.
Under normal working conditions, the parameters such as power, current and voltage may be
different from the values stated on the labels which are tested under standard conditions.
Accordingly, when designing the rated voltage, current, fuse and controller of the modules or
system-matched components, the short circuit current(Isc) and open circuit voltage(Voc) stated on
the module label should be multiplied by the coefficient 1.25.
It is forbidden to use modules with different structures in one system. PV system can only use
the PV specialized equipment such as inverters, connectors, cables and brackets. The integrated
night PID recovery inverter is recommended to avoid the power station PID problem. The installer
should read and comply with all the installation and safety cautions of all the other components of
the system, including the electric wire, connector, DC switch, fixed device, inverter, rechargeable
batteries, etc.
3.1 Safety Cautions
The modules will generate direct current when irradiated by the sun. Touching electriferous
components is potentially dangerous. It is forbidden to touch the connectors of the junction box.
Special attention should be paid when handling and connecting wires.
It is forbidden to gather the sun to the modules with mirror or any other amplifiers. Cover the
modules completely with opaque material during the installation to avoid current generated.

be stored in the original carton before installation. Please keep the packages from damage. Do not
drop the modules which are packed in pallet. When piling the modules, please choose a flat
table-board, and do not exceed the ceiling limit which is printed on the carton. Before opening the
carton, please keep the package at a lucifugal, dry and flat place. If the modules need to be stored
before installation, please do not open the package. The package should be stored somewhere
lucifugal, draughty and away from exposure. If the modules need to be taken out of the package for
temporary storage, then they should be put on the dry and draughty pallet, and make sure the glass
side of the modules are downwards(the glass side of the bottom module should be upwards), with
maximum quantity of 30 pieces on each pallet.
When taking the modules out of the package, follow the unboxing instruction on the box.
Remove the straps and package cover, and take out the modules one piece at one time. Pay
attention to avoid the remaining modules dumped on one side during this process.
The modules are with certain weight, so do hold the frame carefully and handle with care. When
handling, please do not wear any accessory such as watch or ring to avoid scratching the modules.
Don’t jolt or crash the modules during handling or installing. Don’t put down the modules violently. It
is forbidden to pick up the modules by grabbing the junction box or the cables under any
circumstance. Don’t stand or walk on the modules. Don’t drop one module onto another one. Don’t

Design load：3600 Pa for positive (downward) and 1600 Pa for negative (upward);
Safety factors γm=1.5
The module is suggested not to be operated at the limit temperature for long time, to avoid the
untimely power attenuation and failure.
The module is suggested to be installed in the areas with altitude below 2000m. Special
electrical design by professionals is required when the altitude of the installation area is above
2000m.( with the increase of altitude, there are consequences as follow: 1. decreased air density,
worse heat dispersion, leads the product to be used with reduced capacity. 2. decreased
compression strength, the rated voltage and isolation voltage will decrease when the electrical
clearance of creepage distance is invariant. 3.reducing the product over-voltage bearing capacity,
arcing ability and breaking ability.)
Make sure the wind pressure or snow pressure after module installation will not exceed the
bearable load.
The module should be installed somewhere with sufficient sun irradiation and no shadow
perennially.
The module system need lightning protection during the installation and operation, especially
when it is installed in the area of lightning frequent activity, otherwise the module may be damaged
by the lightning.

7.1 General Installation Rules
The PV system installation requires professional knowledge and technique, and should be
installed by qualified persons with specialized and licensed installation tools.The module
installers undertake all the risk of injury including electric shock. The module installation should
abide by all the local applicable laws and regulations, including local,regional and host countries.
The construction electric installation permit should be obtained in necessity.
PV module converts light energy to direct current energy, which is specially design for
outdoor use. The modules can be installed on the ground, bracing piece or the roof. The
designer and installer of the system are responsible to design the support structure correctly.
The installation can only be operated under dry conditions with dry tools. Do not handle wet
modules, unless the carrier is wearing proper protective equipment. Please stop the installation
when it is snowy, rainy or windy.
Do not wear any metal object such as watch, ring, earring, nose ring or oral ring,etc. Please
do not touch the module with bare hands which will lead to dangers like scald or electric shock
because the surface and the frame of the glass may be very hot.
Due to the thermal expansion and contraction effect of the module frame, the distance
between two adjacent modules should be bigger than 10mm. The end of the junction box
should be installed in a relatively high place when installing.
The screw should be installed with the set mounting holes on the module frame. The most
common screw installation is with the four symmetrical mounting holes in the middle of the
module frame. Eight mounting holes are required to be all installed when the system is installed
somewhere with frequent wind and snow.
7.2 Selection of Installation Direction and Tilt Angle
A. To obtain the maximum generation efficiency, the module should be installed southward
when in the Northern Hemisphere, and northward when in the Southern Hemisphere.
B. The module can be installed lengthways or sideways. Do check whether the length of the
cable is enough when installing. If extra cables needed, do choose the cable with same type of

Jinyuan Lighting
10
connector.
C. To get the best installation tilt angle, please refer to standard PV installation manual or
consult the professional installer or system integrator for detail info. Jinyuan suggests the PV
module installation tilt angle to be above 10°, as this tilt angle will make sure the system can do
self-cleaning when it is raining.
D. The same string of modules should be installed at the same tilt angle. Otherwise with
different installation angle, the modules will absorb different irradiation and causes the
mismatching current and therefore lowers the system efficiency.
7.3 Selection of the Suitable Bracket
a) Check the instruction manual and safety cautions of the bracket which will be used for the
module installation. The designer or installer of the system should calculate and choose the
proper bracket to guarantee the load demand. The installation bracket should be made with
materials resistant to abrasion, corrosion and UV resistance.
b) Do not drill extra mounting holes on the surface or the frame of the modules, otherwise the
warranty will be invalid.
7.4 Ground Installation
Choose the proper installation height, tilt angle and distance to avoid the bottom of the
module from flooded by the rain or buried by the snow. Meanwhile, do make sure the module is
not covered by shrubs, buildings or obstructions, etc, and will not be hit and broken by the
windblown dinas.
7.5 Roof Installation
Better in calm weather for roof or building installation. Installing in gale weather may cause
safety accident.
For roof or building installation, make sure the modules are fastened safely and will not be
blown off by the wind or collapsed by the snow.
When roof installation, make sure the roof structure is suitable for installing. The system
designer needs to set up the corresponding brace beam based on the roof special structure
requirement. If it should be installed through the roof, make sure the perforation is sealed
correctly to avoid water leaking.

Jinyuan Lighting

Roof installation may affect the fireproof endurance rating of the building. The fireproof
endurance rating of the module is grade C.
Reserve at least 10cm height space between the module and the roof to make sure the
cooling of the module under working status.
7.6 Installation Method
The module has three different installation methods: install through the mounting hole(with
screws), clamp fixed installation(with clamp),and embedded installation(with frame embedded).
The installer can choose the suitable method for installation. Aluminum alloy is recommended
for clamp material.
There are 8 mounting holes with dimension 9*14mm on the frame of every module,which
are used to fasten the module to the bracket using screws.
Under any circumstance, the clamp can not contact the glass or cause the module frame
shape changing. The contact surface of the clamp and the frame should be flat and smooth.
The clamp can not cover the waterspout. The clamp can not have shelter effect on the solar
cells.

8. Electrical Installation
8.1 General Installation Rules
Normally the module may generate more electricity than standard condition. When
deciding the PV system component, with the parameters associated with rated voltage, wire
rated current, fuse model numbers and module output power,etc, do consider the actual
installation environment and conditions.
Please make sure the electrical components such as connector and inverter are in
disconnection during the installation.
Photovoltaic system can be formed with several modules in series and then in parallel,
which is especially suitable for higher voltage requirement. When the modules are in series, the
total voltage of the system is the sum total of each module voltage. And when higher current is
required, the modules can be organized in parallel, with total current of the system equal to the
sum total of each module current.
The maximum quantity for module to be in series or parallel should be calculated according
to the requirement of relevant regulations. The open circuit voltage under the expected local

Jinyuan Lighting
16
lowest temperature and maximum irradiation can not exceed the module specified maximum
system voltage DC1000V. The reference formula of maximum quantity in series is
1000V/(1.25*Voc). The reference formula of maximum quantity in parallel is max protective
current/Isc+1(the maximum protective current of Jinyuan junction box is 15A)
The over-current protection of module is used on the DC side. Please refer to the local
regulations to make sure the fuse application requirement. If there may be a reverse current
through the module which exceeds the maximum fuse current, an equivalent over-current
protection will be needed to protect the module. If the number of parallel is equal or greater than
2 strings, every string of modules should be installed with an over-current protection device.
Please choose the dimension, type and temperature requirement of cable according to the
standards of local, regional and host country. To avoid the cable and connector overheated, the
cable conductivity and connector endurance should meet the short circuit current and
temperature when the system is exposed outdoor. Jinyuan suggests that the connect cable on
site should satisfy the module to be used under the module maximum short circuit current. The
cable should be a waterproof and UV-proof cable complying with the photovoltaic DC
requirement, with sectional area 4mm2and temperature range -40 ~85 . Jinyuan module℃℃
connector is MC4 port, with male and female connectors distinguishing positive and negative
poles, which should be connected accordingly. When connecting with a third party matched
wiring device, follow the operating manual of the equipment manufacturer. Please make sure
the connector is clean,dry, in place and firm when connecting. Wrong connection or not in place
may cause a voltaic arc or electric shock. Connector should not subjected to additional pressure.
Non-professionals are prohibited to open the lock nut. The connector is only for connecting
circuit without opening or closing circuit function.
Figure 7. Male Connector and Female Connector

The PV system should be installed with lightning protection device where there is frequent
lightning activity. To reduce the risk of lightning stroke, the minimum loop area should be applied
when laying the cable.
Figure 8. Circuit Design
When the cables are fixed on the bracket, it is necessary to avoid the mechanical damage
of the cable or the module. Do not press the cable.when fixing cable in a proper way, it should
be fixed with light-resistant cable ties, and avoid direct sunlight and water soaking.
8.2 Grid Electrical System
The DC current of PV system can be converted to AC and connected to the public supply
network. As the policies in different area about connecting PV system to public supply network
are different, please consult the senior system design engineer when designing. Usually, the
installation of this system will need the recognition,acceptance and formal approval of the public
utilities.
8.3 Equipotential Connection
In order to avoid the risk of electric shock or fire hazard, the module frame needs to do the
equipotential connection before the system operation. Please refer to the local safety and
electrical installation standard for the installation requirement.
The correct grounding device is to connect all the metal devices which is not used for

Jinyuan Lighting
18
conducting to the grounding device with proper dimension or to a bracket as an integrated
grounding device. There are grounding hole(Ø4) and grounding mark on the aluminum frame,
which are not used for fixing module. Extra holes are prohibited to be drilled on the module.
Grounding screws, spacers and nuts should be stainless steel material. Bend the
grounding wire into shape Ωand fix it between the screw head and spacers. Grounding screw
penetrates the grounding hole. The toothed lock washer should be installed to penetrate the
anodic oxide film of the aluminum frame to make sure a safe and reliable grounding effect.

Figure 9 Equipotential Connection Diagram
The PV module can do the grounding with modules connected to the bracket as an
integrated grounding device or additional ground equipment. But all these grounding measures
should be safe and effective, and can not cause the electrochemical corrosion between the
aluminum frame of the module and the other different metals.
In order to obtain the best output power and avoid the PID effect, the DC negative of the
module array should be earthed when installing the modules. If this rule is not followed during
the installation, the output power of the system may be lowered.
Joint the module with field installation equipotential connection conductors and grounding
conductors. The connector or junction of the module should be marked with below special
identifier, any other connector or junction can not use this symbol

9.Commissioning and Maintenance
1) It is suggested to have the mechanical and electric checking at least once every six months
to make sure the module and system connectors are clean and connected reliably. Pay
attention to comply with all the maintenance manuals of all the components used in the system,
including bracket, inverter, junction box and battery, etc.
2)There may be accumulated dirt and dust on the surface of the modules as time goes on,
which will lower the output power of the module. It is suggested to clean the module at least
once every year to make sure the maximum output power, especially in the areas with low
rainfall. Please choose the time with not strong sunlight for the module cleaning.
3) Please do not touch or handle the glass surface of the module with bare hands to avoid
leaving the fingerprint or any other dirt on the glass. When cleaning the module surface, firstly
use a dry duster or cloth to brush off the surface adhesive materials, and then clean with wet
soft sponge or cloth. Mild cleaning agent without abradant can also be used to get rid of the
dirties.
4) When cleaning, do not use the water with high mineral content, do not use the water with big
water pressure. Normal municipal water supply is enough.
5)If the module is installed somewhere with more sand-dust, it is suggested to blow the sand
with gas. If there is snow cover on the module surface , please do not try to remove the frozen
snow or ice with brute force.
6) Please do not clean the modules with damaged glass or bare wire, otherwise there will be
risk of electrical shock.
7)If there is any question, please arrange qualified person for checking.
