SAFETY

2.1 GENERAL SAFETY

• The PV modules are qualified for application class A, which may be used in systems operating at greater than 50 V DC or 240 W, where general contact access is anticipated. PV modules qualified for safety through this part of IEC 61730 and IEC 61730-2 and within this application class are considered to meet the requirements for safety class II.
• The PV modules shall be properly grounded in accordance with the instructions in this Guide or the requirements of the National Electrical Code.
• Installing PV modules requires specialized skills and knowledge. Installation should only be performed by qualified personnel, electrical connections requires a licensed electrician , where applicable according to local code and law (i.e. the NEC for the USA and CEC for Canada).
• Installers should assume all risks of injury that might occur during installation, including, but not limited to, the risk of electric shock.
• One single PV module may generate more than 30V DC when exposed to direct sunlight. Access to a DC voltage of 30V or more is potentially hazardous.
• PV modules convert light energy to DC electrical energy, which are designed for outdoor use. PV modules can be mounted onto ground, rooftop, vehicles or boats etc. The proper design of support structures lies within responsibility of the system designers and installers.
• Do not use mirrors or other magnifiers to concentrate sunlight onto the PV modules.
• When installing the PV modules, abide to all local, regional and national statutory regulations. Obtain a building permit if necessary.
• Only use equipment, connectors, wiring and support frames compatible with the PV modules.
• Do not clean the modules with chemicals.

2.2 HANDLING SAFETY

• Do not lift the PV module by grasping the module’ s junction box or electrical leads.
• Do not stand or step on the PV modules or place heavy objects onto it.
• Do not drop the PV module or allow objects to fall on the PV module.
• Do handle with care when move, transport and install the PV modules.
• Do not attempt to disassemble the PV modules, and do not remove any attached nameplates or components from the PV modules.
• Do not apply paint or adhesive to the PV module top surface.
• Do not scratch or hit the back sheet.
• Do not drill holes in the frame. This may reduce the frame mechanical strength and cause crack cells due to vibration.
• Do not break the anodized coating of the frame (except for grounding connection), this may cause corrosion of the frame.
• Do not use PV modules with broken glass or torn back sheet which has danger of electrical shock.
• Do not handle panels in wet condition unless has appropriate protection.
• Do not expose PV module to sunlight until installation to avoid unnecessary degradation.
• During all the transportation, please make sure there is no strenuous vibration on module. Because it may cause cell micro crack or damage the module.

2.3 INSTALLATION SAFETY

• Installation shall be in conformity with IEC standard, Safety Standard for Electrical Installations.
• Do not disconnect under load.
• Do not touch conductive parts of PV modules, such as terminals which can result in burns, sparks and lethal shock whether or not the PV module is connected.
• Do not touch the PV module unnecessarily during installation.
• Do not work in the rain, snow or windy conditions.
• Do not expose the artificially sunlight to PV modules. Completely cover the PV module with an opaque material during installation to prevent electricity from being generated.
• Do not wear metallic rings, watchbands, ear, nose, lip rings or other metallic objects while installing or troubleshooting.
• Only use insulated tools that are qualified for working on electrical installations.
• Follow the safety regulations for all other system components, including wires and cables, connectors, charging regulators, inverters, storage batteries, rechargeable batteries, etc.
• Under normal outdoor conditions the current and voltage generated will differ from those listed on the datasheet. When design systems, current and short-circuit current should be multiplied by a factor of 1.25 to determine components ratings.
• Only use connectors compatible with the PV module connectors. Removing the connectors without prior authorization will invalidate the warranty.
• Do not dismantle installed modules to another project, which may invalidate the warranty.
• Do not install modules within 50m of the shoreline

2.4 FIRE SAFETY

• The fire rating of this module is valid only this Guide is followed.
• Consult your local authority for Guidelines and requirements for building or structural fire safety.
• Do not use PV modules near equipment or in places where flammable gases may be generated.
• Follow local codes and laws when install the modules

MECHANICAL INSTALLATION

4.1 GENERAL INSTALLATION PRINCIPLE

• Module can be installed in both landscape and portrait modes 1
• It is recommended to install the same size and the same type of module in one PV array.
• The PV modules shall be installed high enough to keep it away from potential shading, flying sands, snow and water.
• It is recommended to install the PV modules 30cm away from the ground to make sure ventilation.
• Appropriate installation structures shall be chosen to meet required mechanical load.
• It is recommended to install the PV modules with minimum angle of 10 degree to make the dust easily to be washed off.
• It is recommended to keep minimum 10mm gap between PV modules for thermal expansion of materials.
• Install PY modules appropriately according to corresponding mechanical load need.

4.2 LOCATION AND ANGLE SELECTION
It is recommended to install PV modules where has excellent sunlight resources. In the Northern Hemisphere, the module should typically face south, and in the Southern Hemisphere, the modules should typically face north. The most optimistic installation angle varies according to different latitudes and longitudes; please consult experts with appropriate knowledge background when determining the installation locations and angles.
When choosing a site, avoid trees, buildings or obstructions, which could cast shadows on the solar photovoltaic modules. Shading causes hotspot and loss of output, even though the factory fitted bypass diodes of the PV module will minimize such effect.
Do not install the PV module near naked flame or flammable materials.
Do not install the PV module in a location where it would be immersed in water or constantly exposed to water from a sprinkler or fountain etc.
4.3 SCREW INSTALLATION
Each PV module has 8 mounting holes(shown as drawing1-1).The downward mechanical load resistance of module would be different according to the installation holes used(shown as table1-1)Please use 8 of them tosecure the modules to support structure. The module frame must be attached to a mounting rail using M8 corrosion-proof screws together with spring washers and flat washers in eight symmetrical locations on the PV module. M6 bolts are used when installing with 4 Nextracker mounting holes.The applied torque should be big enough to fix it steadily.The reference torque value for M8 screw is 16~20N*m.

For 210 and 182 partial modules, four mounting holes are used for the frame in the standard industry, so as to facilitate customer installation.We used four mounting holes in the frame of 210 and 182 partia modules (shown on drawing 1-2).

TABLE 1 -2
4.4 CLAMP INSTALLATION
The modules can be fixed on both the long and the short side of the module within the constraints shown in drawing2 and drawing3,using a minimum of four clamps. The modules are built to withstand a downward force of up to 5400 Pa (550 kg/m2) or 2400 Pa (244 kg/m2) according to where they are clamped(shown as table2 and table3),Site-specific loads such as wind or snow which may exert forces in a different way need to be taken into consideration to ensure this limit is not exceeded for each respective mounting option. It is recommended to use a fixture that can hold the M8 bolt at least, with corresponding spring gaskets

• DO NOT damage or scratch the rear surface of the module.
• DO NOT handle or install module when they are wet.

The wiring components shall be compatible with the PV modules.
The PV modules connected in serial shall have similar current. The Voc of one PV string shall no higher than the maximum system voltage(make reference to the maximum system voltage marked on label), the Voc temperature coefficient feature and the extreme low temperature of installation location must be taken into consideration when calculate the Voc of the PV string .
The PV modules connected in parallel shall have similar Voltage. The Isc temperature coefficient feature and the extreme high temperature of installation location must be taken into consideration when calculate the Isc of the PV array.
Please refer to local regulations to determine the system wires size, type and temperature.
The cross-sectional area and cable connector capacity must satisfy the maximum short-circuit of PV system (For a single component, we recommended the cross- sectional area of cables is 4mm2 and the the rated current of connectors is more than 15A), otherwise cables and connectors will become overheating for large current. Please pay attention: the temperature limit of cables is 85 ° C and the temperature limit of connector is 105°C A qualified system designer or integrator should always be consulted.
Building permits, inspections and approvals by the local utility are generally required.
Before installation, make sure that the connector is well protected and there should be no foreign matter such as soil, sand and gravel in the connector. If any, it must be cleaned before installation. If the connector is damaged or deformed, the connector must be replaced before use; if there is no spare connector, please contact seraphim in time.
When the customer makes a series circuit connection, it is necessary to use the connector of the same module as the component. If necessary, the connector on the module can be cut off and replaced with the customer’s connector.
Remark: If conversion cable is needed, see attachment! for details.
4.6 GROUNDING
Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock washers, flat washers and the like) is used to attach a listed grounding/bonding device, the attachment must be made in conformance with the grounding device manufacturer’ s instructions.
For grounding and bonding requirements, please refer to regional and national safety and electricity standards. If grounding is required, use a recommended connector type, or an equivalent, for the grounding wire.
If grounding is required, the grounding wire must be properly fastened to the module frame to assure adequate electrical connection (grounding hole shown as drawing 4).
PHOTOVOLTAIC MODULE
When system operates in high humidity and high temperature circumstances ,transformer-Based inverter allowing system negative grounding is highly recommended to achieve mitigating risk of higher power degradation rate.
