Installation Manual
GENERAL INFORMATION
Installing solar photovoltaic systems requires specialized skills and knowledge. The installer assumes all risk
of injury, including risk of electric shock. Module installation should be performed only by a qualified installer.
All modules come with a permanently attached junction box and 4mm²wire. Jayu Solar can provide
customers with fitted cables for ease of installation, if desired.
When disconnecting wires connected to a photovoltaic module that is exposed to sunlight, an electric arc
may occur. Arcs can cause burns, start fires or otherwise create safety problems. Exercise caution when
disconnecting wiring on modules exposed to sunlight.
Photovoltaic solar modules convert light energy to direct-current electrical energy, and are designed for
outdoor use. Proper design of support structures is the responsibility of the system designer and installer.
Do not attempt to disassemble the module, and do not remove any attached nameplate
or components. Doing so will void the warranty.
Do not use mirrors or other hardware to artificially concentrate sunlight on the module.
Safety precautions for installing a solar photovoltaic system
Solar modules produce electrical energy when light shines on the front surface. The DC voltage may exceed 30V.
If modules are connected in series, the total voltage is equal to the sum of the individual module voltages. If
modules are connected in parallel, the total current is equal to the sum of individual module current
Keep children well away from the system while transporting and installing mechanical and electrical
components.
Completely cover the module with an opaque material during installation to keep electricity from being
generated.
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 use in a solar electric systems.
Always use the same type of module within a particular photovoltaic system.
Modules rated for use in this application class may be used in systems operating at greater than 50V DC or
240W, where general contact access is anticipated. Modules qualified for safety through this part of
IEC61730 and IEC61730-2 and within this application class are considered to meet the requirements for
safety class
Ⅱ
. 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 this module should be multiplied by of 1.25 when determining component voltage ratings,
conductor current ratings, fuse sizes, and size of controls connected to the PV output.
The recommend maximum series fuse is 15A(156 module).
The modules have been evaluated for a maximum positive loading of 5400pa.
Do not wear metallic rings, watchbands, ear, nose, or lip rings, or other metallic devices
while installing or troubleshooting a photovoltaic systems.
Be sure to use appropriate safety equipment (insulated tools, insulated gloves, etc) approved
for use in electrical installations.
Application class A: meet the requirements for safety class II.
