Installation Safety
Abide by the safety regulations for all other modules used in the PV system, including
wiring and cables, connectors, controllers, inverters, storage batteries, etc., and use suitable
equipment, connectors, wiring and mounting system for a PV system. If the PV system is
used in storage batteries, the configuration with the modules should follow the advice of the
storage batteries manufacturer. The same size, the same specifications of the model can be
connected in series.
Do not install or handle the modules when they are wet or during strong wind. Keep the
junction box’s cover closed.
Damaged modules have the risk of electric shock and fire, such modules cannot be repaired
and should be replaced immediately.
When exposed to direct sunlight, one individual solar module may generate DC voltages
greater than 30 volts.
To reduce the risk of electric shock or burning, you can install modules with opaque material
on the surface of the module. The mounting of the array of modules must be carried out with
an isolating solar installation. Do not wear metal rings, watches, earrings and other metal
accessories when installing or servicing PV systems. Do not touch the electrical parts of the
module directly by hand. Use an insulated tool to make electrical connections and keep the
tool dry.
The triangular holes on the backside frame of the module are drainage holes which cannot be
blocked.
The maximum system voltage indicated in the rating label is 1500 V. During the system
Installation, the maximum open circuit voltage in series cannot exceed the maximum system
voltage.
During module interconnection, ensure to fix the connecting cables to supporting mounting
frame, so as to restrict cable movement.
Abide by the allowable minimum bending radius of the cables (suggest no less than 43mm).
Always protect the cable with conduit where there is a risk of animals or children coming into
contact with it.
Use connectors which are specially designed for photovoltaic systems, and assemble with the
tools recommended or specified by the manufacturer. In case that the connector applicable to
the solar system is required, please contact your local supplier. Only connectors of the same
type must be used.
Make sure that the polarity is correct when connecting the module with inverter, storage
battery or combiner box to avoid damage to bypass diodes in the modules due to incorrect
polarity.
Do not drill holes in the frame, this may reduce the mechanical load ability and cause
corrosion of the frame.
Do not scratch the anodized coating of the frame (except for grounding connection), this may
cause corrosion of the frame or reduce the mechanical load ability.
Modules can’t be used to replace the roof and wall materials, partial replacement is not
allowed.
Any part (including nameplate) of modules supplied by Perlight Solar Co., Ltd can’t be
dismantled without permission.
