Avoid partial shading of PV modules for a long
period of time, otherwise the temperature of the
shaded module may rise due to hot spot effect,
burning the module and causing fire hazard in
severe cases.
For PV modules used in deserts or windy and
sandy areas, it is recommended to use connector
dust caps before installation, or take other measures
to prevent sand and dust from entering the
connectors, otherwise it may cause insertion
problems or electrical safety hazards.
3.2
Operation safety measures
Avoid package damaging and falling during
transportation and storage. Ensure the packing
cases are well ventilated, water-proof and dry.
After the arrival, carefully open the outer package
and prevent scratches and bumps of PV modules.
When stacking PV modules, strictly follow the
stacking requirements in chapter 4.3.
Avoid impact or scratches on any part of the PV
module, otherwise the reliability and safety of the
PV module will be affected; standing or walking on
the PV module is prohibited; at the same time, in
order to avoid glass damage, it is forbidden to
apply excessive load or distorted PV modules.
Do not install or carry PV modules by one person.
It is forbidden to pick up, drag, or move PV
modules by grabbing the junction box (including
the box body, cables, and connectors); when
placing a PV module on a flat surface, it must be
operated carefully and be aware of bumps in the
corners.
When installing or repairing the PV system, do not
wear any metal accessories to avoid the risk of
electric shock; if it is installed far above the ground,
please wear a seat belt.
When operating PV modules in the sun, please use
insulated tools, and wear rubber gloves and
protective clothing. At the same time, in order to
avoid the risk of arc and electric shock, do not
directly touch the junction box and the end of the
output cable (connector) with bare hands.
For electrical connection, choose a dry and
weak-light morning or evening; or use opaque
materials to completely cover the surface of the PV
modules to prevent current generation.
A certain distance between the PV module and the
installation surface should be kept to prevent the
installation surface from touching the junction box.
When installing on the roof, comply with the fire
protection requirements of the building. It is
recommended to install PV modules on a fireproof
and insulated roof covering, and ensure adequate
ventilation between the PV modules and the
installation surface. In order to ensure the fire
rating on the roof, the minimum distance between
the frame of the PV module and the roof surface is
10cm.
The connector must be fully mated when wiring. If
the cable is too long, it is recommended to fix the
cable to the rack system with a UV-resistant nylon
cable tie. When fixing the cable to the rack, the
bending radius of the cable should not be less than
48mm.
Avoid directly exposing cables and connectors to
sunlight. Please use anti-UV cables.
