During installation, the voltage of PV modules in series shall not exceed the maximum system
voltage.
It is forbidden to plug connectors of different manufacturers and models into each other.
Please do not use conventional PV modules to replace roof and wall materials.
When there is current or external current in the PV module, the PV module shall not be
connected or disconnected.
Please do not use corrosive chemicals to coat the surface of photovoltaic modules.
Please do not touch the PV module when it is wet.
3.5 Operational safety
Before the PV modules arrive at the installation site, please do not open the packaging box.
Please put the packaging box in a ventilated and dry environment.
During all handling, please ensure that the PV module will not be subject to large vibration.
Improper handling and placement may cause the glass of photovoltaic modules to break or lose
electrical performance, and lose the use value of photovoltaic modules.
Handle and install PV modules with care. In any case, it is forbidden to lift the PV module by
pulling the junction box or cable. Two or more people must hold the edge of the PV module with both
hands.
It is forbidden to step on, stand on or sit on the PV module, which will damage the PV module
and pose a risk of injury to people.
It is forbidden to place any heavy object on the front and back of the PV module, and do not
place the PV module on the sharp object surface.
It is forbidden to attempt to disassemble the PV module, remove the nameplate of the PV
module or the modules on the PV module.
It is strictly prohibited to brush paint or apply any other adhesive on the surface of photovoltaic
modules.
Avoid scratching the back plate and glass surface of PV module.
It is strictly prohibited to drill holes on the frame of PV modules, which will reduce the load
resistance of the frame and lead to the corrosion of the frame, which will lead to the invalidation of
the limited warranty of PV modules.
Except for grounding, it is forbidden to scratch the anodic oxide layer on the surface of the
aluminum alloy frame, which may lead to frame corrosion and affect the load resistance and long-
