When handling lithium batteries, do not place them upside down, tilt them, or bump
them against the ground.
Keep the battery loop disconnected during installation and maintenance.
When the ambient temperature is lower than the lower limit of the operating temperature,
do not charge the battery (0° C Charging is not allowed). Otherwise, a short circuit occurs
inside the battery.
Do not throw a lithium battery in fire.
When maintenance is complete, return the waste lithium battery to the maintenance
office.
Before installation and maintenance, put on a safety helmet, goggles, insulation gloves,
and protective clothing to avoid personal injury.
Before installing and maintaining PV modules, cover all PV modules totally using opaque
materials to avoid electric shocks caused by generated currents.
Never focus sunlight on PV modules using a mirror or lens, because this may damage PV
modules and cause personal injury.
When moving PV modules, do not hold connection boxes or power cables, because they
are not designed to support the weight of PV modules.
Exercise caution when moving PV modules to avoid collision. Improper movement and
placement may cause the glass plates on PV modules to break and lose electrical
performance, which renders the PV modules useless.
In strong wind, do not install PV modules at heights.
To install or maintain a high support, you must set up a support platform and use a safety
helmet or safety belt.
Do not drill holes in, step on, or place heavy objects on PV modules, because these
actions may damage PV modules.
At least two persons are required to move and install PV modules. Only the aluminum
frame of the PV modules can be raised. Exerting force on the front or rear surface of the
PV modules using your head is prohibited. This may cause hidden cracks in the PV
modules.
