● Keep the lithium battery loop disconnected during installation and
maintenance.
● When the ambient temperature is lower than the lower limit of the operating
temperature (charge is forbidden at 0°C), do not charge the battery.
Otherwise, a short circuit would occur inside the battery.
● Do not throw a lithium battery in re.
● When maintenance is complete, return the waste lithium battery to the
maintenance oce.
1.7 PV Module Safety
If no photovoltaic (PV) module is involved, skip this section.
Before installing, operating, and maintaining PV modules, read the instructions
provided by the PV module manufacturer. The safety precautions specied in this
document are highly important precautions that require special attention. For
additional safety precautions, see the instructions provided by the PV module
manufacturer.
● Before installation and maintenance, put on a safety helmet, goggles,
insulation gloves, and protective clothing to avoid personal injury.
● Before installation and maintenance, cover all PV modules totally using opaque
materials to avoid electric shocks caused by generated currents.
● Do not 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.
● 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 case of strong wind, do not install PV modules at heights.
● To install or maintain a high support, set up a support platform and wear a
safety helmet or belt.
● Do not drill holes into, step on, or place heavy objects on PV modules,
because these actions will damage PV modules.
● At least two persons are required to move and install PV modules. Forces can
be applied only to the aluminum frame of the PV modules. 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.
1.8 DG Safety
If no diesel generator (DG) is involved, skip this section.
Before installing, operating, or maintaining a DG, read the instructions provided by
the DG manufacturer. The safety precautions
