1.1 Personal Safety
D ANGER
Ensure that power is o during installation. Do not install or remove a cable with
power on. Transient contact between the core of the cable and the conductor will
generate electric arcs or sparks, which may cause a re or personal injury.
D ANGER
Non-standard and improper operations on the energized equipment may cause
re, electric shocks, or explosion, resulting in property damage, personal injury, or
even death.
D ANGER
Before operations, remove conductive objects such as watches, bracelets, bangles,
rings, and necklaces to prevent electric shocks.
D ANGER
During operations, use dedicated insulated tools to prevent electric shocks or short
circuits. The dielectric withstanding voltage level must comply with local laws,
regulations, standards, and specications.

feasible protective measures.
● Do not power on the equipment before it is installed or conrmed by
professionals.
● Do not touch the power supply equipment directly or with conductors such as
damp objects. Before touching any conductor surface or terminal, measure
the voltage at the contact point to ensure that there is no risk of electric
shock.
● Do not touch operating equipment because the enclosure is hot.
● Do not touch a running fan with your hands, components, screws, tools, or
boards. Otherwise, personal injury or equipment damage may occur.
● In the case of a re, immediately leave the building or the equipment area
and activate the re alarm or call emergency services. Do not enter the
aected building or equipment area under any circumstances.

– Trained personnel: personnel who are trained in technology and safety,
have required experience, are aware of possible hazards on themselves in
certain operations, and are able to take protective measures to minimize
the hazards on themselves and other people
● Personnel who plan to install or maintain the equipment must receive
adequate training, be able to correctly perform all operations, and understand
all necessary safety precautions and local relevant standards.
