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 specications.

WARNING
During operations, wear personal protective equipment such as protective
clothing, insulated shoes, goggles, safety helmets, and insulated gloves.
Figure 1-1 Personal protective equipment
General Requirements
● Do not stop protective devices. Pay attention to the warnings, cautions, and
related precautionary measures in this document and on the equipment.
● If there is a likelihood of personal injury or equipment damage during
operations, immediately stop, report the case to the supervisor, and take
feasible protective measures.
● Do not power on the equipment before it is installed or conrmed 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
aected building or equipment area under any circumstances.
Personnel Requirements
● Only professionals and trained personnel are allowed to operate the
