Comply with applicable laws, regulations, standards, and specications during

transportation, storage, installation, operation, use, and maintenance.

Do not perform reverse engineering, decompilation, disassembly, adaptation,

implantation, or other derivative operations on the equipment software. Do not

study the internal implementation logic of the equipment, obtain the source code

of the equipment software, violate intellectual property rights, or disclose any of

the performance test results of the equipment software.

The Company shall not be liable for any of the following circumstances or

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.

SUN2000-(8K, 10K)-LC0 Series

User Manual 1 Safety Information

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 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.

Personnel Requirements

● Only professionals and trained personnel are allowed to operate the

equipment.

– Professionals: personnel who are familiar with the working principles and

structure of the equipment, trained or experienced in equipment

operations and are clear of the sources and degree of various potential

hazards in equipment installation, operation, maintenance
