facilities, working at heights, and performing outdoor installation) in harsh
weather conditions such as lightning, rain, snow, and level 6 or stronger wind.
● After installing the equipment, remove idle packing materials such as cartons,
foam, plastics, and cable ties from the equipment area.
● In the case of a re, immediately leave the building or the equipment area,
and turn on the re alarm bell or make an emergency call. Do not enter the
building on re in any case.
● Do not scrawl, damage, or block any warning label on the equipment.
● Tighten the screws using tools when installing the equipment.
● Understand the components and functioning of a grid-tied PV power system
and relevant local standards.
● Repaint any paint scratches caused during equipment transportation or
installation in a timely manner. Equipment with scratches cannot be exposed
to an outdoor environment for a long period of time.
● Do not open the host panel of the equipment.
Personal Safety
● If there is a probability of personal injury or equipment damage during
operations on the equipment, immediately stop the operations, report the
case to the supervisor, and take feasible protective measures.
● Use tools correctly to avoid hurting people or damaging the equipment.
● Do not touch the energized equipment, as the enclosure is hot.

User Manual 1 Safety Information
Issue 02 (2020-10-30) Copyright © Huawei Technologies Co., Ltd. 2

● Only professionals or authorized personnel are allowed to replace the
equipment or components (including software).
NO TE
● Professionals: personnel who are trained or experienced in equipment operations
and are clear of the sources and degree of various potential hazards in equipment
installation, operation, and maintenance
● Trained personnel: personnel who are technically trained, 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
● Operators: operation personnel who may come in contact with the equipment,
except trained personnel and professionals
1.3 Electrical Safety
Grounding
● For the equipment that needs to be grounded, install the ground cable rst
when installing the equipment and remove the ground cable last when
removing the equipment.
● Do not damage the ground conductor.
● Do not operate the equipment in the absence of a properly installed ground
conductor.
● Ensure that the equipment is connected permanently to the protective
ground. Before operating the equipment, check its electrical connection to
ensure that it is securely grounded.
General Requirements
D ANGER
Before connecting cables, ensure that the equipment is intact. Otherwise, electric
shocks or re may occur.
● Ensure that all electrical connections comply with local electrical standards.
● Obtain approval from the local electric utility company before using the
equipment in grid-tied mode.
● Ensure that the cables you prepared meet local regulations.
● Use dedicated insulated tools when performing high-voltage operations.
AC and DC Power
D ANGER
Do not connect or disconnect power cables with power on. Transient contact
between the core of the power cable and the conductor will generate electric arcs
or sparks, which may cause re or personal injury.
SUN2000-(196KTL-H0, 200KTL-H2, 215KTL-H0)
User Manual 1 Safety Information
Issue 02 (2020-10-30) Copyright © Huawei Technologies Co., Ltd. 3

● Before making electrical connections, switch o the disconnector on the
upstream device to cut o the power supply if people may contact energized
components.
● Before connecting a power cable, check that the label on the power cable is
correct.
● If the equipment has multiple inputs, disconnect all the inputs before
operating the equipment.
Cabling
● When routing cables, ensure that a distance of at least 30 mm exists between
the cables and heat-generating components or areas. This prevents damage
to the insulation layer of the cables.
● Bind cables of the same type together. When routing cables of dierent types,
ensure that they are at least 30 mm away from each other.
● Ensure that the cables used in a grid-tied PV power system are properly
connected and insulated and meet specications.
1.4 Installation Environment Requirements
● Ensure that the equipment is installed in a well ventilated environment.
● To prevent re due to high temperature, ensure that the ventilation vents or
heat dissipation system are not blocked when the equipment is running.
● Do not expose the equipment to ammable or explosive gas or smoke. Do
not perform any operation on the equipment in such environments.
1.5 Mechanical Safety
Using Ladders
● Use wooden or berglass ladders when you need to perform live working at
heights.
● When a step ladder is used, ensure that the pull ropes are secured and the
ladder is held rm.
● Before using a ladder, check that it is intact and conrm its load bearing
capacity. Do not overload it.
● Ensure that the wider end of the ladder is at the bottom, or protective
measures have been taken at the bottom to prevent the ladder from sliding.
● Ensure that the ladder is securely positioned. The recommended angle for a
ladder against the oor is 75 degrees, as shown in the following gure. An
angle rule can be used to measure the angle.

● When climbing a ladder, take the following precautions to reduce risks and
ensure safety:
– Keep your body steady.
– Do not climb higher than the fourth rung of the ladder from the top.
– Ensure that your body's center of gravity does not shift outside the legs
of the ladder.
