Installation Environment Requirements
The equipment is installed outdoors. The site selection requirements are as
follows:
● The equipment is heavy. Ensure that the installation surface is solid enough to
bear the weight of the equipment.
● The site is not located in a low-lying land. The horizontal level of the site is
above the highest water level of that area in history.
● The ground is solid without spongy or soft soil, and is not prone to water
accumulation or subsidence.
● The site is located in a well-ventilated area.
● The site is far away from sources of strong variation, loud noises, and strong
electromagnetic interference.
● The site is not above any underground facilities.
● The site must be a class C or higher environment but not a class D or E
environment.
● The site is far away from dust, cooking fume, harmful gases, and corrosive,
ammable, or explosive objects.
● The site is in an open area and at least 10 m away from any obstacles in all
directions.
● The site is at least 50 m away from residential areas.
● The site temperature is within the range of –25°C to +60°C. If the temperature
exceeds 55°C, the equipment must be installed in a shaded area.
● If the equipment is installed in a place with dense vegetation, in addition to
routine weeding, harden the ground under the equipment to prevent weeds
from growing.
NO TE
● Class C environment: Outdoor areas more than 500 m away from the sea. If a site
is near a pollution source, it must be 1500–3000 m away from heavy pollution
sources, such as smelteries, coal mines, and thermal power plants; 1000–2000 m
away from medium pollution sources such as chemicals, rubber, and galvanization;

1.5 Electrical Safety
Cabling
● Do not perform any improper operations, for example, dropping cables
directly from a vehicle.
● Do not route cables through air intake or exhaust vents of the equipment.
● 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.
● When routing cables, reserve at least 30 mm clearance between the cables
and heat-generating components or areas. This prevents deterioration or
damage to the cable insulation layer.
● Select cables that comply with local laws and regulations.
● The positions where cables are routed through pipes or holes must be
protected to prevent the cables from being cut by sharp edges.
● Ensure that the cables are properly connected and insulated, and meet
specications.
● After connecting medium-voltage and low-voltage cables, secure them using
cable supports and cable clips. Ensure that the cables in the backll area are
in close contact with the ground to prevent cable deformation or damage
during backlling.
● When the temperature is low, violent impact or vibration may damage the
plastic cable sheathing. To ensure safety, comply with the following
requirements:
– Cables can be laid or installed only when the temperature is higher than
0°C. Handle cables with caution, especially at a low temperature.
– Cables stored at subzero temperatures must be stored at room
temperature for at least 24 hours before they are laid out.
Grounding
● Do not damage the ground conductor.
● Do not work on the equipment in the absence of a properly installed ground
conductor.
● 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.
● The main grounding body of the equipment must be permanently connected
to the grounding grid. Before working on the equipment, check its electrical
connections to ensure that it is reliably grounded.
Safety Requirements in Maintenance and Repair
1. Before connecting or removing cables, turn o the protection switch of the
corresponding loop.
2. Place a warning sign indicating that the switch must not be turned on at the
position where the switch resides.

is energized and ensure that the equipment is completely powered o.
4. If charged bodies are found nearby, block or wrap them with insulation plates
or insulation tapes.
5. Before performing maintenance and repair, securely connect the loop to be
repaired to the main ground loop using a ground cable.
NO TICE
● Before connecting a cable, check that the labels on it are correct.
● If the equipment has multiple inputs, disconnect all the inputs before
working on the equipment.
6. After the maintenance or repair is complete, remove the ground cable
between the loop that has been maintained and the main ground loop.
1.6 Mechanical Safety
Hoisting
● Before hoisting, check the hoisting tools. Do not use damaged or unqualied
hoisting tools.
● Before hoisting objects, ensure that hoisting tools are rmly secured onto a
xed object or wall that meets the load-bearing requirements.
● Do not drag steel ropes or hoisting tools and prevent them from bumping
into the equipment.
● During hoisting, do not stand or walk under the crane or the hoisted objects.
● Install temporary warning signs or fences to isolate the hoisting area.
● Ensure that the angle between two hoisting ropes is no more than 90
degrees.

Using Ladders
● Before using a ladder, ensure that it is intact and its load bearing capacity is
adequate. Do not load a ladder with a weight in excess of its duty rating.
● Use wooden or berglass ladders when you need to perform live-line working
at heights.
● Platform ladders with protective rails are preferred. The ladder must be
secured at the four feet and held by a person.
● When a step ladder is used, ensure that the pull ropes are secured and the
ladder is held rm by a person.
● If a straight ladder is used, the ladder must be placed in a secure place. The
recommended angle for a ladder against the oor is 75 degrees, as shown in
the following gure. An angle ruler can be used to measure the angle. 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. The ladder must
be held by another person during the operation.

2 Products Description
2.1 Overview
Functions
An STS converts low-voltage (LV) AC power generated by solar inverters into
medium-voltage (MV) AC power and feeds it into a power grid.
It is a steel-structure container that houses devices include the LV cabinet,
transformer, ring main unit, and auxiliary power supply to provide a highly
integrated power transformation and distribution solution for utility-scale PV
plants in MV grid-connection scenarios.
Networking
The STS applies to grid-connected large PV plants. A typical grid-connected PV
system consists of PV strings, SUN2000 solar inverters, switch boxes, and an STS.
