3 Site Selection Requirements

• The warranty applies when the equipment has been installed properly for its intended use and in accordance with the operating instructions.

• During actual installation, the selection of installation location should comply with local firefighting, environmental protection regulations, and

other relevant laws. The specific installation location planning should be subject to the installer or engineering, procurement, and construction
(EPC) contracts.

Installation environment

• Do not install the equipment in smoky, flammable, or explosive
environments.

• Avoid exposing the equipment to direct sunlight, rain, standing
water, snow, or dust. Install the equipment in a sheltered place.
Take preventive measures in operating areas prone to natural
disasters such as floods, mudslides, earthquakes, and typhoons.

• Do not install the equipment in an environment with strong
electromagnetic interference.

• Ensure that the temperature and humidity of the installation
environment comply with the equipment's requirements.

• The equipment should be installed in an area that is at least 500 m
away from corrosion sources that may result in salt damage or acid
damage (corrosion sources include but are not limited to seaside,
thermal power plants, chemical plants, smelters, coal plants, rubber
plants, and electroplating plants).

Installation position

• Do not tilt or overturn the equipment to ensure that it is installed
horizontally.

• Do not install the equipment in places easily touched by children.

• Do not install the equipment in places with fire or damp.

• Please keep away from the daily work and living places.

• Do not install the equipment in a sealed, poorly ventilated

location without fire protection measures and difficult access for
firefighters.

• The equipment is hot when it is running. If the equipment is
installed indoors, please ensure good indoor ventilation and avoid
significant indoor temperature rise by 3°C while the equipment is
running. Otherwise, the equipment will be derated.

• Do not install the equipment in mobile scenarios such as RVS,
cruise ships, and trains.

• You are advised to install the equipment in places that are easy
to access, install, operate, maintain status.

5

Mounting surface

• Do not install the equipment on a flammable carrier.

• The installation carrier must meet load-bearing requirements. Solid

brick-concrete structure, concrete walls is recommended.

• The surface of the installation carrier must be smooth and the
installation area must meet the installation space requirements.

• No water or electricity is routed inside the carrier to prevent drilling
hazards during equipment installation.

5.1 Recommended Routing

Do not perform operations on the equipment with power on. Before
operation, please make sure all power supplies to the equipment have
been disconnected, including but not limited to the grid side, inverter
and diesel generator power switches.

• Connect cables according to the corresponding labels to prevent
personal injury and equipment damage caused by incorrect
cable connection.

• To ensure that the inverters, loads, and the Gateway are
connected to the common ground point, connect the PE cable.

5.4 Connecting Power Grid / Backup household

loads / Inverters

In off-grid mode, the N wire in the system is short-connected to the
functional grounding wire through the relay to create a grounding
system. When earth leakage or short circuit occurs in loads, leakage
protection and overcurrent protection devices are triggered to prevent
these faults.

To ensure that the inverters, loads, and the Gateway are connected
to the common ground point, connect the PE cable.
