### Electrical Safety <a href="#toc20715" id="toc20715"></a>

#### Grounding Requirements <a href="#toc29791" id="toc29791"></a>

1\.        Equipment grounding impedance should meet local electrical standards.

2\.        When you install the product, install the protective ground wire first. When you disassemble it, remove the protective ground wire in the last step.

3\.        The system should be permanently grounded. Before you operate on the system, you must check the electrical connections of the system to ensure that it is reliably grounded.

4\.        It is prohibited to operate the equipment without installing the grounding conductor.

5\.        Do not damage the grounding conductor.

<div align="left"><figure><img src="/files/gnVkwOzhQED90AuZldaE" alt="" width="128"><figcaption></figcaption></figure></div>

**It is strictly prohibited to install the system before grounding.**

#### Cabling Requirements <a href="#toc17630" id="toc17630"></a>

1\.        Cable selection, erection, and routing must comply with local laws, regulations, and specifications.

2\.        During power cable laying, loops and twists are strictly prohibited. If the cable length is insufficient, replace the cable. Making joints or solder points within the power cable is strictly prohibited.

3\.        All cables must be securely connected, well insulated, and of appropriate specification.

4\.        Cable trays and cable entry holes must have no sharp edges. Cable entry points through conduits or holes must be protected to prevent cables from being damaged by sharp edges or burrs.

5\.        Cables used in high-temperature environments may be subject to insulation layer aging and damage. Ensure that the distance between the cable and any surrounding heating devices or heat source areas is at least 30 mm.

6\.        Similar cables should be bundled together, while different types of cables must be laid at least 30 mm apart. Wrapping or crossing cables is prohibited.

7\.        All cables used in the product must be securely connected, properly insulated, and meet the applicable specifications.

8\.        Buried cables need to be reliably fixed using cable supports and cable clamps. Cables in backfilled soil areas must fit tightly to the ground to prevent deformation or damage due to force during backfilling.

9\.        At very low temperatures, severe impact or vibration may cause the plastic sheath of cables to become brittle and crack. To ensure construction safety, the following requirements must be met:

· All cables should be laid and installed at temperatures above 0°C. Handle cables gently during transportation, especially during construction in low-temperature environments.

· If the storage environment temperature of cables is below 0°C, they must be moved to room temperature storage for more than 24 hours before laying.

<div align="left"><figure><img src="/files/319vJ68EFaooyRVusfZ3" alt="" width="128"><figcaption></figcaption></figure></div>

**The system's operating temperature range is -20°C to 50°C.**

**When using the M38314-SNW battery or M38280-SNW battery, the operating temperature of the system should be between 0°C and 50°C.**

#### Working at Heights Safety <a href="#toc4479" id="toc4479"></a>

1\.        When electrical work at heights is possible, use wooden ladders or insulated ladders.

2\.        Prioritize using platform ladders with guardrails for work at heights; step ladders are prohibited.

3\.        Before using a ladder, confirm it is intact, its load capacity meets requirements, and overloading is strictly prohibited.

4\.        The ladder must be placed on a stable surface and must be held by someone during operation.

5\.        When climbing the ladder, keep your body steady and ensure your center of gravity does not deviate from the edge of the ladder frame to reduce danger and ensure safety.

6\.        When using an A-frame ladder, the spreader rope must be secure.

### Environmental Requirements

#### General Requirements <a href="#toc22982" id="toc22982"></a>

1\.        Do not place the equipment in an environment containing flammable or explosive gases or smoke, and do not perform any operations in such an environment.

2\.        Do not store flammable or explosive materials in the equipment area.

3\.        Do not place the equipment near heat sources or ignition sources, such as fireworks, candles, heaters, or other heat-generating devices. Exposure to heat may cause damage to the equipment or result in fire.

4\.        The equipment shall be installed in an area away from liquids. Do not install it under water pipes, air outlets, or other locations where condensation is likely to occur. Do not install it under air conditioner outlets, ventilation openings, cable outlet windows in equipment rooms, or other locations prone to water leakage, so as to prevent liquid from entering the equipment and causing malfunction or short circuit.

5\.        During equipment operation, do not block the ventilation openings or cooling system, and do not cover the equipment with other objects, so as to prevent equipment damage or fire caused by overheating.

6\.        The storage environment for the equipment shall have appropriate temperature and humidity conditions. The equipment shall be stored in a clean, dry, and well-ventilated area, protected from dust and condensation.

7\.        Do not install, use, or operate outdoor equipment or cables in severe weather conditions such as lightning, rain, snow, or strong winds above Force 6, including but not limited to moving equipment, operating equipment and cables, plugging or unplugging signal interfaces connected to the outdoors, working at height, outdoor installation, or opening doors.

#### 1.1.2   Mounting Environment Requirements <a href="#toc4276" id="toc4276"></a>

1\.        StaX-M29.9，Stax-M30，StaX-M50 are suitable for indoor and outdoor installation.

2\.        Do not install the inverter in a place where people can easily touch it because the inverter’s surface will get extremely hot during operation.

3\.        Do not engage screws into tapped holes using a Hammer Driver, Impact Driver or “Rattle gun”. Do not damage screws or threaded holes by tightening with too much torque.

4\.        Do not mount the system in areas with flammable or explosive materials.

5\.        Do not install the system in outdoor areas where there may be high salt fog, as corrosion may cause damage there. The overall anti-corrosion grade of the system is C4. Please determine the installation area according to the C4 standard.

6\.        The system must be mounted in a well-ventilated environment to ensure adequate heat dissipation.

7\.        Do not mount in a location that will be exposed to direct sunlight. When mounted under direct sunlight, the power of the system may be derated due to additional temperature rise and the longevity of the product will be reduced.

8\.        Mount the system in a sheltered place or mount an awning over it.

9\.        The optimal temperature range for the battery to operate is 15 to 30℃.

10\.     Favour locations that are indoors, under cover, or generally protected from the elements and extreme temperatures (e.g. in a garage).

11\.     Do not place the system near water sources such as downpipes or sprinklers.

12\.     If the battery is mounted in the garage, ensure the product is adequately protected from potential mechanical impact.

#### 1.1.3   Mounting Structure Requirements <a href="#toc205283426" id="toc205283426"></a>

1\.        The surface to which the Battery System is to be mounted shall be fire-rated where required by local regulations.

2\.        Out of an abundance of caution, it is recommended that the system be mounted on non-flammable building materials, even when not required by local regulations.

3\.        Ensure that the mounting surface is sufficiently sturdy to bear the weight of the Product. Before installation, use stud finder to find the stud behind the plaster wall for fixing the base and battery.

4\.        In residential installation, do not mount the system on drywalls or walls made of gyprock or similar materials with poor sound insulation. The noises generated by the inverter can be noticeable and may be exacerbated by locations with poor insulation or where echoing may occur.

#### Space Requirements

**Reserve sufficient space around the energy storage system to ensure sufficient space for installation, maintenance and heat dissipation.**
