  The “CAUTION”, “WARNING” and “DANGER” marks in this document do not represent all the safety instructions. They are only supplements to the safety instructions.

1. Local Safety Regulations
   When operating the equipment, you must follow the local laws and regulations. The safety instructions in this document are only supplements to the local laws and regulations.

2. Personal Requirements

   • Only trained and qualified personnel are allowed to install, operate, and maintain BITMAIN equipment, and they must understand basic safety precautions to avoid hazards.
   • Only trained and qualified personnel are allowed to install, operate, and maintain BITMAIN equipment.
   • Only personnel certified or authorized by the equipment provider are allowed to replace or change the equipment or components (including software).
   • Any fault or error that might cause safety problems must be reported immediately to a supervisor.

3. Grounding Requirements
   Equipment to be grounded must meet the following requirements:

   • When installing the device, always make the ground connection first and disconnect it at the end.
   • 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.

4. Personal Safety

   • Keep irrelevant people away from the equipment. Only operators are allowed to access the equipment.
   • Before operating a device, wear insulated shoes and insulated gloves, and pay attention to eye protection. Remove conductive objects such as jewelry and watches to avoid electric shocks or burns.
   • Ensure that tool handles are insulated.

5. Equipment Safety

   • Do not block the ventilation while the device is operating.
   • Tighten the screws by using a tool after initial installation and subsequent access to the panel.
   • After the installation, remove packing materials from the equipment area.

Electrical Safety

1. High Voltage
   Danger
   The high-voltage power supply provides power for the operation of the equipment. Direct contact or indirect contact with the high-voltage power supply through wet objects (or conductors) is fatal. Irregular and incorrect high-voltage operations may cause accidents such as fire or electric shock. Signal wires should be tied separately from high-current wires or high-voltage wires.

2. High Electrical Leakage
   Danger

3. Before timing on se postal all component safety willie endanger the general grounding wire must

4. If a “large leakage current” sign is pasted near the power terminal of the equipment, the protective grounding terminal of the equipment chassis must be grounded before connecting to the AC input power supply to prevent the equipment’s leakage current from causing electric shock to the human body.

5. Exposed cables in the equipment should be insulated immediately.

6. Power Cable
   Danger
   It is prohibited to install or remove the power cord while the power is on. The moment the power cord core comes into contact with a conductor, arcs or sparks will occur.

   • Before installing or removing a power cable, turn off the power switch.
   • Before connecting a power cable, check that the label on the power cable is correct.
   • If the power cable is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons to avoid a hazard.
   • The appliance should fit with means for disconnection from the supply mains having a contact separation in all poles that provide full disconnection under overvoltage category III conditions, and these means must be incorporated in the fixed wiring under the wiring rules.

Mechanical Safety

1. Drilling Holes
   Warning
   It is prohibited to drill holes in the cabinet by yourself. Drilling holes that do not meet the requirements will damage the internal components or pipelines of the equipment and damage the internal cables.
   

2. Sharp Objects
   The fins of the heat exchanger of dry tower are extremely sharp. Please wear protective gloves when operating close to the fins.
   Warning
   When carrying the equipment by hand, you should wear protective gloves to prevent your hands from being cut by the sharp corners of the equipment.

3. Fan

   • When replacing a component, place the component, screws, and tools in a safe place. Otherwise, if any of them fall into the operating fans, the fans may be damaged.
   • When replacing a component near fans, do not insert your fingers or boards into the operating fans until the fans are switched off and stops running.

4. Moving Heavy Objects
   Warning

5. Please wear protective gloves when carrying heavy objects to avoid scratching your hands.

6. When carrying heavy objects, be prepared to bear the weight to avoid being crushed or sprained by heavy objects.

7. When pulling the equipment out of the cabinet, be careful because the equipment installed on the cabinet may be unstable or heavy to avoid being crushed or hit.

8. It is prohibited for one person to carry heavy equipment alone. When transporting the device, do not tilt the device more than 15° (relative to vertical).

9. When moving or lifting the equipment, please protect the equipment to avoid scratches or bumps.

10. When transporting, it is strictly prohibited to use the components as a supporting point to prevent damage to the components.

Operation Safety

1. High Temperature and Pressure
   Misoperations may occur over high pressure, which may result in an eruption of coolant. Pay attention to high-pressure parts: exhaust valves and drain valves.

2. High-Speed Running
   Pay attention to the high-speed running part: fan.

Others

1. Binding Signal Cables
   Caution
   Bundling signal wires should be bundled separately from high-current wires or high-voltage wires.

2. Laying Out Power Cables

3. When the temperature is very low, a violent strike or vibration may damage the power cable sheathing. To ensure safety, comply with the following requirements:

4. Power cables can be laid or installed only when the temperature is higher than 0˚C.

5. Before laying out power cables that have been stored at a temperature lower than 0˚C, move the power cables to an environment of the ambient temperature and store them at the ambient temperature for at least 24 hours.

6. Handle power cables with caution, especially at a low temperature. Do not drop the power cables directly from the vehicle.

7. Storage

   • Do not store devices near a heat source or under direct sunshine.
   • Keep devices away from fire or high-temperature objects, especially devices injected with pressurized nitrogen or refrigerant; otherwise, explosion or refrigerant leakage may occur, causing personal injury.

8. Recovery and Disposal
   The sign indicates that the product cannot be disposed of with other wastes that have a shell in European Union (EU) areas. To prevent possible harm to the environment or human health from uncontrolled waste disposal, recycle it responsibly to promote the sustainable reuse of material resources.

Antifreeze Product Introduction

Appearance of Antifreeze
The following is the appearance of the antifreeze product packaging.

Antifreeze Product Parameters

Table 3.1 Antifreeze product parameters

Correspondence Between Antifreeze Concentration and Freezing Point
When the product is used in an environment where the lowest freezing point temperature is high, to avoid heat dissipation, the antifreeze can be diluted according to the following table. To ensure the long-term reliability of the antifreeze, the minimum dilution volume concentration cannot be less than 10%.

Table 3.2 Relationship between antifreeze glycol concentration and freezing point

Antifreeze Concentration Dilution Instructions
If the antifreeze needs to be diluted, please refer to the following steps:

In the field, a container (a ton of barrels that can be used to store antifreeze) should be prepared for dilution. After the antifreeze is injected into the container according to the dilution ratio, the deionized water is added in proportion to mix evenly, and the freezing point of the diluted antifreeze is sampled and detected. Refer to Table 3.2 Relationship between antifreeze glycol concentration and freezing point. For example, if it needs to be diluted 5 times, 1 portion of antifreeze and 4 portions of deionized water are added to the container respectively, and the freezing point is tested after mixing evenly.

Caution

1. To ensure that the environment is clean and tidy during dilution, the equipment must be cleaned with deionized water ;
2. We must strictly control the dilution ratio;
3. During the dilution process, wear gloves and pay attention to personnel safety.

Please refer to the following table for the quality of deionized water used to dilute antifreeze.
