To reduce the chance of accident, please read the safety precautions very carefully before operation. The "Caution, Note, Warning, Danger" in this book and on the product do not represent all the safety points to be observed, and are only supplement to various safety points. Therefore, the installation and operation personnel must receive strict training and master the correct operations and all the safety points before operation.

When operating Emerson products, the operation personnel must observe the safety rules in the industry, the general safety points and special safety instructions specified in this book.If you purchase an outdoor power supply without SPD, you should install an SPD at the front-end of AC input, otherwise, the power supply system will generate over-voltage.

Electrical Safety

I. Hazardous voltage

Some components of the outdoor cabinet system carry hazardous voltage in operation. Direct contact or indirect contact through moist objects with these components will result in fatal injury.

Observe safety rules in the industry when installing the power supply system. The installation personnel must be licensed to operate high voltage and AC power.

In operation, the installation personnel are not allowed to wear conductive objects, such as watches, bracelets, bangles and rings.

When you spot the cabinet with water or moisture, turn off the power immediately. In moist environment, precautions must be taken to keep moisture out of the power supply system.

"Prohibit" warning label must be attached to the switches and buttons that are not permitted to operate during installation.

High voltage operation may cause fire and electric shock. The connection and wiring of AC cables must be in compliance with the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high voltage operations.

To avoid electric shock hazard for outdoor environment and outdoor equipment, the non-professionals are prohibited to operate or maintain the outdoor power supply system.

II. Tools

In high voltage and AC operation, specialized tools must be used.

III. Thunderstorm

Never operate on high voltage, AC, iron tower or mast in the thunderstorm.

In thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the equipment should be well earthed in time to avoid damage by lightning strikes.

IV. ESD

The static electricity generated by the human body will damage the static sensitive elements on PCBs, such as large-scale ICs. Before touching any plug-in board, PCB or IC chip, ESD wrist strap must be worn to prevent body static from damaging the sensitive components. The other end of the ESD wrist strap must be well earthed.

V. Short circuit

During operation, never short the positive and negative poles of the DC distribution unit of the outdoor cabinet system, or the non-earth pole of the outdoor cabinet system and the earth. The power supply system is a constant-voltage DC power device, short circuit will result in equipment burning and endanger human safety.

VI. Reverse connection

Never reverse-connect the AC input live line and neutral line, or else the system will be damaged.Check the polarity of the cable and connection terminal when performing DC live operations.

As the operation space in the DC distribution unit is very tight, please carefully select the operation space.

Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation.

Use insulated tools.

In live operation, keep the arm, wrist and hand tense, so that when the tool in operation slips, the movement of the human body and tool is reduced to a minimum.Battery

Before any operation on battery, read carefully the safety precautions for battery transportation and the correct battery connection method.

If customers prepare batteries themselves, the battery installation and maintenance should meet relevant safety standards.

Non-standard operation on the battery will cause danger. In operation, precautions should be taken to prevent battery short circuit and overflow of electrolyte. The overflow of electrolyte will erode the metal objects and PCBs, thus causing equipment damage and short circuit of PCBs.

Before any operation on battery, pay attention to the following points:

1. Remove the watch, bracelet, bangle, ring, and other metal objects on the wrist.

2. Use specialized insulated tools.

3. Use eye protection device, and take preventive measures.

2.3 Operating Theory

Heat dissipation theory for forced ventilation model outdoor cabinet

The cold air is sucked in through the front door air filter at the lower part of the outdoor cabinet. It passes through the battery compartment, user equipment and subrack power supply in turn. Finally, the hot air is discharged by the fans at the top of the outdoor cabinet. In this way, the equipment and power modules in the cabinet are cooled, as shown in Figure 1-3.

Figure 2-3 Heat dissipation access for forced ventilation model outdoor cabinet

Heat dissipation theory for heat exchanger model outdoor cabinet

A heat exchanger is fitted on the door of the outdoor cabinet. It can exchange the heat between the cold air outside the cabinet and the hot air inside the cabinet. In this way, the equipment and power modules in the cabinet are cooled, as shown in Figure 1-4.

Figure 2-4 Heat dissipation theory for heat exchanger model outdoor cabinet

Heat dissipation theory for air-condition model outdoor cabinet

An outdoor air-conditioner is fitted on the door of the outdoor cabinet to cool the cabinet. It is in this that the equipment and power modules in the cabinet are cooled. In case of air-conditioner fault or AC mains failure, the emergent ventilation units automatically startup to dissipate heat emergently, as shown in Figure 1-5.
