Emerson 48330 user manual Battery

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.

4. 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 elements. The other end of the ESD wrist strap must be well earthed.

5 Short-circuit

During operation, never short the positive and negative terminals of the MFU of the system or the non-earthing terminal and the earth. The power system is a constant voltage DC power equipment, short circuit will result in equipment burning and endanger human safety.

Check carefully the polarity of the cable and connection terminal when performing DC live operations.

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

Insulated tools must be used.

Battery

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

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 pose potential threat to the equipment, it 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:

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

Use special insulated tools.

Wear an eye protection device, and take preventive measures.

Wear rubber gloves and apron to guard against electrolyte overflow.

In battery transportation, the electrode of the battery should always be kept facing upward. Never put the battery upside down or slanted.
