Electrical Safety

Electrical Safety

This topic describes safety notice about high voltage, thunderstorm, high electrical leakage, power cable, fuse, electrostatic discharge.

High Voltage

  • The high voltage power supply provides power for the device operation. Direct or indirect contact (through damp objects) with high voltage and AC mains supply may result in fatal danger.

  • Non-standard and improper high voltage operations may result in fire and electric shock.


Do not perform any operation, including high voltage and AC operations, on a steel tower or mast during a thunderstorm.

High Electrical Leakage

Ground the device before powering it on. Otherwise, personal injury or device damage may be caused by high leakage current.

If a "high electrical leakage" tag is present on the power terminal of the device, you must ground the device before powering it on.

Power Cable

Do not install or remove power cables when the device is on. Transient contact between the core of the power cable and the conductor may generate electric arcs or sparks, which may cause fire or hurt human eyes.

  • Before installing or removing the power cable, turn off the power switch.
  • Before connecting a power cable, check that the label on the power cable is correct.


If a fuse is to be replaced, the new fuse must be of the same type and specifications.

Electrostatic Discharge

The static electricity generated by human bodies may damage the electrostatic-sensitive components on boards, for example, the large-scale integrated (LSI) circuits.

Human body movement, friction between human bodies and clothes, friction between shoes and floors, or handling of plastic articles causes static electromagnetic fields on human bodies. These static electromagnetic fields cannot be eliminated until the static is discharged.

To prevent electrostatic-sensitive components from being damaged by the static on human bodies, you must wear a well-grounded ESD wrist strap when touching the device or handling boards or application-specific integrated circuits (ASICs).

Figure 1-1 shows how to wear an ESD wrist strap.
