Chapter 1 Safety Description Safety Symbols Meaning Laser: Beware of strong laser beam. Scald: Beware of scald. Amongst these safety symbols, the universal alarm symbols are classified into three levels: danger, warning, and caution. The formats and meanings of the three levels are described as below: Danger: Indicates a potentially hazardous situation which, if not avoided, will result in death or serious injury of people, or equipment damages and breakdown.
ZXSDR RSUC User Manual Danger: High voltage is hazardous. Direct or indirect contact with high voltage or main supply using a wet object could result in death. � � � � � Strictly follow local safety rules to install AC power devices. Installation staff must be qualified for performing high-voltage and AC operations. Do not wear any watch, hand chain, bracelet, ring or any other conductive objects during such operations.
Chapter 1 Safety Description Thunderstorms would give rise to a strong electromagnetic field in the atmosphere. Therefore, the equipment must be grounded and protected in time against lightning strikes. Antistatic Safety Instructions Electrostatic: Static electricity produced by human body can damage static-sensitive components on circuit board, such as large-scale integrated circuits. � Friction caused by human body activities is the root cause of electrostatic charge accumulation.
