  • Page 11: General Safety Considerations

    General Safety Considerations Safety Earth Ground The instrument includes a grounded cord set containing a molded three-terminal polarized plug and a standard IEC320 (Type C13) connector for making line voltage and safety ground connection. The AC inlet ground terminal is connected directly to the frame of the instrument. For adequate protection against electrical shock hazard, the power cord plug must be inserted into a mating AC outlet containing a safety ground contact.

  • Page 12: Servicing

    Servicing These servicing instructions are for use by qualified personnel only。 To avoid electrical shock, do not perform any servicing unless you are qualified to do so。 Electrostatic Discharge Protection Protection against electrostatic discharge (ESD) is essential while removing assemblies from or connecting cables to the network analyzer。 Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged。Static discharges too small to be felt can cause permanent damage.

  • Page 13: General Information

    2. General Information Maintenance To prevent electrical shock, disconnect the analyzer from the mains source before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally。Clean the cabinet, including the front panel, using a dry or slightly damp cloth only.
