Introduction: Safety Considerations
WARNING SYMBOLS AND TERMS
The following symbols and terms may be found on the equipment described in this manual.
This symbol on the unit indicates that the user should refer to the operating instructions located in the manual.
This symbol on the unit indicates that high voltage may be present. Use standard safety precautions to avoid
personal contact with this voltage.
This symbol indicates that the test fixture, Model 482C, must be connected to earth ground via the power cord.
The
WARNING
heading used in this manual explains dangers that might result in personal injury or death. Always
read the associated information very carefully before performing the indicated procedure.
The
Caution
heading used in this manual explains hazards that could damage the instrument.
WARNING 1: The power supply/signal conditioner should not be opened by anyone other than qualified service
personnel.
This product is intended for service by qualified personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid injury.
WARNING 2:
This equipment is designed with user safety in mind; however, the protection provided by the equipment
may be impaired if the equipment is used in a manner not specified by PCB Piezotronics, Inc.
Caution 1: Cables can kill your equipment.
High voltage Electro Static Discharge (ESD) can damage electrical
devices. Similar to a capacitor, a cable can hold a charge caused by triboelectric transfer, such as that which occurs in
the following:
Laying on and moving across a rug.
Any movement through air.
The action of rolling out a cable.
Contact to a non-grounded person
The solution for product safety: 1) Connect the cables only with the AC power off. 2) Temporarily “short” the end of
the cable before attaching it to any signal input or output.
Caution 2: ESD considerations should be made prior to performing any internal adjustments on the equipment.
Any
piece of electronic equipment is vulnerable to ESD when opened for adjustments. Internal adjustments should therefore
be done ONLY at an ESD-safe work area. Many products have ESD protection, but the level of protection may be
exceeded by extremely high voltage that is typically present in normal situations.
