Introduction: Safety Considerations
WARNING 1:
The power supply/signal conditioner should not be opened by anyone other than qualified service
personnel.
This product is intended for use 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 electrostatic discharge 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 with 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.
