warning 1
–
ESD sensitivity
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
–
ESD sensitivity
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.

–
ESD sensitivity
Cables can kill your equipment.
High voltage electrostatic 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, and/or
Contact with a non-grounded person.
The PCB solution for product safety:
Connect the cables only with the AC power off.
Temporarily

the end of the cable before attaching it to any signal input or output.
caution 2
–
ESD sensitivity
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.
