Safety information for users
VIPA modules make use of highly integrated components in MOS-
technology. These components are extremely sensitive to over-voltages
that may occur during electrostatic discharges.
The following symbol is attached to modules that can be destroyed by
electrostatic discharges:
The symbol is located on the module, the module rack or on packing
material and it indicates the presence of electrostatically sensitive
equipment.
It is possible that electrostatically sensitive equipment is destroyed by
energies and voltages that are far less than the human threshold of
perception. These voltages may occur where persons do not discharge
themselves before handling electrostatically sensitive modules and they
may damage components thereby causing the module to become
inoperable or unusable. Modules that have been damaged by electrostatic
discharge are usually not detected immediately. The respective failure may
become apparent after a period of operation.
Components damaged by electrostatic discharges can fail after a
temperature change, mechanical shock or changes in the electrical load.
Only the consistent implementation of protective devices and meticulous
attention to the applicable rules and regulations for handling the respective
equipment is able to prevent failures of electrostatically sensitive modules.
Please ship the modules exclusively in the original packing material.
When you are conducting measurements on electrostatically sensitive
modules you should take the following precautions:
•
Floating instruments must be discharged before use.
•
Instruments must be grounded.
You should only use soldering irons with grounded tips when you are
making modifications on electrostatically sensitive modules.
Attention!
Personnel and instruments should be grounded when working on
electrostatically sensitive modules.
