Safety Information for Users
VIPA modules make use of highly integrated components in MOS-
Technology. These components are extremely sensitive to over-voltages
that can 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 electrostatic sensitive equipment.
It is possible that electrostatic sensitive equipment is destroyed by energies
and voltages that are far less than the human threshold of perception.
These voltages can occur where persons do not discharge themselves
before handling electrostatic sensitive modules and they can damage
components thereby, causing the module to become inoperable or
unusable.
Modules that have been damaged by electrostatic discharges can fail after
a temperature change, mechanical shock or changes in the electrical load.
Only the consequent implementation of protection devices and meticulous
attention to the applicable rules and regulations for handling the respective
equipment can prevent failures of electrostatic sensitive modules.
Modules must be shipped in the original packing material.
When you are conducting measurements on electrostatic sensitive modules
you should take the following precautions:
• Floating instruments must be discharged before use.
• Instruments must be grounded.
Modifying electrostatic sensitive modules you should only use soldering
irons with grounded tips.
Attention!
Personnel and instruments should be grounded when working on
electrostatic sensitive modules.
