2 Basics
2.1 Safety information for users
The modules make use of highly integrated components in MOS-Technology. These com-
ponents are extremely sensitive to over-voltages that can occur during electrostatic dis-
charges. The following symbol is attached to modules that can be destroyed by electro-
static discharges.
The Symbol is located on the module, the module rack or on packing material and it indi-
cates 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 dis-
charge 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:
n Floating instruments must be discharged before use.
n
Instruments must be grounded.
Modifying electrostatic sensitive modules you should only use soldering irons with
grounded tips.
CAUTION!
Personnel and instruments should be grounded when working on electro-
static sensitive modules.
