Chapter 1 Basics and Assembly Manual VIPA System 200V1-2 HB97E - CPU - RE_21x-2BS03 - Rev. 15/16Safety Information for UsersVIPA modules make use of highly integrated components in MOS-Technology. These components are extremely sensitive to over-voltagesthat can occur during electrostatic discharges.The following symbol is attached to modules that can be destroyed byelectrostatic discharges.The Symbol is located on the module, the module rack or on packingmaterial and it indicates the presence of electrostatic sensitive equipment.It is possible that electrostatic sensitive equipment is destroyed by energiesand voltages that are far less than the human threshold of perception.These voltages can occur where persons do not discharge themselvesbefore handling electrostatic sensitive modules and they can damagecomponents thereby, causing the module to become inoperable orunusable.Modules that have been damaged by electrostatic discharges can fail aftera temperature change, mechanical shock or changes in the electrical load.Only the consequent implementation of protection devices and meticulousattention to the applicable rules and regulations for handling the respectiveequipment can prevent failures of electrostatic sensitive modules.Modules must be shipped in the original packing material.When you are conducting measurements on electrostatic sensitive modulesyou should take the following precautions:• Floating instruments must be discharged before use.• Instruments must be grounded.Modifying electrostatic sensitive modules you should only use solderingirons with grounded tips.Attention!Personnel and instruments should be grounded when working onelectrostatic sensitive modules.Handling ofelectrostaticsensitive modulesShipping ofelectrostaticsensitive modulesMeasurements andalterations onelectrostaticsensitive modules
