Electrostatic Discharge
Semi-conductors of the type MOS or CMOS as well as two-pin types and precision resistance are
sensitive to ESD. All components, printed circuit boards and auxiliary systems should therefore always
be classed as sensitive to electrostatic discharge.
Before opening the cover the unit should be placed onto an ESD-protected surface. As with all work on
modern electronic modules the use of ESD clamps and ESD mats during work on the unit is
recommended.
• Sufficiently protect all printed circuit boards that were removed from the unit from damage.
• Observe all normal precautions for the use of tools.
• Use ESD-protected packaging material.
Never use measuring units with low impedance for measuring or testing systems with semi-conductor
components. Never use high voltage testing units or dielectric test units to test systems with semi-
conductor components.
If it is necessary to check the isolating properties of the field wiring, the assemblies (electronic units
and sensors) should be disconnected.

precautions and protective packaging materials were not followed.
