Protective measures against discharge of static electricity
• Disconnect the power supply before you install or remove modules which are sensitive to
ESD.
• Pay attention to good grounding:
When handling electrostatical sensitive devices, make sure that persons, the workstation
and devices, tools and packaging used are properly grounded. This way you avoid static
discharge.
• Avoid direct contact:
– As a general rule, do not touch electrostatic sensitive devices, except in the case of
unavoidable maintenance work.
– Hold the modules at their edge so that you do not touch the connector pins or
conductor paths. This way, the discharge energy does not reach and damage the
sensitive components.
– Discharge your body electrostatically by touching grounded metallic parts before you
take a measurement at a module. Always use grounded measuring instruments.
