NOTICE
Grounding measures
There is no equipotential bonding without grounding. An electrostatic charge is not
discharged and may damage the ESD.
Protect yourself against discharge of static electricity. When working with electrostatic
sensitive devices, make sure that the person and the workplace are properly grounded.
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 before you take a measurement at a module. Do
so by touching grounded metallic parts. Always use grounded measuring instruments.
7.2.2
Electromagnetic compatibility
Pulse-shaped interference
The Industrial Flat Panels have been tested for high-energy single pulse (surge) in
accordance with IEC 61000-4-5.
An external protective circuit is required for operation with 24 VDC; please refer to the
chapter "Lightning and Surge Voltage Protection" in the "S7-300 Automation System,
Hardware and Installation" installation manual. The "S7-300 Automation System, Hardware
and Installation" installation manual is available for download from the Internet

The following lightning protection element was used during the testing of the
Industrial Flat Panel:
Dehn BVT AVD 24" (Order No. 918 422)
