8 Tips and tricks
8.1 Improvement of EMC resistance
8.1.1 Introduction
Industrial use
The device is manufactured and developed according to the latest state of the
art. Both the robust mechanical construction and the design of the electronic
components are designed for industrial use.
To ensure trouble-free operation, rules must be observed when installing
the devices in systems. If these are not observed, the high interference and
destruction resistance of the devices will be partially ineffective.
The immunity of the entire system depends largely on correct installation,
location and wiring.
• Check the controller manufacturer’s assembly instructions for safe
operation.
• Bring these into line with the recommendations for EMC-compliant design.
• Then install the device
8.1.2 Basic rules
PE connection (protective earth)
Interference voltages coupled into the device via the supply and signal lines,
as well as electrostatic voltages transmitted by touch, are discharged to the
grounding point.
→ Connect the grounding point to the PE-connector of the device with low
impedance using the shortest possible copper conductor.
Shielding
Shielded lines reduce the probability of interference :
• by a factor of 100 compared to unshielded cables
• by a factor of 1000 if looping is also avoided.
The density of the braided shield should be at least 85%. To prevent the
interference currents coupled onto the cable shield from becoming interference
sources themselves, a low-impedance connection to the grounding point is
particularly important.
→ Always use shielded cables for interfaces and power supplies.
→ Use shielding braid with a density of at least 85 %.
→
Always connect the shield on both sides to the EMC ground (usually PE).
