5.2.1 Wiring Notes
Generally, shielded cables are recommended for supply and interface (see section 9.2
"Accessories").
A proper and complete shielding concept is required for interference-free function.
Especially the conncetion of the cable shield on the both sides on the switching cabinet
and DME5000 must be ensured. The cable shield of the ready-made M16 cables is
connected to the metal plug and thus the DME5000 housing. The cable shield at the
switching cabinet must be connected to the operating ground with a large cross-section.
Potential balancing currents through the cable shield must be prevented by suitable
measures. Interference-free data transmission is only given when using shielded cables
with twisted-pair wires
The PROFIBUS cable shields are connected to each other via the PROFIBUS plugs.
Key cable groups figures 11 to 13:
1 = Highly interference-resistant cables (analog measuring cables)
2 = Interference-sensitive cables (sensor cable, communications signals, bus cables)
3 = Cables that are sources of interference (control cables for inductive loads, motor
brakes)
4 = Cables that are strong sources of interference (frequency converter output cables,
supply to welding plants; power cables)
groups 1, 2 and 3, 4
Ideal: Place cables in
Alternatively: Separate cables
