Measures for EMC assurane 6.8T
• The smallest possible effective aerial height is reached, if you install the cable directly on the surface of
grounded car riers.
Figure 6.5: Cable laying for minimum aerial height
• All cables should basically be laid as near as possible to the conductors of the chassis ground system, in
order to reduce the loop area which is effective for magnetic decoupling.
Figure 6.6: Cable laying for minimum loop area
• At parallel laying of signal or control cables compared with power cables you must comply with a mini-
mum clearance of 20cm between the conductors.
• The clearance between cables with especially high interference potential and cables on the mainsside
of the mains filter must be at least 30cm.
• Cross cables of different EMC categories only in a 90° angle.
• At symmetrical signal transmission (e.g. differential amplifier inputs for the speed setpoint) you must
link the conductors of each core pair together, and then link the core pairs one with another.
