Manual MVK-MP
V 3.5 11
The high voltages that occur when inductive loads are shut down result in strong fields in the cables
with consequential faults in adYescent circuits or devices. Therefore we recommend for large distances
between module output and load or for possible other reasons, an additional suppression of the
inductive load. This causes the voltage spike generated by the inductive load to be short-circuited at the
source.
Murrelektronik offers a wide selection of interference suppression components.

2.2.7 Other Measures and Limits
In some system configurations, the requirements for interference emission and immunity from
interference can only be met with additional measures, or even not at all. In these cases, the EMC
within the system is also dependent on the signle components of other manufacturers.
Mains filters are a suitable means of reducing line-conducted interference.
Various manufacturers offer optical-fiber converters. This data transmission technology
is basically immune to EMC interferences. However, this does not apply to the
electronic conversion circuits. For this reason, the use of optical fibers does not solve all
EMC problems.
Our certified test center will answer your questions regarding EMC. They will give
advice on guaranteeing compliance with the EMC directive for the system you
produce.
