4.5 EMC-compliant cabinet design
The most cost-effective method of implementing interference suppression measures within
the control cabinet is to ensure that interference sources and potentially susceptible
equipment are installed separately from each other.
The control cabinet has to be divided into EMC zones and the devices within the control
cabinet have to be assigned to these zones following the rules below.
● The different zones must be electromagnetically decoupled by using separate metallic
housings or grounded separation plates.
● If necessary, filters and/or coupling modules should be used at the interfaces of the
zones.
● Cables connecting different zones must be separated and must not be routed within the
same cable harness or cable channel.
● All communication (e.g. RS485) and signal cables leaving the cabinet must be shielded.
