EMC Suitable Wiring
EMC (electromagnetic compatability) is defined as the ability of an
electric device to work error-free in a specific electromagnetic
surrounding, without being influenced by its surroundings and also
without influencing its surroundings in an inappropriate manner.
All Moeller products completely fulfil these high EMC requirements.
However, before the actual installation is carried out, an EMC plan
should be carried out, including all potential error sources.
Potential Error Sources
There are several ways how electromagnetic disturbances in
automated devices can occur. Depending on the type of source
(line-bound or line-unbound) and the distance between the error
source and the automated device, disturbances can appear in the
system in various ways.
Coupling Mechanisms
Galvanic Coupling:
Generally, a galvanic coupling occurs if two supply circuits use a
common line.
Typical sources are, e.g., starting motors, static discharges, clocking
devices and a potential difference between component housings
and the common power supply.
Inductive Coupling:
An inductive (magnetic) coupling occurs between two power-
supplying conductors. The current’s magnetic effect induces an
interference voltage. Typical sources are, e.g., transformers,
motors, parallel network cables and HF-signal cables.
Capacitive Coupling:
A capacitive (electric) coupling occurs between conductors which
have different potentials. Typical sources are, e.g., parallel signal
cables, contactors and static discharges.
