2.4.4 EMC-Conforming Assembly and Construction
2.4.4.1 General Principles
General Consid- Electric and electronical devices have to work correctly on site. This is also valid when electro-
erations magnetic influences affect them in defined and/or expected strength. The devices themselves
must not emit electro-magnetic noises.
Advant Controller components have a very high noise immunity.
When the wiring and earthing instructions are met, an error-free operation is given.
High electro-magnetic noises of nearby mounted applications must be taken in consideration
during the planning phase.
An EMC compatible earthing concept will also guarantee an error-free operation here.
