EMC Notes Electromagnetic Compatibility
As all electrical equipment, synchronous generators with integral electronics can emit electromagnetic energy and
be influenced by it.
Electromagnetic compatibility requires on the one hand that equipment is insusceptible to interference as regards
electromagnetic radiation, i.e. that they cannot be influenced, and on the other hand does not exceed a certain
level of interference radiation, and as a consequence does not interfere with other equipment.
These levels depend on the environment in which the equipment is operated. Here a distinction is made between
industrial and residential environments including business and commercial as well as light-industrial environments.
This chapter is to serve as a guideline for installation of the drives to avoid EMC problems and realize an EMC-
compliant wiring in accordance with the EMC Directive.
3.3.1 Interference Immunity
CG4 ... are extremely susceptible to interference as regards electromagnetic radiation.
Interference immunity is achieved for the equipment without additional aids. In addition, all induction components,
such as relay and contactor coils, electromagnetic brakes, etc. are to be interference-suppressed using suitable
components (e.g. RC elements).
3.3.2 Interference Radiation
To avoid unallowable interference radiation it is absolutely necessary to observe the given wiring instructions.
Non-line-related interference radiation is directly emitted by the integrated electronics and wiring within a
frequency range of 30 MHz to 1 GHz. It is mainly generated by the fast logic circuits and has very low energy.
Problems with other electronic equipment due to this are not be expected.
Line-related interference radiation in the frequency range of 150 kHz to 30 MHz is mainly caused by switching of
the power semiconductors. Because of the independent network, no problems with other equipment will occur.
3.4
Magnet Connection
The electrical line connections and plug-in connection (plug / coupling) are matched to the corresponding output of
the power generators. In the process, the highest requirements are made on functionality and safety.
Please only use original MOZELT spare parts as required.
