This document introduces the EMC design specifications for Moeller PS4 and PS416 PLCs
This document provides engineering guidelines to ensure interference-free operation of automation systems based on the Moeller PS 4 and PS 416 series. It details requirements for creating a uniform reference potential through low-impedance connections between inactive metal structures, such as control cabinets, mounting plates, and top-hat rails.
The manual covers specific construction rules for reference potential surfaces, including the proper installation of screened cables, incoming external screen cables, and inter-building wiring systems. It also addresses electrostatic discharge (ESD) measures, lightning protection strategies, and lists accessories designed to maintain interference-free design standards.
| Applicable Models | PS 4, PS 416 |
|---|---|
| Minimum Separation Distance | 10 cm |
A uniform reference potential must be created using conductively interconnected inactive metal structures.
They should be kept spatially separated, with a minimum distance of at least 10 cm between them.
A large-area, low-impedance conductive connection must be ensured between all inactive metal structures.
