Installation Manual: PSS 3032
3-1
Overview
The PSS 3032 is designed to be installed within an electromagnetic
industrial environment. To ensure electromagnetic compatibility the
correct procedures must be carried out when installing the system.
A device is electromagnetically compatible if:
• It functions without error in a given electromagnetic environment.
• It does not adversely affect its own environment.
Electromagnetic interference reaches the system through:
• Radiated fields
• Power supply
• Earth cabling
• Bus
• Interfaces
• Input and output cables
The interference can be transferred from the source to the receiver
(interference sink) via the coupling routes.
Interference reaches the interference sink (e.g. PSS 3032) in various
ways:
• DC coupling
This occurs if the source and sink of interference have common cable
connections. The common cable presents complex resistances, inducing
potential differences. Possible sources of interference are switches/
relays, running motors or varying potentials for other systems on the
same power supply.
