EMC-compliant setup

5.2.1

Introduction

The electronic weighing system described here was developed for use in industrial
environments and complies with high EMC requirements. Nevertheless, you should still carry
out EMC planning before installing your devices in order to determine any sources of
interference and include them in your considerations.
EMC
EMC (electromagnetic compatibility) describes the capability of electrical equipment to
operate without errors in a given electromagnetic environment, without being subject to
external influence and without influencing external devices in any way.
5.2.2

Possible effects of interference

Electromagnetic interferences can influence the electronic weighing system described here
in various ways:
● Electromagnetic fields having a direct influence on the system
● Interferences transported by communication cables
● Interferences having an effect via process cables
● Interferences entering the system via the power supply and/or protective ground
Interferences can impair the fault-free functioning of the electronic weighing system.
