Tips and Tricks
9.1. Improving the EMC safety
9.1.1. Introduction
The wireless data systems DATAEAGLE are electronic
devices which are built according to the latest state of
technology. The ruggedly mechanical structure as well as the
construction of the electronic components is designed for
industrial applications.
Nevertheless some measurements have to be taken during
installation, which are important for an error free operation. If
these are not observed, the measurements which have been
taken within the devices for achieving a higher interference
resistance and surge immunity will become partly inefficient.
The interference resistance of the complete system depends
highly on the correct installation, place of installation and
wiring. Before installation, always check which installation
instructions are required by the supplier of the controller for a
safe operation. These instructions should be consistent with
the recommendations given here.
9.1.2. Basic guidelines
Noise voltages which are injected by supply and signal lines
into the device as well as electrostatic voltages caused by
contact will be discharged to the grounding point. The
grounding point has to be connected with a preferably short
copper cable (with little resistance) to the protective earth
conductor connection of the device.
