EMC information
A trouble-free operation of the measuring system devices of the company ELGO Electronic GmbH & Co KG
can only be guaranteed if during assembly, wiring and operating the following basic rules are observed and
adhered to:
•
Use only shielded signal lines with a minimum diameter of 0.15 mm²
•
To protect against electrical fields, connect the cable shield unilaterally, low resistance and
low inductive with the operating lightning protection.
•
Unused arteries in signal lines should be isolated from each other separately
•
Isolate signal and power lines in long parallel lines (a distance of 300 mm is required).
Therefore, should never different voltage levels be combined in one cable, e.g. 230V/50 Hz power
supply and measuring system signal 24V DC.
•
To reduce interference of frequency converters, the use of RC-filter, shielded cable and EMC
compliant grounding of frequency converter switchboards are recommended. Please find the
necessary instructions in the manufacturer operation manual of the frequency converter.
•
Wireless phones and Walky-talkies should never be used in the immediate vicinity of electronic
devices
