Electromagnetic Protect your equipment from interference by observing the rules
and recommendations specified in the Technical Manual.
compatibility
Intended place of This unit fulfills the requirements for EN 50370-1 and is intended
operation for operation in industrially zoned areas.
Likely sources of Interference is produced by capacitive and inductive coupling into
interference electrical conductors or into device connections, caused by e. g .:
•
Strong magnetic fields from transformers or electric motors
•
Relays, contactors and solenoid valves
•
High-frequency equipment, pulse equipment and stray magnetic
fields from switch-mode power supplies
•
Power lines and leads to the above equipment
•
Protective mea- Keep a minimum distance of 20 cm from the MC, CC and its
sures leads to devices that carry interference signals
•
Keep a minimum distance of 10 cm from the MC, CC and its
leads to cables that carry interference signals. For cables in
metallic ducting, adequate decoupling can be achieved by using
a grounded separation shield.
•
Shielding according to EN 50 178
•
Use equipotential bonding conductors with a cross section of
6 mm
•
Use only genuine HEIDENHAIN cables and connecting
elements
