Explanations on the EMC safe installation of a drive system:
11. If filters are fitted then the following points are to be observed: In general the
leakage current increases through the use of filter elements. If this exceeds a
limiting value of 3.5 mA then one of the following conditions must be fulfilled:
• PE cross-section at least 10 mm²
• Monitoring of the protective conductor by an appliance, which leads to an
automatic switching off in the case of a defect.
• Routing of a second cable, electric parallel to the PE via separate terminals.
This must itself fulfil the requirements according to VDE 0100 Part 540 (e g
minimum cross-section).
12. In order to achieve as low a load as possible of the supply net in general line
chokes with a short circuit voltage of 4% are used. The line choke is to be
placed between mains connection and radio interference suppression filter.
