Moeller DF6-340 Series - EMC Measures in the Control Panel

01/02 AWB8230-1413GB
EMC compliance
23
At leakage currents f 3.5 mA, VDE 0160 and EN 60335, one of
the following conditions must be fulfilled:
• the protective conductor has a cross-section f 10 mm
2
,
• the protective conductor is monitored to ensure continuity, or
• an additional protective conductor is installed.
For DF6 frequency inverters, use the assigned DE6-LZ... filters.
EMC measures in the control panel
To ensure an EMC-compliant setup, connect all metallic
components of the devices and of the control cabinet with each
other using a large cross-section conductor with good HF
conducting properties. Do not make connections to painted
surfaces (Eloxal, yellow-passivized). If there is no alternative, use
contact and scraper washers to ensure contact with the base
metal. Connect mounting plates to each other, and the cabinet
doors with the cabinet, using contacts with large surface areas and
short HF wires.
The figure below provides an overview of all EMC measures.
