Mounting Instructions
EMC cannot be ensured by the use of EMC filters alone. Every system should be considered as
an integrated whole and careful planning and preparation are required to ensure success.
Measures such as shielded motor cables, grounding and spatial separation are mandatory parts
of an integrated concept.
Plan your installation:
• Identify interference sources (with interference emissions) and disturbed equipment
(electrical equipment or components with limited interference immunity).
• Assign interference sources and disturbed equipment to specific zones and separate
them spatially from each other.
• Plan the cabling in wiring categories in accordance with interference emissions and
interference immunity.
EMC is an indispensable quality feature! The legally stipulated protection objectives and
technical risks must be taken into consideration as early as the development stage of the
system.
In order to achieve electromagnetic compatibility of the overall system the following points must
be observed:
1. The filter case should be connected across a large area to ground and to the other
equipment. For example, a blank metal mounting plate should be provided jointly for
filters and converters. It should be well grounded and connected to the switch cabinet via
a large-area low-inductance connection. If necessary, use short copper tapes and EMC
seals (e.g. connection to switch cabinet doors).
2. A distinction should be made between
a. The protective earth connection of the EMC filter, which is used to secure
protection against hazardous body currents, and
b. The large-area grounding of the filter, which is required for its interference
suppression function.
