Cautions and Warnings Important Information Please read all safety and warning notes carefully before installing the EMC filter and putting it into operation (see ! ). The same applies to the warning signs on the filter. Please ensure that the signs are not removed nor their legibility impaired by external influences. Death, serious bodily injury and substantial material damage to equipment may occur if the appropriate safety measures are not carried out or the warnings in the text are not observed.
Important Notes The following applies to all products named in the publication: 1. Some parts of this publication contain statements about the sustainability of our products for certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned.
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).
For operating currents greater than 250 A, we recommend the PE connection to be set up between the feed (filter: line) and output (filter: load) not via the PE terminal bolt in the filter housing. This is because of the restricted area of the cable lug of the PE connection to the filter housing. Ideally, the PE feed line should be connected with the PE output line to a PE busbar which also carries the PE terminal(s) of the EMC filter.
4. Keep cables from the interference source as short as possible! Examples: • Short connection from the converter to the EMC filter; ideally a flange mounted filter to avoid emissions. • Connection cables of minimum length between converter output and motor (also to reduce asymmetrical currents caused by the parasitic capacitances of the cable shield). 5.
• • • Connection cables between frequency converter and motor, if no corresponding output filter is used. Connection cables filter and converter on the line side, where not directly flange mounted It should be noted that the shielding effect of different cables can differ widely (foil shield, braided shield with various degree of coverage, combinations). 6.
7. Arrange EMC filters as far as possible directly at the entry or exit points of the housing Examples: • Line terminals are accessible via the corresponding opening of the equipment (ensure protection against electric shock). • Use of suitable EMC filters. • Use of corresponding housing matching elements to ensure the required shielding attenuation 8.
9. In order to reduce interference coupling, as far as possible run the cables close to metal parts which are connected to the reference potential (mounting plates, switch cabinet etc.) Live cables should also be run as close as possible to the reference potential (to reduce inductively coupled interferences). In order to improve electromagnetic compatibility, cable channels, cable trays and installation tubes which are made of metal rather than plastic parts should be preferred. 10.
11. Connect suitable EMC components close to switched inductors (e.g. contactors, relays, magnetic valves etc.). 12. For control signals in the vicinity of high interference levels, use transmission techniques such as: • Differential-mode transmission systems with twisted-pair lines in conjunction with data line chokes. • Transmission of digital signals according to the RS-422 standard or in extreme cases crossing the interference region with fiber-optic cables. 13.
• • As the parasitic currents flow via the ground connection of the installation, the sum of the input currents into the filter is no longer equal to zero. A specific magnitude of the parasitic current can lead to a saturation of the common-mode choke in the EMC filter and consequently exceed the permissible interference level. The interference voltage should therefore be measured on the installed equipment.
