4.5.3 Special requirements
Special considerations are required for the following requirements:
Meeting the residential emission standard, EN50081-1 (Size 1 only)
One of the footprint filters (part number 4200-6102 or 4200-6103) must be used.
Interruptions to the motor cable
The motor cable should ideally be a single run of shielded cable having no interruptions.
In some situations it may be necessary to interrupt the cable, for example to connect the
motor cable to a terminal block within the drive enclosure, or to fit an isolator switch to
allow safe working on the motor. In these cases both motor cable shield connections
must be clamped directly to the back-plate or other flat metallic structure, as illustrated
in figures 4.13 and 4.14. Keep the length of unscreened power conductors to a
minimum, keep them as close as possible to the metal plate, and ensure that all
sensitive equipment and circuits are at least 0.3m (12in) away from them.
Terminal block within enclosure
Refer to Figure 4.13.

Using a motor isolator switch
Refer to Figure 4.14.

4.5.4 RFI filter recommendations and data.
Use one RFI filter for each drive. Filters of appropriate current rating may be shared
between drives, but small deviations from the stated standards may then occur.
The filter performance depends upon the motor cable length and switching frequency.
The filter performance for the maximum motor cable length for residential and industrial
standards is shown in Table 4.4 to Table 4.13. For further details on filter performance
with shorter cable lengths, see the EMC Data sheets which are available from Control
Techniques’ Drive Centres or Distributors.
