Additional Instructions to Comply with EN61800-3,
Second Environment
Always use optional RFI filter as specified in Table 11 and follow the
instructions in the filter package for all cable screen connections.
The motor cable lengths have to be limited as specified in Table 11. At the
motor end, the cable screen must be earthed 360 degrees with an EMC
cable gland (e.g. Zemrex SCG screened cable glands).
Table 11 Maximum motor cable lengths with input filter ACS100/140-IFAB-1,
-IFCD-1, or ACS140-IFAB-3, -IFCD-3 and switching frequency 4 kHz, 8 kHz
or 16 kHz.
Distribution Networks Isolated from Earth
Input filters cannot be used in floating supply networks, or high impedance
earthed industrial distribution networks.
Make sure that no excessive emission is propagated to neighbouring low
voltage networks. In some cases, the natural suppression in transformers
and cables is sufficient. If in doubt, a supply transformer with static screening
between the primary and secondary windings can be used.
