Additional Instructions to Comply with EN61800-3, First Environment, Restricted
Distribution, and AS/NZS 2064, 1997, Class A
Always use an optional RFI filter as specified in Table 29 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 29 and the cable must have
effective screen according to Figure 68. 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 29 Maximum motor cable lengths with input filters ACS400-IF11-3... ACS400-IF41-3 and
switching frequency 4 kHz or 8 kHz .

Conducted emission with input filters ACS400-IF11-3 and ACS400-IF21-3 complies with the limits
for unrestricted distribution class in First Environment as specified in EN61800-3 (EN50081-1)
provided that maximum motor cable length is 30 m and switching frequency 4 kHz.
Line Current Harmonics
The current harmonic levels under rated load conditions are available on request.
Distribution Networks Isolated from Earth
Input filters designed for ACS 400 cannot be used in an isolated, or high impedance earthed
industrial distribution networks.
