Table 9 Maximum motor cable lengths with input filter ACS100-FLT-C or
ACS140-FLT-C and switching frequency 4 kHz or 8 kHz.
*
Effective motor cable screen is required, according to .
**ACS143-4K1-1: maximum continuous load 70 % of nominal.
For ACS141-4K1-1 and ACS143-4K1-1, a cable shown in Figure 21 is required.
If input filter ACS100-FLT-C or ACS140-FLT-C is used with 200 V units,
always use output choke ACS-CHK-B when motor cable length exceeds 50
m. Also with 200 V units use output choke ACS-CHK-A with filters ACS100-
FLT-C and ACS140-FLT-C.
If input filterACS140-FLT-C is used with 400 V units, always use output
choke ACS-CHK-B when motor cable length is 30...50 m and three output
chokes SACL22 if motor cable length exceeds 50 m.
Chokes ACS-CHK-A and ACS-CHK-B are supplied in the same package
with the input filter ACS100-FLT-C and ACS140-FLT-C.
With input filters ACS100-FLT-C or ACS140-FLT-C conducted emission
complies with the limits for unrestricted distribution class in First
Environment as specified in EN 61800-3 (EN 50081-1) provided that the
motor cable has effective screen (see Figure 21) and maximum length is
30 m.
Additional Instructions to Comply with EN61800-3,
First Environment, Unrestricted Distribution
Always use optional RFI filter ACS100-FLT-D, ACS100-FLT-E or ACS140-
FLT-D 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 10 and the
cable must have effective screen according to Figure 21. At the motor end,
the cable screen must be earthed 360 degrees with an EMC cable gland
(e.g. Zemrex SCG screened cable glands).
