Compliance; Category C1; Category C2; Category C3 - ABB ACS150 series User Manual

Category C2 has the same EMC emission limits as the earlier class first environment restricted
distribution. EMC standard IEC/EN 61800-3 does not any more restrict the distribution of the drive, but
the using, installation and commissioning are defined.
Drive of category C3: drive of rated voltage less than 1000 V, intended for use in the second
environment and not intended for use in the first environment.
Category C3 has the same EMC emission limits as the earlier class second environment unrestricted
distribution.

Compliance

Category C1

The emission limits are complied with the following provisions:
1. The optional EMC filter is selected according to the ABB documentation and installed as specified in
the EMC filter manual.
2. The motor and control cables are selected as specified in this manual.
3. The drive is installed according to the instructions given in this manual.
4. For the maximum motor cable length with 4 kHz switching frequency, see section
data on page 144.
WARNING! In a domestic environment, this product may cause radio inference, in which case
supplementary mitigation measures may be required.

Category C2

The emission limits are complied with the following provisions:
1. The optional EMC filter is selected according to the ABB documentation and installed as specified in
the EMC filter manual.
2. The motor and control cables are selected as specified in this manual.
3. The drive is installed according to the instructions given in this manual.
4. For the maximum motor cable length with 4 kHz switching frequency, see section
data on page 144.
WARNING! In a domestic environment, this product may cause radio inference, in which case
supplementary mitigation measures may be required.

Category C3

The immunity performance of the drive complies with the demands of IEC/EN 61800-3, second
environment (see page
The emission limits are complied with the following provisions
1. The internal EMC filter is connected (the screw at EMC is in place) or the optional EMC filter is
installed.
2. The motor and control cables are selected as specified in this manual.
3. The drive is installed according to the instructions given in this manual.
4. With the internal EMC filter: motor cable length 30 m (100 ft) with 4 kHz switching frequency.
For the maximum motor cable length with an optional external EMC filter, see section
connection data
WARNING! A drive of category C3 is not intended to be used on a low-voltage public network which
supplies domestic premises. Radio frequency interference is expected if the drive is used on such a
network.
Note: It is not allowed to install a drive with the internal EMC filter connected on IT (ungrounded)
systems. The supply network becomes connected to ground potential through the EMC filter capacitors
which may cause danger or damage the drive.
