3. Maximum cable length is 100 metres.
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.

Category C4
If the provisions under Category C3 cannot be met, the requirements of the standard can
be met as follows:
1. It is ensured 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, the supply transformer with static screening between the primary
and secondary windings can be used.
2. An EMC plan for preventing disturbances is drawn up for the installation. A template is
available from the local ABB representative.
3. The generator and control cables are selected as specified in the Hardware Manual .
4. The converter is installed according to the instructions given in the Hardware Manual .
WARNING! A drive of category C4 is not intended to be used on a low-voltage public
network which supplies domestic premises. Radio frequency interference is expected if
the converter is used on such a network.
UL marking
The converter is cULus listed industrial control panel. The approvals are valid with rated
voltages up to 600 V AC. The markings are attached to the converter when C129
(cULus) is selected. ETL marking according to UL508C up to 690 V AC is pending.
Contact the local ABB representative when ETL marking is required.
ACS800 multidrive modules: The module is cULus listed industrial control equipment. The
approvals are valid with rated voltages up to 600 V.

UL checklist
Input power connection – Short-circuit current protection (UL 508A): The converter is
suitable for use in a circuit capable of delivering not more than 65,000 symmetrical
amperes (rms) at 600 V maximum when protected with the fuses given in section
Fuses .
Disconnecting device (disconnecting means) – See chapter Planning the electrical
installation .
