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 motor and control cables are selected as specified in the hardware manual.
4. The drive 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 drive is used on such a network.
UL marking
cULus Listing is pending for the drive modules.

UL checklist
•
The drive module is to be used in a heated, indoor controlled environment. The drive
module must be installed in clean air according to enclosure classification. Cooling air
must be clean, free from corrosive materials and electrically conductive dust. See
page
132 .
•
The maximum ambient air temperature is 40 °C (104 °F) at rated current. The current
is derated for 40 to 50 °C (104 to 122 °F).
•
The drive module is suitable for use in a circuit capable of delivering not more than
100,000 rms symmetrical amperes, 600 V maximum when the input cable is protected
with class T fuses. The ampere rating is based on tests done according to UL 508C.
•
The cables located within the motor circuit must be rated for at least 75 °C (167 °F) in
UL-compliant installations.
•
The input cable must be protected with fuses. Circuit breakers must not be used
without fuses in the USA. For suitable circuit breakers, contact your local ABB
representative. Suitable IEC (class aR) fuses for drive protection are listed on page
125 and UL fuses on page 125 .
•
For installation in the United States, branch circuit protection must be provided in
accordance with the National Electrical Code (NEC) and any applicable local codes.
To fulfill this requirement, use the UL classified fuses.
