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 checklist
WARNING! Operation of this drive requires detailed installation and operation
instructions provided in the hardware and firmware manuals. The manuals can be
found on the Internet. Depending on the product series, the drive package may
contain the manuals in electric format or as hard copies (as standard or ordered with
option codes with the drive). Hard copies of the manuals can also be ordered through the
manufacturer separately. Retain the hard copies of the manuals with the drive.
•
Make sure that the drive type designation label includes the cULus Listed marking.
•
CAUTION - Risk of electric shock . After disconnecting the input power, always wait
for 5 minutes to let the intermediate circuit capacitors discharge before you start
working on the drive, motor or motor cable.
•
The drive is to be used in a heated, indoor controlled environment. The drive 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
196 .
•
The maximum ambient air temperature is 40 °C (104 °F) at rated current. The current
is derated for 40 to 55 °C (104 to 131 °F).
•
The drive is suitable for use in a circuit capable of delivering not more than 100,000
rms symmetrical amperes, 600 V maximum, when protected with fuses listed on page
191. The ampere rating is based on tests done according to UL 61800-5-1.
•
The cables located within the motor circuit must be rated for at least 75 °C (167 °F) in
UL-compliant installations.
