The drive type designation label includes the cULus listed marking. See Type designation
label on page 35.
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 must be used in a heated, indoor controlled environment. The drive must be
installed in clean air according to the enclosure classification. Cooling air must be clean,
free from corrosive materials and electrically conductive dust.
The maximum surrounding 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, 500 V (or 240 V) maximum when protected by the UL fuses given
in the table on page118. The ampere rating is based on tests done according to the
appropriate UL standard.
The cables located within the motor circuit must be rated for at least 75 °C (167 °F) in UL-
compliant installations.
Integral solid state short circuit protection does not provide branch circuit protection. The
input cable must be protected with fuses. See IEC fuses and UL classified fuses listed on
page 118. These fuses provide branch circuit protection in accordance with the National
Electrical Code (NEC) and Canadian Electrical Code.
For installation in the United States, also obey any other additional local codes.
For installation in Canada, also obey any additional provincial codes.
Note: For installation in the United states, do not use circuit breakers without fuses. For
suitable circuit breakers, contact your local ABB representative.
The drive provides motor overload protection. For the adjustments, see the Firmware
manual.
For drive overvoltage category and pollution degree, see data on page 129.
