UL checklist
WARNING! Operation of this drive requires detailed installation and operation
instructions provided in the hardware and software manuals. The manuals are
provided in electric format in the drive package or on the Internet. Retain the manuals
with the drive at all times. Hard copies of the manuals can be ordered through the
manufacturer.
• 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. UL Type 12
(IP55) enclosure provides protection from airborne dust and light sprays or
splashing water from all directions. See the hardware manual.
• The maximum surrounding air temperature is 50 °C (122 °F) at rated current. The
current is derated for 40 to 50 °C (104 to 122 °F).
• The drive is suitable for use in a circuit capable of delivering not more than
100,000 rms symmetrical amperes, 480 V maximum when protected by the UL
fuses on page 12. 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. For UL Type 12 drives of frame R6, the
power cables must be rated for 90 °C (194 °F) minimum. For ambient
temperatures above +40 °C (+104 °F), the power cables must be rated for 90 °C
(194 °F) minimum.
• Integral solid state short circuit protection does not provide branch circuit
protection. The input cable must be protected with fuses. Suitable UL (class T)
fuses are listed on page 12. These fuses provide branch circuit protection in
accordance with the National Electrical Code (NEC) and Canadian Electrical
Code. For installation in the United States, obey any other applicable local codes.
For installation in Canada, obey any applicable provincial codes.
• Note: Circuit breakers must not be used without fuses in the USA. Consult ABB
for suitable circuit breakers.
WARNING! The opening of the branch-circuit protective device may be an
indication that a fault current has been interrupted. To reduce the risk of fire
or electric shock, current-carrying parts and other components of the device
should be examined and replaced if damaged.
