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. See the
hardware manual.
• The maximum surrounding air temperature is +55 °C (131 °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, 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.
• The input cable must be protected with fuses. The fuses must provide branch
circuit protection in accordance with the national regulations (National Electrical
Code (NEC) or Canadian Electrical Code). Obey also any other applicable local
or provincial codes.
• Note: Circuit breakers must not be used without fuses in the USA. Contact your
local representative 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.
• The drive provides motor overload protection. For adjustments, see the firmware
manual.
• For the drive overvoltage category and pollution degree, see the hardware
manual.
