UL checklist

• 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 the enclosure classification. Cooling air must
be clean, free from corrosive materials and electrically conductive dust.
• The maximum ambient air temperature is 50 °C (122 °F) at rated current. Except
for the R0 frame size, the current is derated for 50 to 60 °C (122 to 140 °F).
• The drive is suitable for use in a circuit capable of delivering not more than
100,000 rms symmetrical amperes, 480 V (or 240 V) maximum when protected
by the UL fuses given in the table on page 95. 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. Suitable IEC fuses are
listed on page 93
circuit protection in accordance with the National Electrical Code (NEC) and
Canadian Electrical Code. For installation in the United States, also obey any
other applicable local codes. For installation in Canada, also obey any applicable
provincial codes.
Note: Circuit breakers must not be used without fuses in the USA. Contact your
local representative for suitable circuit breakers.
• The drive provides motor overload protection. For the adjustments, refer to the
firmware manual.
• For drive overvoltage category, refer to page 110. For pollution degree, see page
111.
