UL checklist
• Use the drive 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.
• 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. The ampere rating is based
on tests done according to UL 508C.
• 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. Circuit breakers must not be used
without fuses in the USA. Suitable IEC (class aR) fuses and UL (class T) fuses
are listed in the hardware manual. For suitable circuit breakers, contact your local
ABB representative.
• For installation in the United States, branch circuit protection must be provided in
accordance with the National Electrical Code (NEC) and any applicable local
codes. To fulfill this requirement, use the UL classified fuses.
