UL checklist
• 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 manual
MN1961WEN for detailed specifications.
• The maximum ambient air temperature is 45 °C (113 °F) at rated current. The
current is derated for 45 to 55 °C (113 to 131 °F). Fan cooling is required to allow
full rated current on the 6 A and 9 A models, as explained in this document.
• The drive is suitable for use in a circuit capable of delivering not more than 5,000
rms symmetrical amperes, 230 V maximum.
• 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 or circuit breakers. Suitable types
are listed in the complete product manual, MN1961WEN. 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.
• For installation in Canada, branch circuit protection must be provided in
accordance with Canadian Electrical Code and any applicable provincial codes.
To fulfill this requirement, use the UL classified fuses.
• The drive provides overload protection in accordance with the National Electrical
Code (NEC). Use the Mint WorkBench software to configure overload protection
settings.
