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 section
Ambient conditions
• The maximum ambient air temperature is 40 °C (104 °F) at rated current. The
current is derated for 40 to 50 °C (104 to 122 °F).
• The drive is suitable for use on a circuit capable of delivering not more than 65 kA
rms symmetrical amperes at the drive nominal voltage (600 V maximum for 690 V
units) when protected by T class fuses.
• 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 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 fulfil this requirement, use the UL classified fuses.
• For installation in Canada, branch circuit protection must be provided in
accordance with the Canadian Electrical Code and any applicable provincial
codes. To fulfil this requirement, use the UL classified fuses.
• The drive provides overload protection in accordance with the National Electrical
Code (NEC). See ACS800 Firmware Manual for setting. Default setting is off,
must be activated at start-up.
