UL/CSA markings

The ACS800-01 and ACS800-U1 units of UL type 1 are cULus listed and CSA
marked.

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 100
kA rms symmetrical amperes at the drive nominal voltage (600 V maximum for
690 V units) when protected by fuses given in the NEMA data fuse table. 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 this 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 the firmware manual for setting. Default setting is off, must be
activated at start-up.
• Brake chopper - ABB has brake choppers that, when applied with appropriately
sized brake resistors, will allow the drive to dissipate regenerative energy
(normally associated with quickly decelerating a motor). Proper application of the
brake chopper is defined in chapter
