UL checklist
WARNING!
Operation of this drive requires detailed installation and operation instructions
provided in the hardware and software manuals. The manuals are provided in
electronic format in the drive package or on the Internet. Keep the manuals with the
drive at all times. Hard copies of the manuals can be ordered through the
manufacturer.
• Make sure that the drive type designation label includes the applicable marking.
• DANGER - 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 surrounding air temperature is 45 °C at rated output current. The output
current is derated for 45…55 °C.
Note: For cabinet-built drives, the maximum surrounding air temperature is 40 °C
(104 °F).
• The drive is suitable for use in a circuit capable of delivering not more than 100 kA rms
symmetrical amperes, 600 V maximum when protected by the UL fuses given elsewhere
in this chapter.
• The cables located within the motor circuit must be rated for at least 75 °C in
UL-compliant installations.
• The input cable must be protected with fuses or circuit breakers. These protective
devices provide branch circuit protection in accordance with the national regulations
(National Electrical Code (NEC) or Canadian Electrical Code). Obey also any other
applicable local or provincial codes.
WARNING!
The opening of the branch-circuit protective device may be an indication that a
fault current has been interrupted. To reduce the risk of fire or electric shock,
current-carrying parts and other components of the device should be examined
and replaced if damaged.
• The drive is equipped with UL listed fuses which provide branch circuit protection in
accordance with the National Electrical Code (NEC) and Canadian Electrical Code.
The fuses are listed elsewhere in this chapter.
• The drive provides motor overload protection. The protection is not enabled when the
drive leaves the ABB factory. For enabling the protection, see the firmware manual.
• The drive overvoltage category according to IEC 60664-1 is III, except for auxiliary
power connections (fan, control, heating, lighting, cooling unit pump etc) which are of
category II.
