UL and CSA 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.
• For UL and CSA compliant installations, 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.
