• 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 40 °C at rated output current. The
output current is derated for 40 … 55 °C.
• 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 drive is suitable for use in a circuit capable of delivering not more than 65 kA
rms symmetrical amperes, 480 V maximum when protected by the UL circuit breakers
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.
Suitable UL fuses are listed in section Fuses (UL) (page 210) and circuit breakers in
section Circuit breakers (UL) (page 216).
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 provides motor overload protection. This feature is not enabled when the
drives leaves the ABB factory. For enabling this motor overload protection, see the
firmware manual.
• The drive overvoltage category according to IEC 60664-1 is III.
• To maintain the environment integrity of the enclosure, replace the cable grommets
with field-installed industrial conduit hubs or closure plates required by the enclosure
type (or better).
Approvals
The drive is marine type approved. For more information, see ACS880-01/04 +C132
marine type-approved drives supplement (3AXD50000010521 [English]).
