• 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 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 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 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
