• 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 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 176) and circuit breakers in
section Circuit breakers (UL) (page 177).
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
drive 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).
Declarations of conformity
See the chapter The Safe torque off function (page 209).
Design lifetime expectancy
The design lifetime expectancy of the drive and its overall components exceeds ten (10)
years in normal operating environments. In some cases, the drive can last 20 years or
more. To achieve a long lifetime of the product the manufacturer’s instructions for sizing
the drive, installation, operational conditions and preventive maintenance schedule shall
be followed.
