• 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…50 °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, 480 V maximum when protected by the UL
fuses given elsewhere in this chapter. The ampere rating is based on tests
done according to the appropriate UL standard.
• 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. For adjustments, 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).
