ABB ACS480-04-09A8-1, Hardware Manual

Page: 172 / 240

• The drive is suitable for use in a circuit capable of delivering not more than 100000 rms
symmetrical amperes, 480 V maximum (480 V drive types) or 240 V maximum (240 V
drive types) 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 drive is suitable for use on a circuit capable of delivering not more than 65000 rms
symmetrical amperes, 480Y/277 V maximum (480 V drive types), when protected by
a Type E combination motor controller specified by ABB.
• 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 UL-rated fuses, or the ABB Type E manual
motor protectors (MMP) listed in this manual. The fuses or the manual motor protectors
provide branch circuit protection in accordance with the National Electrical Code (NEC)
and 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 integral solid state short circuit protection of the drive does not provide branch
circuit protection.
• The drive provides motor overload protection. For adjustments, see the firmware
manual.
