Electrical power network specification
ACS580-07-xxxxx-4 drives: 380…480 VAC 3-phase ±10%. This is indicated in the
type designation label as typical input voltage levels 3~400/480 V AC. Voltage (U

)
TN (grounded) and IT (ungrounded) systems Network type
Maximum allowable prospective short-circuit current is 65 kA when the input cable
is protected with gG type fuses (IEC 60269) having maximum operating time of
0.1 seconds and maximum current rating: Short-circuit withstand
strength (IEC 61439-1)
• 400 A for frames R6 to R8
• 630 A for frame R9
• 1000 A for R10
• 1250 A for R11
The drive is suitable for use on a circuit capable of delivering not more than 100,000
rms symmetrical amperes at 480 V maximum when the input cable is protected
with UL class T or L fuses. For selection of fuses for branch circuit protection, see
section
Fuses for branch circuit protection (page 178) . Fast acting class T and L or
faster are recommended in the USA. Obey local regulations.

motor cable length
Longer cables cause a motor voltage decrease which limits the available motor
power. The decrease depends on the motor cable length and characteristics. Note
that a sine filter (optional) at the drive output also causes a voltage decrease.
Contact ABB for more information.
Note:
With motor cables longer than 100 m (328 ft), the EMC Directive requirements
may not be fulfilled.
