US and Canada: The drive is suitable for use on a circuit capable of
delivering not more than 100 kA symmetrical amperes (rms) at 480
V maximum when protected by fuses given in the fuse table. The
drive is also suitable for use on a circuit capable of delivering not
more than 65 kA symmetrical amperes (rms) at 480V maximum when
protected by the specific manual self-protected Type E combination
motor controllers given in the manual self-protected combination
motor controller table, provided the drive is mounted within an en-
closure of adequate minimum volume, and the assembly complies
with all applicable footnotes of the table. Short-circuit current

(UL 61800-5-1, CSA
C22.2 No. 274-13)
Use a mains choke if the network's line impedance is low (less than
0.3% total system impedance of all the ACS180 drives in the install-
ation), or has voltage imbalance, or harmonic distortion that make
the input current bigger than the nominal input current ratings. You
can use one choke for several drives as long as the choke current
rating is not exceeded. Mains choke
