A gray background indicates wire sizes that are larger than the maximum wire rating of the drive's terminal blocks.
External junction box required to splice cable sizes.
NOTE: 460VAC models with output motor cable lengths exceeding 1,000 feet require an additional load reactor or sine
filter to be installed between the drive output and the motor. The load reactor or sine filter should be rated for 3% voltage
drop in 460VAC applications and have a maximum amp rating suitable for the maximum output amp rating of the drive.
