with one line fuse in fuse holder FU501. Models MM03-230AC-PCM and

Preinstalled line fuses are rated for maximum horsepower. If the
horsepower rating of the motor being used is less than the maximum
horsepower rating of the drive, the line fuse may have to be replaced
with a lower rated one. Fuses should be rated for 250 VAC or higher and
approximately 150% of the maximum armature current. Refer to Table 1
to install a lower rated fuse.
