5 Installation
Line fuse
The M1740009.00 drive is protected by a 5A, 250V AC line
fuse. The fuse does not have to be resized as long as the
motor used is within the drive’s specified horsepower range.
The fuse is mounted in the fuseholder (see Figure 2). To
replace a blown fuse, use a screwdriver to turn the
fuseholder knob counterclockwise. Remove the blown fuse
and replace with a new fuse.
