Line fuses
Minarik drives require fuses for protection. Use fast acting
fuses rated for 250 VAC or higher, and approximately 150%
of the maximum armature current. Fuse only L1 when the line
voltage is 115 VAC. Fuse both L1 and L2 when the line
voltage is 230 VAC.
Table 2 lists the recommended line fuse sizes.
