Heat sinking

C1MMXL and C4MMXL series drives contain sufficient heat
sinking in their basic configurations. There is no need for
additional heat sinking.

Line fusing

Minarik drives require fuses for protection. Cased MMXL drives
are prewired with two internal 15A fuses. Use fast acting fuses
rated for 250 VAC or higher and approximately 150% of the
maximum armature current.

Table 1 lists the recommended line fuse sizes.
