Shielding Guidelines (continued)
If the drive continues to pick up noise after grounding the shield, it may
be necessary to add AC line filtering devices, or to mount the drive in a
less noisy environment.
Logic wires from other input devices, such as motion controllers and PLL
velocity controllers, must be separated from power lines in the same
manner as the logic I/O on this drive.
Line Fusing
ACE drives should be fused for protection. Use fast acting fuses rated for
250 VAC or higher and 150% of maximum armature current. Fuse HOT
L1 only when the line voltage is 115 VAC. Fuse both L1 and L2 when the
line voltage is 230 VAC. Table 1 on page 10 lists the recommended line
fuse sizes.
