Page 27: Wiring
Installation Wiring Warning DO NOT install, rewire, or remove this control with input power applied. Failure to heed this warning may result in fire, explosion, or serious injury. Circuit potentials are at 115 or 230 VAC above ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements. -
Page 28: Shielding Guidelines
As a general rule, Minarik recommends shielding of all conductors. If it is not practical to shield power conductors, Minarik recommends shielding all logic-level leads. If shielding the logic leads is not practical, the user should twist all logic leads with themselves to minimize induced noise. -
Page 29: Heat Sinking
Installation 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. -
Page 30: Fusing
Installation Fusing VFD series drives require external AC power line fuses. Connect the external line fuse(s) in series with the AC voltage input. See Connections on page 22. Use fast- acting fuses rated for 250 VAC or higher. See Table 1 for recommended line fuse sizes. -
