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 logic leads is not practical the user should twist all logic leads with themselves to minimize induced noise It may be necessary to earth ground the shielded cable If noise is produced by devices other than the drive ground the shield at the drive end If noise is generated by a device on the drive ground the shield at the end away from the drive Do not ground both ends of the shield 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 6 Installation Speed adjust potentiometer connections A Warning Be sure that the potentiometer tabs do not make contact with the potentiometer enclosure Grounding the input will cause damage to the drive Install the circular insulating disk between the mounting panel and the 10K ohm speed adjust potentiometer see Figure 2 Mount the speed adjust potentiometer through a 0 38 inch 10 mm hole with the hardware provided Twist the speed adjust potentiometer wires to avoid picking up unwanted electrical noise MOUNT THROUGH A 0 38 IN 10 MM HOLE MU SPEED ADJUST POTENTIOMETER INSULATING PANEL DISK POT TAB ASSIGNMENTS Figure 2 Speed Adjust Potentiometer
