  • Page 16: Important Application Information

    IMPORTANT APPLICATION INFORMATION MOTOR WITH EXTERNAL FAN COOLING – Most totally enclosed fan-cooled (TEFC) and open ventilated 3-phase AC induction motors will overheat if used beyond a limited speed range at full torque. Therefore, it is necessary to reduce motor load as speed is decreased. Note: Some fan-cooled motors can be used over a wider speed range.

  • Page 17: Mounting Instructions

    To maintain the watertight integrity of the drive, be sure to use suitable liquidtight fittings and wires that are appropriate for the application. Model KBDA-24D contains mounting holes for standard 1/2” liquidtight fittings (not supplied) (two liquidtight plugs are provided, if only one knockout is used).

  • Page 18: Drive Terminal Block Wire And Tightening Torque Specifications

    Note: The rated AC line voltage of the drive must match the actual AC line input voltage. On Models KBDA-24D, 27D, the setting of Jumper J1 must match the AC line input voltage. AC Line Fusing – The drive does not contain line fuses. Most electrical codes require that each ungrounded conductor contain circuit protection.

    The hi-pot tester must have an automatic ramp-up to the test voltage and an automatic ramp-down to zero voltage. Note: If the hi-pot tester does not have automatic ramping, then the hi-pot output must be manu- ally increased to the test voltage and then manually reduced to zero. This procedure must be fol- lowed for each machine to be tested.
