QUICK-START InSTRUCTIOnS Important – You must read these simplified instructions before proceeding. These instructions are to be used as a reference only and are not intended to replace the details provided herein. You must read the Safety Warning on, pages 8 and 9, before proceeding. See Figure 1 on page 5. Also see Section 4 – Important Application Information, on page 20. WARnInG! Disconnect main power before making connections to the drive. 1.1 AC Line Connection – Wire the AC line input as described below and as shown in Figure 16 on page 31. See Section 9.1, on page 30. Application...

Ground Connection – Connect the ground wire (earth) to the ground screw, as shown in Figure 16, on page 31. See Section 9.2, on page 31. Note: Model KBVF-21D, due to its double insulated design, does not contain a ground screw. AC Line fusing – It is recommended that a fuse(s) or circuit breaker be installed in the AC line. Fuse each conductor that is not at ground potential. For the recommended fuse size, see Table 1, on page 14. Also see Section 10, on page 35. Motor Connection – Wire the motor to quick-connect Terminals “U”, “V”, “W”, as shown in Figure 16, on page 31. (Special reactors...

Voltage following – An isolated* 0 – 5 Volt DC analog signal input can be used to control motor speed in lieu of the Main Speed Potentiometer. The drive output will linearly follow the analog signal input. Connect the signal input positive lead (+) to Terminal “P2” and the negative lead (–) to Terminal “P1”. See Section 9.5, on page 32. *If a non-isolated signal is used, install the SIVFR — Signal Isolator (Part No. 9597). The SIVFR accepts voltage (0 to ±2.5 thru 0 to ±25 Volts DC) or current (4 – 20 mA DC) signal inputs. See Section 3.5, on page 13. Note: For signal following operation,...

This product should be installed and serviced by a qualified technician, electrician, or electrical maintenance person familiar with its operation and the hazards involved. Proper installation, which includes electrical connections, mounting and adequate enclosure, fusing or other current protection, and grounding can reduce the chance of electrical shocks, and/or fires in this product or products used with this product, such as electric motors, switches, coils, solenoids, and/or relays. Do not use this drive in an explosion-proof application. Eye protection must be worn and insulated...
