[. . . ] Installation & Operation Manual KBVF SERIES Chassis / IP-20 AC Drives Variable Speed / Soft-Start AC Motor Drive with Electronic Motor Overload Protection* Rated for 208-230 and 400/460 Volt 50 & 60 Hz 3-Phase & PSC** AC Induction Motors from 2 thru 5 HP Operates from 208/230 Volt and 400/460 Volt 50/60 Hz AC Line Input*** CON3 J2 50/60Hz J1 X1 X2 CON1 This Manual Covers Models KBVF-27, 29, 45, 48 See Safety Warning, on page 8. **** Note: The drive is factory set for 60 Hz motors. For 50 Hz motors, see Section 6. 1, on page 14. The information contained in this manual is intended to be accurate. However, the manufacturer retains the right to make changes in design which may not be included herein. *UL approved as an electronic overload protector for motors. **Custom software is required for PSC motors. [. . . ] However, constant horsepower will result when operating the drive in the "X2" mode above the motor rated frequency. For 120 Hz output with 60 Hz motor, be sure Jumper J1 is set to the "60Hz" position and set Jumper J2 to the "X2" position. For 100 Hz output with 50 Hz motor, set Jumper J1 to the "50Hz" position and set Jumper J2 to the "X2" position. 6. 2 AUTOMATIC START (CON1) ­ The drive is factory set for Automatic Start (jumper installed onto CON1), as shown in Figure 11. The drive will automatically start when power is applied and a run command is given. The drive will automatically restart after a recovered fault due to undervoltage, overvoltage, or short circuit.

For Manual Start, a momentary contact must be installed onto CON1, as described in Section 9. 6, on page 20. 6. 3 FORWARD/REVERSE SPEED SELECTION ­ Models KBVF-27, 29 are factory set for Forward Speed Operation (jumper installed in the "F-S" position of CON2). For reverse Speed Operation, install the jumper in the "R-S" position. See Section 9. 7, on page 20.

Care should be taken to avoid extreme hazardous locations where physical damage to the drive can occur due to moisture, metal chips, dust, and other contamination, including corrosive atmosphere that may be harmful. To prevent accidental contact with high voltage, it is required that the Finger-Safe Cover be properly installed onto the drive after all wiring and setup is complete. Do not use this drive in an explosion proof application. 15 The enclosure should be large enough to allow for proper heat dissipation so that the ambient temperature does not exceed 45 °C (113 °F). Leave enough room to allow for AC line, motor connection, and other wiring that is required. When mounting the Main Speed Potentiometer, be sure to install the insulating disc between the potentiometer and the panel. When mounting these drives in a vertical direction, the cooling fan must be on top. When mounting the drive in an enclosure, be sure to leave at least 2" of clearance around the cooling fan for proper heat dissipation. 8 RECOMMENDED HIGH VOLTAGE DIELECTRIC WITHSTAND TESTING (HI-POT TESTING) Testing agencies such as UL, CSA, etc. , usually require that equipment undergo a hi-pot test. In order to prevent catastrophic damage to the drive, which has been installed in the equipment, the following procedure is recommended. [. . . ] Increase the boost until the ammeter reaches the nameplate rated current (Amps AC). Using the Main Speed Potentiometer, slowly adjust the motor speed over a 0 ­ 15 Hz (0 ­ 450 RPM) range. If the motor current exceeds the nameplate rating, decrease the boost setting.

The CL Trimpot is factory set to 160% of the drive rated current. [. . . ]
