[. . . ] To remove the cover, gently press at the three push-ins until the cover disengages from the base. Models KBVF-22D, 13, 23, 23D, 14, 24, 24D, 26D ­ To remove the Finger-Safe Cover, gently lift up on the four retainer clips until the cover disengages from the base. Note: On Model KBVF-26D, the inner bus capacitor support bracket should not be removed. 5. 2 Installing the Finger-Safe Cover ­ To install the Finger-Safe Cover, be sure to properly align the retainer clips or push-ins. Gently push the Finger-Safe Cover onto the base until the retainer clips or push-ins are fully engaged with the base. 6 SETTING SELECTABLE JUMPERS The drive has customer selectable jumpers which must be set before the drive can be used. For the location of jumpers, see Figure 4, on page 20. 23 6. 1 AC Line Input Voltage Selection (Jumper J1 (Models KBVF-21D, 22D, 23D, 24D, 26D Only)) ­ Jumper J1 is factory set to the "230V" position for 208/230 Volt AC line input. For 115 Volt AC line input, set Jumper J1 to the "115V" position. See Figures 7 and 8. FIGURE 7 ­ MODELS KBVF-21D, 22D, 23D, 24D AC LINE INPUT VOLTAGE SELECTION 230 Volt AC Line Input (Factory Setting) (J1 Installed in "230V" Position) 115 Volt AC Line Input (J1 Installed in "115V" Position) 230V J1 115V J1 230V 115V For 115 Volt AC line input, on Model KBVF-26D, the jumper FIGURE 8 ­ MODEL KBVF-26D AC LINE INPUT VOLTAGE SELECTION must be removed and installed onto the 230 Volt AC Line Input "115VAC" position. Using (Factory Setting) 115 Volt AC Line Input (J1 Installed in "230VAC" Position) (J1 Installed in "115VAC" Position) pliers, gently rock the female terminal back and 230VAC 230VAC forth vertically while pulling it upward. See Figure 9, on page 25. J1 J1 115VAC For 115 Volt AC Line Input, remove this terminal and install it onto the "115VAC" position. Do not remove this terminal. 115VAC 24 6. 2 60Hz and 50 Hz Motor Operation and Drive Output Frequency Selection (Jumpers J1 and J2) ­ Both jumpers must be set for the appropriate motor nameplate frequency rating. 6. 2. 1 Setting the Drive for 60 Hz or 50 Hz Motor Operation ­ The drive is factory set to operate 60 Hz motors. 8. 1 Connect all equipment AC power input lines together and connect them to the H. V. Connect the RETURN of the Hi-Pot Tester to the frame on which the drive and other auxiliary equipment are mounted. 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 manually increased to the test voltage and then manually reduced to zero. Instantly applying the hi-pot voltage will cause irreversible damage to the drive, which will void the warranty. 28 8. 2 FIGURE 15 ­ TYPICAL HI-POT SETUP High Voltage Dielectric Withstand Tester (Hi-Pot Tester) 1 2 3 AC KILOVOLTS LEAKAGE 0 0mA 10mA RETURN TEST VOLTAGE H.

Also, do not bundle motor wires from multiple drives in the same conduit. Wire the drive in accordance with the National Electrical Code requirements and other local codes that may apply. Be sure to properly fuse each AC line conductor that is not at ground potential. [. . . ] Adjust the COMP Trimpot until the loaded RPM is equal to the unloaded RPM. The motor is now compensated to provide constant speed under varying loads. 13. 6 Boost (DEC/B) ­ When the drive is set for 50 Hz Motor Operation (Jumper J1 installed in the "50Hz" position), the DEC/B Trimpot automatically becomes the adjustable BOOST Trimpot. Most 60 Hz motors conforming to NEMA standards can operate from a preset Volts/Hz curve. [. . . ]
