[. . . ] 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. Jumper J1 is located on the upper PC board. 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. Jumpers J1 and J2 are located on the lower PC board. 6. 2. 1 Setting the Drive for 60 Hz or 50 Hz Motor Operation ­ The drive is factory set to operate 60 Hz motors. Jumper J1 is factory set to the "60Hz" position and Jumper J2 is factory set to the "X1" position. When mounting the Main Speed Potentiometer, be sure to install the insulating disc between the potentiometer and the panel. 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. A typical hi-pot test setup is shown in Figure 15, on page 29. All drives have been factory hi-pot tested in accordance with UL requirements. All equipment AC line inputs must be disconnected from the AC power. 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. This procedure must be followed for each machine being tested. [. . . ] Run the motor unloaded at approximately 4 Hz (or 120 RPM). Note: An unloaded motor with excessive boost will draw more current than a partially loaded motor. 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. [. . . ]
