7 AC LINE INPUT VOLTAGE SELECTION (JUMPER J1)
Do not connect the AC line input until Jumper J1 is set for the proper input voltage being
applied to the drive. Catastrophic failure will occur if a 230 Volt AC line is applied when the drive is set
for 115 Volt AC line input.
The drive is factory set for 208/230 Volt AC line input (Jumper J1 not installed). For 115 Volt AC line input,
install Jumper J1 (supplied). See Figure 10.

Notes: 1. The drive is factory set for 208/230 Volt AC line input (Jumper J1 not installed). For 115
Volt AC line input, install Jumper J1 (supplied). 2. Jumper J1 is supplied in the hardware bag.
8 RECOMMENDED HIGH VOLTAGE DIELECTRIC WITHSTAND TESTING (HI-POT TESTING)
Testing agencies such as UL, CSA, VDE, 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 11, on page 15. All drives have been factory hi-
pot tested in accordance with UL requirements.
WARNING! All equipment AC line inputs must be disconnected from the AC power.
CAUTION! Model KBMK-24DF: To prevent catastrophic damage to the drive, perform a DC Hi-Pot test only.
8.1
Connect all equipment AC power input lines together and connect them to the H.V. lead of the hi-pot
tester. Connect the RETURN lead of the hi-pot tester to the frame on which the drive and other auxiliary
equipment are mounted.
8.2
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 to be tested. A suggested hi-pot tester is Slaughter Model 2550.
CAUTION! Instantly applying the hi-pot voltage will cause irreversible damage to the drive, which will
void the warranty.
