A. AC Power – The KBSI-240D is powered with either 115
or 230V AC, 50/60 Hz by arranging the jumpers
between terminals “1” to “4” properly. See figures 2A
and 2B. Be sure unit is wired in accordance with the
National Electric Code and other codes that may apply.
It is recommended that a 1 amp fuse be installed in
series with the AC line.
B. Input Terminals – A voltage or current signal from a
microprocessor, tachometer, transducer, etc. is to be con-
nected to terminals “5” through “8.” The selection of the
proper terminal is based on the maximum level of the input signal. See figures 3 and 4.
