(Buss type ABC, Littlefuse type 314, or equivalent). For more information on fusing please refer to the

KBPB operators manual.

4.4.4 KBPB Modification

If a KBPB-225 (designed for use at 220/240 VAC ) is used with 90 volt DC motors the KBPB-225 must be

modified to insure that DC voltages greater than 90 volts are not applied to the motor. The model KBPB-

225 is used in all interface boxes designed for 220/240 VAC operation. If the customer specifies that the

interface box will be used with 90 volt DC motors this modification will be performed when the interface

box is assembled. This information is presented here for the case where the KBPB is replaced in the field

Here is the modification: Place a jumper between the A+ and B terminals. These terminals are located on

the circuit board near the toroid type transformer. Access to this point is from the same side of the module

as where the connector labels are found. The A+ terminal is a .250” quick disconnect type. The B

terminal is a .110” quick disconnect type. You can accomplish the same results on late model KBPB-225s

by simply placing a J2 jumper in the ‘90’ position. A late model KBPB incorporates surface mount printed

circuit board technology. Earlier model KBPB units employ thru-hole printed circuit board technology.
