6 PNEG-1587 KBIC SCR Control Kit Installation
2. Installation
Replacing the Woods Board
1. Disconnect the power to the circuit.
2. For ease of re-connection, record the colors and terminal numbers of all wires leading to the Woods
board. Disconnect wiring and remove board. Mount the KBIC board in approximately the same
location, oriented as shown in
Figure 1A on Page 5 . Note that additional holes must be drilled into
the mounting surface using a 9/64" drill bit. Try to keep power terminal L1 and L2 in approximately
the same location as before to help prevent the need for longer wire lengths.
3. Mount the DIN Rail (D03-0013-BRK) next to the KBIC board if possible using a 9/64" drill bit. Use
the self tapping screws to secure the DIN Rail to the panel. Snap the SCR contactor (D03-0106)
onto the DIN Rail.
4. Reconnect the wires as follows:
5. Strip the end of the supplied black 16 gauge wire and connect it to the wire between the L1 terminal
of the SCR contactor and the L1 terminal of the KBIC board. Now strip and connect a wire to the
L3 terminal of the SCR contactor and the L2 terminal of the KBIC board.
6. Connect the supplied white 18 gauge wire to the A2 terminal of the SCR contactor. Connect the
other end to any available AC neutral connection. This is usually a white wire labeled with a
number 2 at its connection point.
7. Connect the wire (See Figure 2A on Page 7) that was connected to terminal 7 on the Woods board
to the A1 terminal of the SCR contactor. If additional wire length is required, use part of the supplied
yellow 18 gauge wire and wire nut (HH-1462).
8. Connect the wire that was connected to terminal 6 to the supplied yellow 18 gauge wire using the
supplied wire nut (HH-1462) and the other end to a fused 110 VAC power source. You can use any
connection that wire number 3 or number 27 is connected to.
