1. Remove power from the controller.
2. Pre-assemble the circuit board spacers onto the
Relay/High Voltage Output circuit board.
• Insert the pointed end of a circuit board spacer
into one of the four mounting holes of the
Relay/High Voltage Output circuit board from
the side of the circuit board that has the output
terminal blocks.
• Using firm pressure, seat the circuit board spac-
er’s “head” onto the surface of the Relay/High
Voltage Output circuit board.
• Repeat with the remaining three circuit board
spacers.
3. Pre-assemble the board stacking header onto the
Relay/High Voltage Output circuit board.
• Align the pins of the board stacking header to
the socket on the Relay/High Voltage Output
circuit board. Make sure all pins are aligned
properly.
• Using firm pressure insert the board stacking
header into the socket.
• Make sure all pins of the board stacking header
are seated properly.
4. Install the Relay/High Voltage Output circuit board.
• Align the pins of the board stacking header to
the socket on the main circuit board. Make sure
all pins are aligned properly.
• Align the pointed end of the four circuit board
spacers with the four mounting holes on the
main circuit board.
• While maintaining alignment of the pins of the
board stacking header and the circuit board
spacers, firmly press the Relay/High Voltage
Output circuit board onto the main circuit
board.
•Verify that all pins of the board stacking header
and the circuit board spacers are seated proper-
ly.
5. Verify Output Wiring.
• Install wiring to the appropriate output termi-
nals.
6. Test the Controller.
• Reapply power to the controller and test.
