STEP 12 - CONNECT THE WIRING

For the chassis ground connection:
1. Loosen the screw terminal with a flathead screwdriver.
2. Insert the ground wire into the ground lug, beneath the screw.
3. Tighten the screw terminal with a flathead screwdriver.
For the high voltage connection:
1. Pull both locking tabs on the spring terminal away from the board and toward the wall.
2. Insert the Positive High Voltage wire into the left slot marked "+", all the way to the bottom.
Close the locking tab by pushing it up and away from the wall, so that the tab is flush with the
connector.
3. Insert the Negative High Voltage wire into the right slot marked "-", all the way to the bottom.
Close the locking tab by pushing it up and away from the wall, so that the tab is flush with the
connector.
4. Lightly tug on each wire to ensure it is seated properly.
5. If any wire must be removed, pull the locking tab open, then pull out the wire.
Warning: Verify that both High Voltage tabs are locked completely shut over the wires (the
image shows the correct position). The tabs have an intermediate position that shuts halfway,
which is NOT electrically safe.
For the J7 Communication Port:
1. Insert the wire for the Enable line into the leftmost port labeled "ENABLE".
2. Insert the wire for Logic Power (Power) into the second port labeled "LOGIC+".
3. Insert the wire for Logic Power (Return) into the third port labeled "LOGIC-".
4. Insert the wire for Negative Communication to the fourth port labeled "COM LO".
5. Insert the wire for Positive Communication to the fifth port labeled "COM HI".
6. Lightly tug on each wire to ensure it is seated properly.
7. If any wire must be removed, push down on the appropriate button, then pull the wire out.
Note: A small screwdriver might be needed to push the release down far enough.
For thermal power:
1. Insert the wire for Thermal Power (Return) into the port labeled "THERMAL -".
2. Insert the wire for Thermal Power (Power) into the port labeled "THERMAL +".
3. Lightly tug on each wire to ensure it is seated properly.
4. If any wire must be removed, push down on the appropriate button, then pull the wire out.
Note: A small screwdriver might be needed to push the release down far enough.
