Replacement Procedures
Boardstack
(continued)
Boardstack Installation
To install the boardstack assembly:
1. Turn the device so that the power connector is visible, and lower the
boardstack assembly into its track. The boardstack assembly will not seat in
the tracks correctly if the therapy wires do not slide into the notch cut for
them in the boardstack assembly.
2. Place the A14 Inductive Resistor in the inductive resistor bracket (141).
3. Install the inductive resistor bracket (141) onto the PCB support bracket
(139) using two new 4-40
0.312 screws (173); torque to 6.8 in-lb. The
bottom bracket screw goes through the top hole of the EMI shield (274).
4. Connect the A14 Inductive Resistor’s cable to the A04 Therapy PCB at J1.
Route the cable under the W01 Therapy Cable as shown on the next page.
5. Tie wrap (229) the W07 Capacitor Discharge Cable to the inductive resistor
bracket (141).
6. Connect the A13 Energy Capacitor’s cable to the A04 Therapy PCB at J2.
7. Route the W07 Capacitor Discharge Cable with the A14 Inductive Resistor’s
cable as shown on the following pages.
