8.2.6 Capacitor Banks
Upper Capacitor Banks
1. Remove the control assembly support bracket and the gate drive card in accordance with the instructions.
2. The capacitor bank connection to the DC bus bars can be seen recessed in the gap between the upper and the lower capacitor banks. A minimum
extension of 6 inches (150 mm) is required. Remove the 6 electrical connection nuts (8 mm) for the upper capacitor bank on the DC bus bars.
3. Remove the 4 retaining nuts (10 mm) from the capacitor bank and remove the air dam.
4. Note that the weight of the capacitor bank is approximately 20 pounds (9 kg). Remove the capacitor bank by pulling free from the mounting studs.
Reinstall in reverse order of this procedure. Tighten the electrical connection nuts (8 mm) to 2.3 Nm (20 in-lbs) and the mechanical connection nuts (10 mm) to 4
Nm (35 in-lbs).
Lower Capacitor Banks
1. Remove the soft charge card in accordance with procedures.
2. The capacitor bank connection to the DC bus bars can be seen recessed in the gap between the upper and the lower capacitor banks. A minimum
extension of 150 mm (6 in) is required. Remove the 6 electrical connection nuts (8 mm) for the lower capacitor bank from the DC bus bars.
3. Remove the 4 retaining nuts (10 mm) from the capacitor bank.
4. Note that the weight of the capacitor bank is approximately 9 kg (20 lbs). Remove the capacitor bank by pulling free from the mounting studs.
Reinstall in reverse order of this procedure. Note: DO NOT overtorque. Tighten the electrical connection nuts (8 mm) to 2.3 Nm (20 in-lbs) and the mechanical
connection nuts (10 mm) to 4 Nm (35 in-lbs).
