The number of capacitors will vary depending on the system voltage.
1. Ensure there is no power to the equipment.
A T T E N T I O N A T T E N T I O N To prevent electrical shock, ensure the main power
has been disconnected before working on the
capacitor. Verify that all circuits are voltage free
using a hot stick or appropriate voltage-measuring
device. Failure to do so may result in injury or
death.
2. Note the position of the leads.
3. Disconnect the leads connected to the capacitor/resistor bank.
4. Loosen and remove mounting screws as indicated in Figure 6.11
and remove the component.
5. Assemble the new component in the reverse order of
disassembly.
6. Reattach the leads strictly adhering to the torque requirements
outlined in Figure 6.8)
