Ground Filter Component Replacement
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 failed capacitor/resistor bank.
4. Loosen and remove mounting screws as indicated in Figure 5.33 and
remove the failed component.
5. Assemble the new component in the reverse order of disassembly.
6. Reattach the leads strictly adhering to the torque requirements
outlined below.
I M P O R T A N T I M P O R T A N T The maximum torque for the capacitor terminal
is 3.4 Nm (30 lb-in).
