Ground Filter Replacement

The number of capacitors will vary depending on the system voltage.

1.

Ensure there is no power to the equipment.

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 232

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 229

)

Loosen screws to

release capacitors

Remove screws for

replacing resistor bank

Important !
Torque on capacitor terminals
3,4 Nm (30 lb-in) maximum

Important!
Torque on resistor bank assembly
1,2 Nm (11.0 lb-in) maximum

ATTENTION: 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.

IMPORTANT

The maximum torque for the capacitor terminal is 3.4 Nm (30 lb-in).
