Mounted on top of the cabinet is an air exhaust hood. The exhaust hood must be
installed to prevent foreign objects from entering the drive.
Output Grounding Network Replacement
PowerFlex 7000 drives may have either a grounding network or a ground filter in
place of the grounding network.
The number of capacitors will vary depending on the system voltage.
1. Ensure there is no power to the equipment.
Note the position of the leads.
2. Remove the 6.4 mm (¼ inch) hardware and disconnect the leads
connected to the terminals.
3. Four brackets are used to secure the capacitor. Loosen the four screws at
the base of the brackets and lift the capacitor out.
4. Place the new capacitor and tighten the screws securely.
5. Replace the ring lugs and 6.4 mm (¼ inch) hardware ( Figure 82 ).

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 N•m (30 lb•in.).

Important: Torque on
capacitor terminals must
be 3,4 N•m (30 lb•in)
