Chapter 5 Preventative Maintenance and Component Replacement

Inspect the bus bars and cable connections. Check for any signs of overheating /

discoloration and tighten the bus connections to the required torque

specifications. Clean all cables and bus bars that exhibit dust build-up. Check for

corrosion, excessive temperature, or contamination.

Inspect Power Module Input and Output Power Connections

Verify that all Power Module input line cables and output bus connections are

properly torqued. Verify the output cables, VSB Cables and star connection

cables are properly torqued. Apply torque sealer if required. Check for corrosion,

excessive temperature, or contamination.

General

Review Firmware and Hardware

Verify the firmware version on the HMI. Contact Rockwell Automation to

determine whether there are any enhancements or changes made to the Drive

Hardware and Control that would be valuable to the application.

Verify that the HMI is operational. Check the status indicators on the Control

Unit in the LV Control Cabinet register as normal.

Remove any dirt or foreign material. Wipe components with an anti-static cloth,

where applicable.

Inspect/Review Spare Parts

Check for signs of damage, dirt, or foreign material. See Spare Parts on page 127.

ATTENTION: Ensure there is no power to the drive and wear an anti-static

wristband.

ATTENTION: Some circuit boards can be destroyed by static charges. Use of

damaged circuit boards may also damage related components. Use a grounding

wrist strap when handling sensitive circuit boards.
