Part Replacement Procedures
This chapter describes procedures required to replace drive
components. This chapter references Chapter 3 – Disassembly and
Access Procedures for basic drive component access.
The part replacement procedures in this chapter assume that the drive
you are servicing either has no enclosure or that the enclosure is
open. For more information on opening the Drive Enclosure, refer to
Chapter 3 – Disassembly and Access Procedures, Opening the Drive
Enclosure.
!
ATTENTION: Some printed circuit boards and drive
components may contain hazardous voltage levels.
Remove power before you disconnect or reconnect
wires and before you remove or replace fuses and
circuit boards. Verify bus voltage by measuring the
voltage between +DC and –DC on terminal block TB1.
Do not attempt to service the drive until the bus voltage
has discharged to zero volts.
!
ATTENTION: This assembly contains parts and
sub-assemblies that are sensitive to electrostatic
discharge. Static control precautions are required when
servicing this assembly. Component damage may result
if you ignore electrostatic discharge control procedures.
If you are not familiar with static control procedures,
reference Rockwell Automation Publication
8000-4.5.2, Guarding Against Electrostatic Discharge,
or any other applicable ESD protection handbook.
