Rockwell Automation GV3000/SE V.6 Regulator Board 0-56921-6xx, 413338-6BU, 0-56940-6xx, 814.61.00 - Manual (Page 67)

10-2 GV3000/SE Drive Version 6 Regulator Board Installation Instructions
This procedure requires access to the right side of the drive. Remove the drive from
the panel if necessary.
Unless otherwise indicated, keep all hardware that is removed. You will need it for
reassembly. This includes screws, lock washers, and rivets.
Important: Read and understand the warning labels on the outside of the drive
before proceeding.
Step 1. Shut Down the Drive
Step 1.1. Disconnect, lock out, and tag all incoming power to the drive.
Step 1.2. Wait five minutes for the DC bus capacitors to discharge.
Step 1.3. Record the wiring to the Regulator board terminal strip.
Step 1.4. Drives with option boards only: Record the wiring connections to the option
board terminals.
Step 1.5. Disconnect all wiring from the face of the drive.
Step 1.6 2 to 15 A drives: Remove the cover by removing the cover screw on the
faceplate of the drive. See figure 10.1.
24 to 30 A drives: Remove the cover by removing the cover screw on the
faceplate of the drive. Then remove the front panel by removing the two
screws on the faceplate of the drive. See figure 10.2.
Step 1.7. Disconnect the cover from the Regulator board by using a screwdriver to
slide the cable out of the connector.
Step 2. Verify That the DC Bus Capacitors are Discharged
Step 2.1. Use a voltmeter to verify that there is no voltage at the drive’s AC input
power terminals (L1, L2, L3). Refer to figure 10.1 or 10.3 for the location of
these terminals.
Step 2.2. Ensure that the DC bus capacitors are discharged. To check
DC bus potential:
a. Stand on a non-conductive surface and wear insulated gloves.
b. Use a voltmeter to measure the DC bus potential at the DC bus power
terminals ((–)45, (+)47)) shown in figure 10.1 or 10.3.
Step 2.3 24 to 30 amp drives: Reattach the front panel after checking the DC bus
potential.
