Rockwell Automation GV3000/SE, VTAC 7 Super Remote Meter Interface Board M/N 2SI3000 M/N 2SI3000E - Manual (Page 46)

3-32 Super Remote Meter Interface (RMI) Board
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.
Important: Read and understand the warning labels on the inside of the drive before
proceeding.
Step 2. Verify That the DC Bus Capacitors are Discharged
Step 2.1 Open the drive’s outer cabinet door.
Step 2.2 Lower the plastic terminal strip shield at the top of the drive.
Step 2.3 Use a voltmeter to verify that there is no voltage at the drive’s AC input
power terminals, R, S, and T.
Step 2.4 Replace the plastic terminal strip shield.
Step 2.5 Ensure that the DC bus capacitors are discharged. To check
DC bus potential:
a. Stand on a non-conductive surface and wear insulated gloves. (600 V)
b. Use a voltmeter to check the DC bus potential at the Voltmeter Test
Points on the Power Module Interface board. See figure 3.16.
Step 3. Remove the Keypad Bracket from the Drive
Refer to figure 3.16 for component locations.
