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.
