After completing the wiring of the power shelf perform the following:

Procedure 2 - Verification

Step

Action

1Verify that the power shelf has been mechanically secured.

2Verify that all the wiring performed is correct by using a voltmeter.

3Verify that all connections are mechanically correct (that is, tight, correct connector, correct marking etc.)

4Reinstall the AC and DC junction box cover on the left and right sides.

Installing the rectifier

The NT5C06D rectifier is a plug-in unit intended for use in the MPS75 power shelf.

Procedure 3 - Rectifier installation procedure

Step

Action

1

Release the clamping bar by loosening the two captive screws

2

Remove the blank panel for the rectifier to be installed (place a finger in the

 

hole, lift up, pull forward, then lower to disengage upper tabs from the shelf

 

top). Store the panel at the bottom of the shelf, under the rectifier.

3

Ensure that both AC and DC circuit breakers are in the OFF position.

4

Use a voltmeter to verify that the AC supply at the input of the shelf is 208

 

/ 240 V AC nominal.

5

Carefully slide the rectifier in position on top of the stored blank panel.

6

Insure that the rectifier is firmly slid and seated into position.

7

Reinstall the clamping bar by securing the two captive screws.
