Step 4: Remove the

Existing Pulse Transformer

Board

1. Disconnect the (red and white) gate leads from connectors XP1 and XP2 at

the top-left corner of the board.

2. Disconnect the appropriate gate leads from the pulse transformer board (see

Figure 3

below):

– For non-regenerative drives, each pair of (red and white) gate lead cables

from connectors KG1…KG6.

– For regenerative drives, each pair of (red and white) gate lead cables from

connectors KG1…KG6 and KG01…KG06.

3. Disconnect the cables from the following connectors: XUV, XCD_IO,

XUVW, XCD, XR, XTA, X4 and XSPF. Also, carefully remove the ribbon

cable (from XR) from the cable standoff on the board.
