Step 3: Remove the Pulse
Transformer and Switching
Power Supply Boards
Note: The Switching Power Supply circuit board is located on the back of
the Pulse Transformer circuit board. You must remove both boards in order
to replace the AC Current Transducers. Note: The Switching Power Supply
circuit board does NOT need to be removed from the Pulse Transformer
circuit board.
1. Remove the plug-in terminal from the field input block at the top of the
drive.
2. Remove the four screws that secure the slotted air flow plate to the top
of the drive chassis.
Important: The air flow plate is also secured to the Pulse Transformer
circuit board and therefore cannot yet be removed.
Instructions for doing so are included later in this
procedure.
