Remove the DPI Interface Assembly
To remove the DPI interface assembly, follow these steps.
1. Remove power from the AFE.
See Remove Power from the AFE
on page 37.
2. For an AFE in an IP20 2500 MCC Style enclosure, disregard this step.
For an AFE in an IP21 Rittal enclosure, locate the control assembly
(item 6 in Figure 5 on page 23
), and remove the two screws from the
front of the DPI hinged assembly.
3. For an AFE in an IP20 2500 MCC Style enclosure, open the control box
door to access the DPI interface board.
For an AFE in an IP21 Rittal enclosure, open the hinged assembly that
holds the DPI interface board.
4. Unplug the DPI cable from the X2 connector on the DPI interface
board.
5. Remove the four screws and the assembly from the control frame.
IMPORTANT Before you remove the connections and wires, mark them to avoid
incorrect wiring during assembly.
