Remove the DSP board
1. Disconnect the DSP connector (1) from the top of the DSP board (3).
Note: This step is only required on systems that have an RS485 communication board installed.
Systems without an RS485 communication board installed will not have a connector plugged
into the top of the DSP board.
2. Use a #2 Phillips screwdriver to remove the 2 screws (2) from the DSP board.
Two rows of connector pins (4) are located on the back of the DSP board (3) as shown in the figures below. The
dashed rectangle identifies the location of the pins on the back of the board.
3. Carefully pull the DSP board (3) straight out from the power board (5). Do not bend the pins.
Note: Instructions for removing the DSP board are the same for both CE and CSA models. The power
board (5) shown below is a CSA model.
4. Disconnect the ribbon cable from the ribbon cable connector (6) on the back of the DSP board. Set the DSP board
aside.
If the power supply is a 380/400V CE model, continue to the next page.
If the power supply is a 200-600V CSA model, proceed to page 8.
