Preliminary Steps
Before replacing the main control board, shut off the power; lockout/tagout
the unit; and wait five minutes for all voltage to discharge. Open the bay
door to the power structure. Verify that the board is labeled with the
appropriate catalog number (see the example in Figure 1).

Board
1. Using a meter, test the voltage across the AC line, across the DC bus, and
across the terminals and test points on the main control board.
2. Put on the ESD wrist strap and attach it to the PE busbar (back
grounding bar in the bottom of the unit).
3. Disconnect J2, J3, J9, J10, J11, J12 from the main control board (as
shown in Figure 2).
4. Disconnect TB1 from the main control board.
5. Remove the screws which mount the main control board to the mounting

For example, if the data nameplate for an RGU
has a Series B identifier (or 3 CT current monitoring),
the new main control board should be labeled with
the catalog number 2364-SPM03A.

ATTENTION: If there is any voltage present, remove the
source of the voltage. Check for voltages again before
proceeding to the next step.
