2. Unplug reserve battery cable from BATT connector of power supply.
3. Unplug the FG2 plug from the Expansion KSU ground wire.
4. Unplug the DC cable from the DC OUT connector (P16).
5. Remove the FG screw from left side of power supply to free FG wire/terminal and building
ground wire.
6. Unplug the AC power cord from PN2.
7. Remove the seven screws that attach the power supply to the Base KSU. Remove the power
supply.
Power Supply Replacement
1. Set the power supply in its proper place in the Base KSU (see
2. Secure the power supply to the Base KSU with the seven screws.
3. Connect the FG1 wire from the TCOU or TDDU to the FG1 screw on the power supply.
4. Plug the DC cable into the DC OUT connector. The green/yellow wire is on right-hand side.
5. Fasten FG green wire ring terminal and building ground wire to the left side of the power
supply with the FG screw.

Printed Circuit Board (PCB) Installation
This section details Strata DK40i system PCBs installation into the Base and Expansion KSUs.
Also described are optional configuration information and programming considerations for each
PCB.
Base KSU PCBs
The Strata DK40i processor is built into the motherboard (TMAU2) and comes with eight digital
telephone circuits (ports). The line circuits are on the TCOU or TDDU PCBs, which attach to the
P10, P11 and P12 connectors on the TMAU. The PCBs that can be installed into a DK40i KSU are
shown in
