Adding a Cabinet
to an Existing GPS
System with 
Distributed
Architecture.
When interconnecting the DC power bus connections between the new
cabinet and the existing system, a small arc may be produced. In order
to avoid this, some precautionary steps are required. Refer to Figure 6-4
for this procedure.
1. Install the new cabinet as shown in Figure 5-12.
2. Install the cabinet ground cable per Figure 5-13.
3. Make sure there are no rectifiers installed in the new cabinet.
4. On the BLJ board of the new cabinet, pull fuses F1 (2 amp fuse for
ABS) and F2 (1-1/3 amp fuse for BLJ power). Note F3 and F4 are
spares for F1 and F2 respectively.
5. If the new cabinet contains Low Voltage Load Disconnect (LVLD)
panels as shown in Figure 8-13, disconnect the cable connected to
P2 (top connector) on the EBV control board(s).
6. If the new cabinet contains a blue battery connection panel
equipped with Low Voltage Battery Disconnect (LVBD)
contactor(s) as shown in Figure 11-5, disconnect cable connector
J300 (middle connector) on BJN control board(s).
7. Install the intercabinet bus bars and torque connections as specified
in Figure 6-4.
8. Install the bus bar shield as shown in Figure 6-4.
9. Reconnect cable connection(s) J300 to BJN control board(s) on the
LVBD (blue) panel.
10. Reconnect cable connection to P2 on EBV control board of all
LVLD panels.
11. Reinstall fuses F1 and F2 on BLJ board.
