10.5.3.2 Physical Arrangement
The location of JPDE is not critical in a panel. Connector P1 transmits feedback signals to a board hosting a PPDA I/O pack.
Connector P2 receives feedback from other power distribution boards and passes the signals out of P1 to the PPDA. If a cable
connection from JPDE to a board containing PPDA is planned, consideration should be given to the feedback cable routing
between JPDE P1 and the P2 connector on the board receiving the feedback cable.
10.5.3.3 Application Notes
JPDE can be used with one or two power supplies to create a dc power system for terminal boards and other system loads.
When this is done, float the dc power system and use the grounding resistors on JPDE to center the bus on earth. This permits
detection of ground faults through the PPDA bus voltage feedback. Jumper JP1 is required to be in place, connecting the
centering resistors to earth. When JPDE is used to distribute battery power, it is supplied with a dc circuit breaker and a 30 A
input filter.
