It is, however, acceptable to connect two or more auxiliary power supply
boards in parallel (e.g. for redundancy), as long as the current consumption
of the external equipment is less than the rating of one board. This means
that, even if only one auxiliary board is functioning, it will still be able to
supply the current requirements of the external equipment.
Two different types of auxiliary DC output connector have been fitted to
the PMU. The pin allocations for the 8-way connector fitted to PMUs
manufactured before August 2004 are given in the following table. Note
that pins 1 to 4 and pins 5 to 8 on this connector are linked.
The pin allocations for the 2-way connector fitted to PMUs manufactured
from August 2004 onwards are given in the following table.
