Pins 17, 19, and 21 of P601 are internally connected to form AIRCRAFT POWER 1. Pins 23, 25, and 27
of P601 are internally connected to form AIRCRAFT POWER 2. AIRCRAFT POWER 1 and
AIRCRAFT POWER 2 are “diode ORed” to provide power redundancy. The same applies to pins 29/31
and pins 33/35 of P605. Use of more than one AIRCRAFT POWER and POWER GROUND pins is
required for installations where current through a single connector pin will exceed 5A.
