EXTERNAL POWER
A connector for standard 28 volt DC aircraft
ground power unit (GPU) is located on the
helicopter nose, protected by a small hinged
cover. After a ground power start, both
engines should be operating and the GPU
unplugged prior to placing either generator
on line, due to voltage incompatibility.
BATTERY POWER
If a dual generator failure occurs, the battery is sized to provide a minimum of 30
minutes operation, when powering only the two emergency buses. Power may be restored
to the DC BUSES, using the battery as source, but a reduced operating time will result.
The battery contains three temperature sensors; two provide input to the IIDS warning
and caution displays, while one monitors temperature during external power operation

overtemperature occurs. The battery is attached to the helicopter electrical system
with a standard quick-disconnect plug.
INVERTERS
Two 250 volt ampere, solid state inverters
supply both 115 and 26 volt AC ( alternating
current). Each inverter [No.1 & No.2] is
powered by respective EMERGENCY BUS
1and EMERGENCY BUS 2.
