Section VI - GROUND OPERATIONS
ELECTRICAL SYSTEM
CAUTION:
IF IT IS INTENDED TO PARK THE AIRPLANE IN AMBIENT TEMPERATURES BELOW
-10° C FOR A PERIOD OF 12 HOURS OR MORE, THE AIRPLANE BATTERIES MUST
BE REMOVED TO A WARMER ENVIRONMENT.
CAUTION:
TO PREVENT EXCESSIVE DISCHARGE AND POSSIBLE DAMAGE TO NO. 1
BATTERY, MAKE SURE THE MISCELLANEOUS LIGHTS (ROOF, STEP, REFUEL
PANEL ETC.), ARE SWITCHED OFF. OPERATE EITHER THE ROOF LIGHT SWITCH
(PANEL DA) OR THE ROOF/STEP LIGHT SWITCH (LH FORWARD CABIN
BULKHEAD) WHEN GROUND POWER IS ON AND/OR WHEN THE AIRPLANE IS TO
BE LEFT UNATTENDED FOR LONG PERIODS.
NOTES:
1. To avoid drain on airplane batteries it is recommended that testing of electrical services
be performed using external ground supply incorporating overvoltage protection.
2. For external starts, a ground power unit capable of supplying 28 VDC with a minimum
output of 42 kW (short term capability of 28 volts x 1500 AMPS) having a limiter
operating at 1100 AMPS must be used.
GENERAL
Primary DC power distribution is effected by busbars designated PS1, PS2, and PE. During ground
servicing, the busbars can be energized from the APU generator or ground supplies. PE busbar may
also be energized from the airplane batteries, provided their use is severely restricted.
ENERGIZE DC BUSBARS
WARNING:
MAKE SURE THE THRUST REVERSERS ARE STOWED AND THE THRUST
REVERSER LEVERS IN THE FLIGHT COMPARTMENT ARE AT THE STOW
POSITION BEFORE ENERGIZING THE DC BUSBARS.
CAUTION:
THE APU MASTER SWITCH SHOULD NEVER BE LEFT IN THE ON POSITION WITH
THE APU NOT RUNNING BECAUSE FUEL PUMP CAVITATION CAN OCCUR WITH
SUBSEQUENT PUMP DAMAGE OR FAILURE.
To energize the DC busbars refer to Figures 12 and 12A. The external ground supplies are connected
to the airplane electrical system via a three pin plug located on the right side rear fuselage (Figure 13).
