Ground Handling

Application of External Power

An external power receptacle, located just aft of the cowl on the left side of
the airplane, permits the use of an external power unit for cold weather
starting and maintenance procedures.
If external power will be used to start engine, keep yourself, others,
and power unit cables well clear of the propeller rotation plane.
To Apply External Power to Airplane
In accordance with the manufacturer's recommendation, external
power should not be used to start the airplane with a dead battery
or to charge a dead or weak battery in the airplane. The battery
must be removed from the airplane and battery maintenance
performed in accordance with the appropriate AMM procedures.
1. Ensure external power unit is regulated to 28 VDC.
2. Verify BAT and AVIONICS power switches are set to OFF.
3. Plug external power unit into the receptacle.
4. Set BAT 1 switch to ON. 28 VDC from the external power unit will
energize the main distribution and essential distribution buses. The
airplane may now be started or electrical equipment operated.
5. If avionics are required, set AVIONICS power switch ON.
If maintenance on avionics systems is to be performed, it is
recommended that external power be used. Do not start or crank
the engine with the AVIONICS power switch 'on.'
