Step g must be followed carefully. Failure to comply will result in damage to the airplane.
g. Carefully line up the external power cart plug with the airplane receptacle (8). Place the plug directly on the receptacle.
Do not wiggle or twist the plug.
h. Place the power cart unit switch to ON. The SCM EXT PWR light (1) on the
À
ight engineer SCM POWER control
panel should come on.
i. Place the EXTERNAL switch (2) on the
À
ight engineer SCM POWER control panel to ON. The SCM EXT PWR
CONTROL light (5) at the SCM external power receptacle should come on.
1.3.13 Disconnecting SCM External Electrical Power (AF68-0213 and AF68-0216).
(See Figure 1-29.) Use the
following procedure to disconnect SCM external power.
a. Place the EXTERNAL switch (2) on the
À
ight engineer SCM POWER control panel to OFF.
Ensure that the external power cart switch is OFF. Failure to comply could cause injury to personnel.
b. Place the external power cart switch to OFF.
c. Disconnect the external power cart plug from the SCM external power receptacle (8).
d. Close the SCM external power receptacle door (6).
1.3.14 Cargo Compartment AC Power Provision. The AC power provision in the cargo compartment allows two or
more airplanes to be serviced by one AC electrical power source. Any AC electrical power source connected to the main AC
tie bus will supply power to the cargo compartment AC power provision. Attach power cables to the lugs on the cargo
compartment AC power provision in the airplane with power source to the AC power provision in the cargo compartment of
the airplane receiving the electrical power.
1.3.15 Circuit Breaker Locations and Deactivation Requirements.
Circuit breakers are located throughout the air-
plane. These circuit breakers provide protection of the various airplane systems and equipment from electrical current
overloads.
a. Circuit breakers shall be opened during maintenance actions as required by applicable technical data. If required,
warning tags or circuit breakers collars shall be attached and documented in accordance with TO 00-20-1. Failure to
comply may cause injury to personnel or damage to airplane.
b. Technical data currently requires a circuit breaker to be opened during maintenance and identi
¿
ed using warning tags.
When the phrase “attach warning tag” for open circuit breakers is used in the applicable technical data, a warning tag
or circuit breaker collar shall be used.
c. Warnings tags are not intended for use on circuit breakers opened for
À
ight. If a system is required to be deactivated
for
À
ight (e.g., thrust reversers, galley oven, etc.), the system will be deactivated using a circuit breaker collar or other
approved method, and an applicable warning statement entered in the AFTO Form/IMT 781A in accordance with TO
00-20-1.
1.3.16 Connecting External Pneumatic Power.
(See Figure 1-30.) An external pneumatic power receptacle is located in
the aft bulkhead in the interior of the left MLG pod at FS 1644 and WL 100. To connect external pneumatic power to the
airplane, use the following procedure:
