4. Procedure
Subtask 22-67-00-710-050-A ** ON A/C NOT FOR ALL

A. Operational Test of the Electrical Supply during Emergency Transient.

ACTION	RESULT
1.On the overhead panel, on the EMER ELEC PWR panel 21VU: Open the guard and push the EMER GEN TEST pushbutton switch.
2.On the panel 49VU: Open the circuit breaker 5CC1.	On the lower ECAM display unit: The message INOP SYS FAC1 comes into view approximately 10 seconds after the opening of the circuit breaker.
3.On the overhead panel, on the EMER ELEC PWR panel 21VU: Open the guard and release the EMER GEN TEST pushbutton switch.
4.On the panel 49VU: Close the circuit breaker 5CC1.	On the lower ECAM display unit: Make sure that the message INOP SYS FAC1 disappears.

5. Close-up
Subtask 22-67-00-860-051-A ** ON A/C NOT FOR ALL

A. Put the aircraft back to its initial configuration.
