R C. Flight Configuration Precautions
(1) If the electrical power is not necessary for other maintenance tasks, de-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002). Then it is not necessary to operate the LGCIU circuit breakers.
R R R (2) If the electrical power is necessary, do the flight configuration precautions with electrical power (Ref. TASK 32-00-00-860-001) before you open the circuit breakers.
D. Make sure that this(these) circuit breaker(s) is(are) open, safetied and tagged
