(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.
(2)
If the electrical power is necessary, do the precautions for flight configuration with electrical power before you open the circuit breakers (Ref. TASK 32-00-00-860-001).
