The FDIU is supplied from the busbar via the circuit breaker 8TU. The power interlock controls the power supply of the DFDR. The LA is connected to the 28 V DC bus, via the circuit breaker 9TU. The supply of the power interlock relays is achieved via the circuit breaker 4RK. The maximum power consumption and the busbar connection is as listed below.
