 The FDIU is supplied from the busbar via the circuit breaker 8TU. The power interlock controls the power supply of the DFDR and QAR. 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.

The FDIMU is supplied from the AC-NORM busbar through the circuit breaker 5TV.

 -
The DFDR is supplied from the AC-NORM busbar through the circuit breaker 7TU. The operation of the DFDR is controlled by the power-interlock.

 -
The LA is supplied from the DC-NORM busbar through the circuit breaker 9TU.

 -
The power-interlock relays are supplied from the DC-ESS busbar through the circuit breaker 4RK.
