# No Power (NP)

NP.1The ETCS on-board is in the No Power (NP) mode when the equipment is not powered.

The notion of responsibility of the driver is not relevant for this mode.

The emergency brake is permanently commanded in NP mode.

NP-[V].1If it is required to move a loco in NP mode as a wagon, ETCS brake command must be overridden by external means.

## NP.ONPower on the ETCS on-board (ON)

NP.ON-[V].1Train specific clauses to indicate how to power on the ETCS on-board equipment.

NP.ON.1When the ETCS on-board equipment is powered on, the mode changes to Stand By, see section SB - Stand By (SB).

NP.ON.2 Additionally to the transition mentioned previously (i.e. NP → SB), the following mode transition can be triggered from NP mode:

- IS mode. The transition is triggered when the driver isolates the ETCS on-board equipment, see section IS.ENT Entering Isolation mode (ENT).
