Outside Tunnel (UA and UJ):
- The presence of RP is not necessary for any change of module or electromechanical intervention except in case of intervention on the water circuits. In this case, the authorization of RP is necessary before any intervention. (1)
Tunnel:
- The presence of RP is always necessary. It is important to indicate the purpose of the intervention (water circuit or module change).

The presence of RP is not necessary.
Except in case of intervention on the water circuits, the authorization of RP is necessary before any intervention. (1)
