I have a few questions regarding some issues.
Let’s suppose that an electrician/ engineer electrician is working in a production area , where we have different automatic or semi automated industrial machines with a consumption per each machine is about 2-5A.Power supply is 380V a.c. or 220V a.c.
1. What kind of authorization is necessary for the electrician/engineer electrician in order to make maintenance operations or interventions, like: changing a relay, replace a sensor, make some small modification in electrical cabinet ( at 380 V a.c to 24 Vd.c.)
2. If the production area is build also industrial machines and the electrical cabinet is made by the electrician and the project by electrical engineer, what kind of authorizations is necessary to functions this machine? The consummation of this machines is 2-5A at 380V a.c or 220V a.c.
3. For programming the machines I thing is not necessary any kind of authorization.
Thank you for the support.
