IN.3.3 GROUND CONNECTION
The ground connections of the drives (screwed-on plates) must go to a single point and from
there to the ground terminal of the electrical cabinet. When applying a 10A current between
this ground point and any of these points, the voltage drop must not exceed 1 Volt.
When not having a separate ground point, join the plates to the terminal of the Power Supply
module which, in turn, will be connected to Mains Ground.
