Ground connection
The chassis of each modules must be connected to a single point and from
there to the ground terminal of the electrical cabinet. When applying a 10 A
current between this ground point and any of these points, the voltage drop
must not exceed 1 V. Use the washers and nuts supplied with each module
to make the ground connection.
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.
The tightening torque must be between 2.3

2.8 Nm.
MANDATORY. It is up to the system integrator to meet all the require-
ments of local and national electrical codes as well as all the regulations

whole base, good ground connection and as close to the power supply
as possible.
• Make all the ground connections indicated in the figure F. H8/10 with a
cable having a section equal to or greater than the three-phase power
supply and at least 6 mm².
• Always use shielded cables for three-phase motor connections. See
