Ground connection
MANDATORY. It is up to the system integrator to meet all the requirements
of local and national electrical codes as well as all the regulations
applicable regarding the grounding of the whole unit.
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.
F. H8/10
Ground connection.
The tightening torque must be between 2.32.8 Nm.
MANDATORY. Take a ground cable (as short as possible) from each module
to each main machine ground point.
MANDATORY. In order to ensure compliance with the European Directive
on Electromagnetic Compatibility 2004/108/EC, it is a must to:
• Verify that all the requirements of local and national electrical codes are
met as well as all the regulations applicable regarding the grounding of
the whole unit.
• Power the system through “MAINS FILTER A”.
• Secure the filter onto a metallic support with a good contact on its
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
chapter 7. CABLES.
