5.9.4.4 GROUNDING
For safety reasons, proper operation and to reduce electromagnetic
emission, the drive and the motor must be grounded on the installation
location. A star connection is acceptable but it is not the preferred system.
• The cross-section of the ground cable must be suitable to the regulations
of the country in which the drive will be installed.
• The screen of the power cables must be connected to the PE terminal of
the drive to meet the safety requirements.
• In multi-motor applications do not connect the grounding cables of
the drives in series.
• The electrical panel must include its own ground bus bar, connected
to the ground system, to which connect all the devices.
• The ground connection must be as short as possible.
• The ground of the drive must be separated from the ground of
other devices.
• The RFI disturbances require a large ground bus bar because of
the skin effect.
• The screen of the power cables can be used as ground cable only if
it has an adequate cross section complying with safety standards.
