  1-5 Product Overview
  
  In order to conform with the specified generic EMC standards the motor cable must be screened and the screen connected to both the motor frame and the motor cable clamp.
  
  4-2 Electrical Installation
  
  Motor Wiring
  
  Motor Cable Clamp
  
  To meet the generic EMC Standards and minimise the electrical interference, connections between the Inverter and the motor must be made using screened cable. The screens must be connected to the motor frame and to the motor cable clamp (PE). The motor protective earth conductor should be connected at the drive end to the motor PE point.


I would interpret that as requiring just one connection to earth at the VFD. The VFD should be connected to earth by using a conductor from the VFD to the earth connection point for the building. That point is probably located at the power distribution panel.
