Earth connections
To reduce the length of individual conductors that must be connected to earth we
recommend using an earth busbar located as near as possible to the drive.
The busbar must be made of copper to ensure low inductance. It must also be mounted on
insulated fixings. The adjacent table shows minimum dimensions according to length.
