Unidrive M Modular Installation Guide

Issue Number: 2

6.1.3 Ground connections

On a Unidrive M size 9, 10 and Rectifier, the supply and motor ground
connections are made using an M10 bolt at the top (supply) and bottom
(motor) of the drive. See Figure 6-5

Unidrive M size 9E/10E/9A ground

connections

on page 58.

The supply ground and motor ground connections to the drive are
connected internally by a copper conductor with a cross-sectional area
given below:

9E/10E: 75 mm

9A/9D/10D: 120 mm

Rectifier: 128 mm
