6.1.6 Installation space
Enough free space must be left above and below the AC drive/inverter to ensure practical and
appropriate electrical and cooling connections. The minimum dimensions are given in the table
below. The space left and right to the drive may be 0 mm.
6.1.7 Grounding of power unit
The mains cables are connected to the protective earth of the switchgear enclosure.
We recommend to connect the motor cables to the common PE of the cabinet/cabinet system.
For grounding of the drive itself, use the grounding terminal on the drive mounting plate (see
Figure 39) and tighten the grounding bolt to 13.5 Nm.
