Grounding of Power Unit
The mains cables are connected to the protective ground of the switchgear enclosure.
We recommend connecting 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 3-3).

Cable Installation and the UL Standards
To meet the UL (Underwriters Laboratories) regulations, a UL-approved copper cable with a
minimum heat resistance of +140/167°F (+60/75°C) must be used.
The tightening torques of the terminals are given in Table 3-4.
