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).

Figure 3-3: Grounding Terminal on Mounting Plate

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.
