DANGER
Danger to life as a result of insufficient grounding
The drive must be grounded to ensure that it operates safely and reliably. If the drive is
operated with insufficient grounding, then the protection and monitoring functions can fail.
Death, serious injury, or material damage will result.
● To ensure the correct functioning of the protection and monitoring equipment, ground the
device.
A grounding busbar is located in the lower section of the cabinets ②. The grounding busbar is
used to ground the components installed in the cabinet and to ground the cabinet itself.

grounding busbar ②.
