Grounding switch
The grounding switch is a safety device that enables safe access to the medium voltage
compartments of the drive.
The drive is equipped with one of the following switchgear:
- Grounding switch (1 in Fig. 3-9)
- Combined input disconnector and grounding switch (2 in Fig. 3-9)
The input disconnector and the grounding switch are mechanically coupled and operated with
a single lever.
Figure 3-9: Switchgear of the drive
The switch is electro-mechanically interlocked with a discharge monitoring circuit that
prevents turning of the switch while the DC-link capacitors are still charged. When the drive is
grounded, the DC link of the drive is connected to the PE ground busbar.
