The interface panel must be used based on the size of the regenerative drive.
The interface panel includes the following: resistors of pre-charge capacitors installed on the DC-bus inside
the drive; capacitors of the component filter at the commutation frequency and the relevant safety switch;
measure circuits of the mains voltage.
Figure 6 shows the block-diagram of the interface panel.

NOTE
Based on the drive size, the interface panel can contain up to 5 filter capacitor
units. Each capacitor unit is provided with a safety switch.
