Terminals in the Interface Panel
When connecting the interface panel, three terminal boards are needed for the power signals; a special
cable is also needed for the measure signals, which is ready to be connected to the control board terminals
of the regenerative drive.

Connection of NO auxiliary
contact of the filter capacitor
safety switch.
Connect to terminals 23 and 18 in the control
board of the regenerative drive. The Rgn drive
starts only when this contact closes; alarm

Vrs
Supply mains Vrs voltage
measure.
Connect to the terminal board in the control
board of the regenerative drive through the
cable supplied with the interface panel.
Ground the cable braiding through the cable
glands located in the regenerative drive.

GND
Ground.
NOTE
If multiple filter capacitor units are installed, close all switches located on the
interface panel to close the contact on terminals 1 and 2 in M3 and to allow
the regenerative drive to start.
