4. Unscrew the three screws of the blanking plate.
Remove the plate.
5. Insert the Braking Module where the cover used to be and secure it using the three
screws (from step 4).
6. Attach the adapter bar to the DCNA using a nut, so that the busbar cannot be twisted. For
this purpose, a small bolt is attached to the adapter bar, which must be located on the
lower side of the DCNA connection.
7. Secure the connecting cable to the DC link with two screws (Braking Module connection)
and two nuts (DC-link connection).
Carry out the subsequent steps in reverse order from steps 1 – 3.
An opening above the connections for the braking resistor (R1, R2) is provided in the cover
for connecting the cable to the braking resistor.
Note
Pay attention to the tightening torques
The tightening torques specified in the table "Tightening torques for screw connections" must
be observed.
