Mounting conductor bars
Adjust the conductor bars in such a way that, before fastening, they lie flat easily and
fit the holes on the contact surfaces of the upper and lower terminal.
Corresponding to the rated current strength, use M10 screws and nuts – strength
class 8.8 – and the appropriate spring elements and washers for connection of the
conductor bars.
Attach the busbars or flexible braid tension-free and torsion-free to the upper and
lower terminals.
Further steps for connecting the prime conductors are not described here and are
performed by the customer.
