Installation

Fig. 36

Busbars mounted at an angle

Mounting busbars

Adjust the busbars 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

busbars.

Tightening torque M10: 35 ±4 Nm

Tightening torques apply to greased threads only.

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 herein and are

performed by the customer.
