5.3.3 Machine frame mounting feet (special design)
Please note that when the terminal box is mounted at the NDE (option H08), dimension C
can deviate from EN 50347.
To comply with dimension C according to EN 50347, for machines with double or triple holes
at the NDE, use the appropriate screw bore.
5.4 Installing the machine
5.4.1 Preconditions for smooth, vibration-free operation
Preconditions for smooth, vibration-free operation:
● Stable foundation design
● Precise alignment of the machine
● Correct balancing of parts to be fitted to the shaft end.
● Vibration values in compliance with ISO 10816-3
5.4.2 Aligning the machine to the driven machine and mounting
5.4.2.1 Selecting bolts
● Unless specified otherwise, use fixing screws with at least strength class 8.8 to ISO 898-1
to ensure that the machine is securely mounted and to transmit the torque-generated
forces.
● When selecting the bolts and the design of the foundation, take into account the
maximum forces occurring in the case of a fault such as short circuit or system transfers
in phase opposition, etc.
Request the foundation force values from the Service Center if required.
