5.6 Installing the machine

5.5.2

Flatness of the supporting surfaces for conventional motors

5.5.3

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.
5.6 Installing the machine
5.6.1

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
5.6.2

Aligning the machine to the driven machine and mounting

5.6.2.1

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.
