16 - Installation and Alignment
The foundation and the mounting bolts must be dimensioned to withstand a sudden mechanical
torque, which occurs every time the machine is started, or at short circuit. The short circuit force
is a gradually damped sine wave that changes direction. The magnitude of these forces is
mentioned on the dimensional drawing of the machine.
Vertical flange mounted machines are equipped with a mounting flange according to IEC-
standard publication 60072. The flange of the machine should always be mounted to an opposite
flange on the foundation.
A mounting adapter is recommended to enable an easy coupling connection and inspection
during operation.
Prepare the machine for installation as follows:
• Measure the insulation resistance of the winding before any other preparations are done as
described in Chapter 3.3.1 Insulation resistance measurements
• Remove the transport locking device when applicable. Store it for future use. See Chapter
3.3.2 Disassembly of the transport locking device for further instructions
• Verify that the grease available is according to the specification on the bearing plate, see
Chapter 2.1.2 Bearing plate. Additional recommended greases can be found in Chapter
7.5.1.5 Bearing grease
• Remove the anti-corrosive coating on the shaft extension, and machine feet with white
spirit
• Install the coupling half as described in Chapter 3.3.4 Assembly of the coupling half
• Check that the drain plugs at the lowest part of both ends of the machine are in open
position, see Chapter 3.3.6 Drain plugs.
Before a machine is started up for the first time, after a long period of standstill or within the
scope of general maintenance work, the insulation resistance of the machine must be measured.
This includes measuring the stature winding and all auxiliary devices. For machines equipped
with slip ring, the measuring also includes the rotor winding, see Chapter 7.6.4 Insulation
resistance test.
Some machines and all machines with sleeve or roller bearings have transport locking devices
installed. For machines with sleeve or cylindrical roller bearings, the transport locking device is
made of a steel bar attached to both the bearing shield on the D-end and to the end of the shaft
extension.
The transport locking device has to be removed prior to installation. The shaft extension has to
be cleaned of its anti-corrosive coating. The locking device should be stored for future use.
