Chapter 5 Commissioning and Start-up
5.1 General
A commissioning report is a vital tool for future service, maintenance and fault finding.
The commissioning is not to be considered finalized before an acceptable commissioning report
has been documented and filed.
The commissioning report has to be available in warranty requests in order to obtain warranty
for the machine. For contact information, see Chapter 9.1.5 After Sales contact information.
The recommended commissioning report can be found in Appendix COMMISSIONING
REPORT.
5.2 Check of mechanical installation
Check alignment of the machine prior to commissioning:
• Go through the alignment report and ensure that the machine is accurately aligned
according to ABB alignment specifications in Chapter 3.6 Alignment
• The alignment protocol should always be included in the commissioning report
Check that the machine is properly anchored to the foundation:
• Check for cracks in the foundation and the general condition of the foundation
• Check the tightness of the mounting bolts.
Additional checks, when applicable:
• Check that the lubrication system is commissioned and is running before the rotor is turned
• If possible, turn the rotor by hand and make sure that the rotor turns freely and that no
abnormal sound can be heard
• Check the assembly of the main terminal box and cooling system
• Check the connection of oil and cooling water pipes and check for leaks when running
• Check pressure and flow for oil and cooling water.
5.3 Insulation resistance measurements
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,
see Chapter 7.6.4 Insulation resistance test.
5.4 Check of electrical installation
The power cables can be permanently connected to the terminals in the main terminal box when
the stator insulation resistance has been measured, see Chapter 7.6.4 Insulation resistance test.
Check connection of power cables:
• Check that the cable lug bolts are tightened with proper torque
