● Check the insulators, connectors and cable connections in the terminal box.
● Replace any damaged components.

serious injury or material damage.
Replace damaged components.
9.1.14
Measuring the insulation resistance during the course of maintenance work
Measuring the insulation resistance and polarization index (PI) provides information on the
condition of the machine. It is therefore important to check the insulation resistance and the
polarization index at the following times:
● Before starting up a machine for the first time
● After an extended period in storage or downtime
● Within the scope of maintenance work
The following information is provided regarding the state of the winding insulation:
● Is the winding head insulation conductively contaminated?
● Has the winding insulation absorbed moisture?
As such, you can determine whether the machine needs commissioning or any necessary
measures such as cleaning and/or drying the winding:
● Can the machine be put into operation?
● Must the windings be cleaned or dried?
Detailed information on testing and the limit values can be found here:
"Testing the insulation resistance and polarization index" (Page 41)
9.1.15
Touch up any damaged paintwork
If the paint is damaged, it must be repaired in order to protect the unit against corrosion.
Note
Paint system
Contact the Service Center (Page 121) before you repair any paint damage. They will provide
you with more information about the correct paint system and methods of repairing paint
damage.
