Safety instructions
Note
Note also the technical data on the rating plates on the motor enclosure.
NOTICE
Damage to the motor
To avoid material damage, before commissioning, check whether the correct direction of
rotation of the machine has been set on the customer side, e.g. by decoupling from the
driven load.
5.3.3
Insulation resistance
5.3.3.1
Insulation resistance and polarization index
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:
