Measuring the polarization index

1. To determine the polarization index, measure the insulation resistances after one minute

and ten minutes.

2. Express the measured values as a ratio:

PI = R

insul 10 min

/ R

insul 1 min

Many measuring devices display these values automatically following the measurement.

For insulation resistances > 5000 MΩ, the measurement of the PI is no longer meaningful and

consequently not included in the assessment.

(10 min)

/ R

(1 min)

Assessment

≥ 2

Insulation in good condition

< 2

Dependent on the complete diagnosis of the insulation

NOTICE
Damage to insulation
If the critical insulation resistance is reached or undershot, this can damage the insulation

and cause voltage flashovers.
● Contact the Service Center (Page 177).
● If the measured value is close to the critical value, you must subsequently check the

insulation resistance at shorter intervals.

Limit values of the anti-condensation heating insulation resistance

The insulation resistance of the anti-condensation heating with respect to the machine housing

should not be lower than 1 MΩ when measured at 500 V DC.

5.1.4

Prepare the mating faces (IM B3)

● Ensure that the foundation faces are flat and free of contaminations.

Note
Shims
To establish a defined mounting surface, you can order shims (option L31) from our Service

Center.

● Check the dimensions of the mounting-foot holes.
