When installing a new unit, disconnect the motor (U / T1, V / 
T2, W  / T3) cables to prevent damage to the frequency 
converter. 
Measure  the  insulation  resistance  of  the  motor  windings 
(each phase to ground). Insulation resistance requirement for 
new motor: 
Cold motor (10..40 °C):  ≥ 5 MΩ 
Warm motor (40 °C or more):  ≥ 1 MΩ 
If insulation  resistance  is less  that requirement the motor 
shall be dried.
