Bearings or seals must not come into contact w ith the solvent - m aterial
damages.
Afte r a long storage period (> 1 year) you have to check w hether m oisture has
entered the m otor. For this purpose, measure the insulation resistance (m easuring
voltage 500 V dc). In case o f values <1kQper volt of rated voltage, dry the w inding.
