Preparation
Remove the corrosion protection from the shaft ends and flanges. If necessary, remove dirt
using standard cleaning solvents.
(
Stop!
Bearings or seals must not come into contact with the solvent − material
damages.
After a long storage period (> 1 year) you have to check whether moisture has entered
the motor. For this purpose, measure the insulation resistance (measuring voltage
500 V
DC
). In case of values
£1kWper volt of rated voltage, dry the winding.
