3.2. Storage
Measures to be taken by the customer or other part:
• The motor should be left on the pallet.
• The pallet with the motor should preferably be stored indoors and shall be placed on a vibration-free,
flat and well-drained surface.
• The pallet with the motor should be kept dry, dust-free and protected from rain and moisture.
• If the motor is equipped with heating elements in the stator winding, ensure they are electrically
connected to prevent possible condensation.
• It is recommended that the shaft is rotated monthly to prevent grease migration.
• All motors leave the factory with an anti-corrosion coating, such as Tectyl 506, on the shaft extension
and mounting surfaces. The coating should be inspected by the customer and re-applied if necessary.
3.3. Removal of Tectyl before commissioning
The corrosion protection coating, such as Tectyl 506, must be removed before commissioning. Ensure
that corrosion protection coating is removed for mating surfaces, e.g., shaft and flange surfaces. Tectyl
506 can be removed with Tectyl Biocleaner, Tectyl HPS solvent borne thinner, vapor degreasing, a hot
alkaline wash or low-pressure steam.
3.4. Insulation resistance check
Measure insulation resistance before commissioning, after long periods of standstill or storage when
winding dampness may be suspected.
Insulation resistance should be used as a trend indicator to determine changes in the insulation system.
insulation resistance is important to know the condition of the insulation system. Typically, the insulation
resistance value is not attained, the stator winding is too damp and must be oven dried. Please contact
your local ABB sales office for technical support.
NOTE: To avoid risk of electric shock, the motor frame must be grounded and the windings should
be discharged against the frame immediately after each measurement.
