Long Term Storage (More Than 2 Months) - ABB AMA Manual

Manual for High Voltage Process Performance Motors

2.5.2 Long term storage (more than 2 months)

12 - Transport and Unpacking
• Covered, as to completely prevent rain from entering the machine. The cover should allow
ventilation of the machine
• Placed on at least 100 mm (4") high rigid supports, as to make sure that no moisture can
enter the machine from below
• Provided with good ventilation. If the machine is left in its transportation package, large
enough ventilation openings must be made in the package
• Protected from harmful insects and vermin.
Use checklists in Chapter 2 Storage in Appendix COMMISSIONING REPORT.
In addition to the measures described with short-term storage, the following should be applied.
Measure the insulation resistance and temperature of the windings every three months, see
Chapter 7.6 Maintenance of stator and rotor windings.
Check the condition of the painted surfaces every three months. If corrosion is observed,
remove it and apply a coat of paint again
Check the condition of anti-corrosive coating on blank metal surfaces (e.g. shaft extensions)
every three months. If any corrosion is observed, remove it with a fine emery cloth and perform
the anti-corrosive treatment again
Arrange small ventilation openings when the machine is stored in a wooden box. Prohibit water,
insects and vermin from entering the box, see Figure 2-7 Ventilation holes.
Use checklists in Chapter 2 Storage in Appendix COMMISSIONING REPORT.
