Drive seasonal operation

This chapter contains instruction for drive special preventive maintenance when drives
standby more than 2 months. The objective is to avoid malfunction or damage
components when the drives restart up after a long time storage, further to improve
operating efficiency and extending the life of the drives. The example practice is heating
application which drives only operate in winter days.

Shutting down the drive for maintenance


See chapter Maintenance, shutting down for maintenance for instructions. Follow the
established shutdown procedure by using local operator panel of the drive.

Maintain the drive for preservation


During standby, it is important to make the drive protected from harsh ambient conditons of
dust, temperature and himidity. Keep the temperature in E-house be relative stable in the
range of 0?C to 50?C, and relative humidity be lower than 70%. Recommended
maintenance soultions.
•
Prefered solution: put silica gel bags (type of desiccant) inside the cabinets. Silica gel
bags should not be in direct contact with metal parts because they can cause
corrosion after saturation. The required bag quantity can be calculated based on
protection capacity and cabinet dimension. Close all the doors and cover the drive with
plastic film and seal it by tape as tight as possble. That will provide protection against
dust, salty air or pest during storage.
ABB offered desiccant is 3ABD00005991 (500g/bag). Refer to the minimum desiccan
quantity based on door width.

•
Alternative solution: cover and seal cabinet inlet/outlet and fan box with plastic or
waterproof clothes. That will alleviate the impact from dust, salty air or pest during
storage.

Maintain the drive before restarting up


The maintenance actions can be done by end users to to avoid potential malfuction or
damage components when drive restarting up. Following the chapter of Mainteance
schedule (Years from start-up) to do the recommended maintenance and component
replacement. It is mandatory to complete the checklist before restarting up can take place.
Visual inspection and take maintenance actions if need
1 No dust in E-house
2
Cleaning heatsinks with an ESD vacuum cleaner. It is prohibted to replace PEBBs or open
PEBBs. If really needed, contact ABB.
3
Air inlet and outlet are clean
4
All air filter mats are clean. Otherwise, replace with new ones from ABB. It is prohibited to wash
the filter mats because the tissue structure will be destroyed
5
No dust and corrosion in cabinet
6
No tools and foreign objects are left inside the cabinets. Don't forget move out the desiccants
in the cabinets.
7
No condensing in cabinet
Cable and connector
1 Fully inspect tighteness of terminals, connectors connection and visual damage of cables.
Minimum desiccant quantity
1x500g
