5.2 Maintenance
All technical devices, drives as well, need a certain amount of care-taking and failure preventive
maintenance. To maintain trouble-free operation of the VACON
®
drives, environmental conditions,
as well as load, line power, process control, etc. have to be within specifications, determined by
manufacturer.
If all conditions are in accordance with the manufacturer's specifications, there are no other
concerns, but to provide a cooling capacity high enough for the power- and control circuits. This
requirement can be met by making sure, that the cooling system works properly. Operation of
cooling fans and cleanness of the heat sink should be verified regularly.
Regular maintenance is recommended to ensure trouble free operation and long lifetime of the
VACON
®
drives. At least the following things should be included in the regular maintenance.
It is also recommended to record all actions and counter values with dates and time for follow up of
maintenance.
