2.9 Maintenance

Danfoss frequency converter models up to 90 kW are
2 2
maintenance-free. High-power frequency converters (rated
at 110 kW or higher) have built-in filter mats, which require
periodic cleaning by the operator, depending on the
exposure to dust and contaminants. Maintenance intervals
for the cooling fans (approximately 3 years) and capacitors
(approximately 5 years) are recommended in most
environments.

2.9.1 Storage

Like all electronic equipment, frequency converters must
be stored in a dry location. Periodic forming (capacitor
charging) is not necessary during storage.
It is recommended to keep the equipment sealed in its
packaging until installation.
