6 Maintenance
Attention! Disconnect the unit from the power supply prior to all
maintenance work. Always observe the safety instructions!
(See chapter 1.)
The INV consists of state-of-the-art components which are almost
non-wearing. We do, however, recommend regular visual and
functional tests of the unit to maintain its continuous availability and
operational reliability.
When visually inspecting the unit, check whether:
• there is any mechanical damage or foreign bodies are present,
• any conductive dirt or dust has accumulated in the unit, and
whether
• accumulation of dust affects heat supply and dissipation.
If large quantities of dust have accumulated, the unit should as a
precaution be cleaned with dry compressed air, in order to ensure
adequate heat dissipation.
The intervals at which visual checks should be performed are largely
determined by the site conditions. The unit must not be operated in
an aggressive atmosphere.
