General safety and application notes for Lenze power supply modules
Maintenance and servicing
The regenerative power supply modules are maintenance−free if the prescribed operating
conditions are observed.
If the ambient air is polluted, the ventilation slots of the regenerative power supply module
may be blocked up. For this reason a regular control of the ventilation slots is necessary.
Blocked ventilation slots must only be cleaned with a vacuum cleaner, never use sharp or
peaked objects!
Waste disposal
Recycle metals and plastics. Dispose of printed board assemblies according to the state of
the art.
The product−specific safety and application notes in these Operating Instructions must
also be observed!
