When more than one inverter is connected to the same miniature circuit-breaker, the
protective function of the miniature circuit-breaker is no longer guaranteed. This can result
in a cable fire or destruction of the inverter.

• Observe the maximum permissible fuse protection of the inverter when selecting the
miniature circuit-breaker.
