DANGER!
Danger to life due to fire.
When more than one inverter is connected to the same line circuit breaker, the protective
function of the line circuit breaker is no longer guaranteed. It can result in a cable fire or
the destruction of the inverter.
• Never connect several inverters to the same line circuit breaker.
• Comply with the maximum permissible fuse protection of the inverter when selecting
the circuit breaker.
