 Make sure the ambient temperatures for the mains fuses specied by the producer
are not exceeded.
WARNING!
Risk of death by fire!
 Provide separate fuses for each inverter.
 Do not attach any loads between inverter and fuse.
 If you use an external leakage current circuit breaker (RCD switch), you must comply
with the following connection conditions:
– Use an A type RCD (residual current device) switch with a rated fault current of at
least 100 mA.
– In PV power plants with high leakage capacities, an RCD switch with a rated fault
current of at least 300 mA. must be used.
