DANGER!
Danger to life due to fire.
When a producer (inverter) and a consumer are connected to the same line circuit breaker,
the protective function of the line circuit breaker is no longer guaranteed. The current from
the inverter and the grid can accumulate to overcurrent which is not be detected by the line
circuit breaker.
• Never connect consumers between the
inverter and the line circuit breaker
without protection.
• Always protect consumers separately.
NOTICE!
Damage to the inverter by using screw type fuse elements as a load
disconnection unit.
A screw type fuse element, e.g. D system (Diazed) or D0 system (Neozed) is not a load
disconnection unit, and thus must not be used as a load disconnection unit. A screw type
fuse element is only used as cable protection.
When disconnecting under load using a screw type fuse element, the inverter can be
damaged.
• Use only a load disconnection switch or a line circuit breaker as a load disconnection
unit.
