DANGER!
Danger to life due to fire.
When a producer (inverter) and a consumer are connected to the same miniature
circuit-breaker, the protective function of the miniature circuit-breaker is no longer
guaranteed. The current from the inverter and the grid can accumulate to form overcurrents
that are not detected by the miniature circuit-breaker.
• Never connect consumers between the
inverter and the miniature circuit-breaker
without protection.
• Always protect consumers separately.
NOTICE!
Using screw type fuse elements as load disconnection units can damage the
inverter.
A screw type fuse element, e.g., D system (Diazed) or D0 system (Neozed), is not a
switch-disconnector, and therefore may
not
be used as a load disconnection unit. A screw
type fuse element serves for cable protection only.
When disconnecting under load using a screw type fuse element, the inverter can be
damaged.
• Only use a switch-disconnector or a miniature circuit-breaker as a load disconnection
unit.
