NOTE!
The national regulations of the grid
operator or other factors may require
a residual current circuit breaker in
the AC connection lead.
For this situation, a type A residual
current circuit breaker is generally ad-
equate. Nevertheless, false alarms can
be triggered for the type A residual-
current circuit breaker in individual
cases and depending on local condi-
tions. For this reason, in accordance
with national legislation, Fronius re-
commends that a residual-current cir-
cuit breaker with a tripping current of
at least 100 mA suitable for frequency
converters be used.
IMPORTANT!
As a maximum, the inverter can be
used with an automatic circuit breaker
C 32 A.
