NOTE!
National regulations, the grid operator's
specifications or other factors may re-
quire a residual current circuit breaker
in the AC connection lead.
For this situation, a type A residual-current
circuit breaker is generally adequate. Nev-
ertheless, false alarms can be triggered for
the type A residual current circuit breaker
in individual cases and depending on local
conditions. For this reason, in accordance
with national legislation, Fronius recom-
mends that a residual current circuit break-
er with a tripping current of at least 100
mA suitable for frequency converters be
used.
IMPORTANT!
The inverter can be used with max. an
automatic circuit breaker C 32 A.
