§
NOTE! A residual current circuit breaker for the AC connecting cable may be re-
quired depending on local regulations, the grid operator, and other conditions. A
type A residual current circuit breaker with a trip current of at least 100 mA is gen-
erally sufficient in this case. However, false alarms can be triggered for the resid-
ual current circuit breaker type A in individual cases and depending on local
conditions. For this reason, Fronius recommends that you use a residual current
circuit breaker suitable for frequency converters.
If excessively long AC or DC cables are laid
in loops in the connection area, fix the cab-
les to the designated eyelets at the top and
bottom of the connection block using cable
ties.
