§
NOTE! A residual current circuit breaker for the AC connecting cable may be re-
quired depending on local regulations, the power supply company, and other con-
ditions. A type A residual current circuit breaker with a trip current of at least
100 mA is generally sufficient in this case. However, false alarms can be triggered
for the residual 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.
