signals may be attenuated or amplified by the inverter. The settings below can be
used to counteract this if necessary.

"Reduction of
Influence"
Off The function is deactivated.
On The function is activated.
"Frequency of

Signal"
100 ‑ 3000 Hz The frequency specified by the energy
company must be entered here.
"Grid Induct-
ance"

5 H
The value measured at the feed-in point
must be entered here.
"Measure against RCD false triggers"
(when using a 30 mA residual current circuit breaker)
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.
Nevertheless, 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 recommends that a residual current
circuit breaker with a tripping current of at least 100 mA suitable for frequency
converters be used.
Parameter Range of val-
ues
Description
"Switch-Off be-
fore 30mA RCD
Trip" (only for
Primo GEN24)
0 No measures to prevent false tripping.
1 The inverter switches off at 15 mA before
the residual current circuit breaker trips.
"Leakage Cur-
rent Factor"
(only for Symo
GEN24)
0 ‑ 0.25
(default: 0.16)
Reducing the setting value reduces the
leakage current and raises the intermedi-
ate circuit voltage, which slightly reduces
the efficiency. Setting value 0.16 enables
optimum efficiency.
"Iso Warning"
Parameter Range of val-
ues
Description
"Iso Warning" Off The isolation warning is deactivated.
On The isolation warning is activated.
A warning is issued in the event of an isola-
tion fault.
