Parameter Value range Description
"Inverter shut-
down before 30
mA FI triggers"
0 No measures to prevent false alarms.
1 The inverter shuts down at 15 mA, before
the residual current circuit breaker is
triggered.
"Leakage cur-
rent factor for
reducing
RCMU/FI false
alarms"
0 ‑ 0.25
(default: 0.16)
By reducing the set value, the leakage cur-
rent is reduced and the intermediate cir-
cuit voltage is increased, which slightly
lowers the efficiency. A set value of 0.16
ensures optimum efficiency.
"Insulation warning"
Parameter Value range Description
"Insulation
warning"
Off The insulation warning is deactivated.
On The insulation warning is activated.
A warning is output in the event of an insu-
lation fault.
"Insulation
measurement
mode"
Exact Insulation monitoring takes place with the
highest degree of accuracy and the meas-
ured insulation resistance is displayed on
the user interface of the inverter.
Fast Insulation monitoring takes place with a
lesser degree of accuracy, whereby the
time to take the insulation measurement is
shortened and the insulation value is not
displayed on the user interface of the in-
verter.
"Threshold for
the insulation
warning"
100000 ‑
10000000 Ω
If the value drops below the threshold,
status code 1083 is displayed on the user
interface of the inverter.
"Backup power"
Parameter Value range Description
"Backup power
nominal
voltage"
220 ‑ 240 V The nominal phase voltage that is output
in backup power mode.
"Backup power
undervoltage
protection limit
value U< [pu]"
0 ‑ 2 % V This set value represents the limit value
for shutting down backup power mode.
e. g., set value 0.9 = 90 % of the nominal
voltage.
"Backup power
undervoltage
protection time
U<"
0.04 ‑ 20 s Trip time for falling below the backup
power undervoltage protection limit value.
"Backup power
surge protec-
tion limit value
U> [pu]"
0 ‑ 2 % V This set value represents the limit value
for shutting down backup power mode.
e. g., set value 1.1 = 110 % of the nominal
voltage.
"Backup power
surge protec-
tion time U>"
0.04 ‑ 20 s Trip time for exceeding the backup power
surge protection limit value.
