Explanation
The DC proportion of the feed-in current
is outside the permissible limit values.
A communication error has occurred in
the internal data transmission.
On account of a measured value that lies
outside the permissible range, a shut-
down has been performed to protect the
device Possible reasons for shutdown:
- Grid overvoltage (each phase is moni-
tored)
- Intermediate circuit overvoltage
- Intermediate circuit asymmetrical
- Grid current (each phase is monitored)
- internal reference voltage
Group message for all trip zone shut-
downs.
No valid version of the power unit was
detected.
The voltage of the PV generators has ex-
ceeded the permissible maximum value
(limit values, see data sheet).
The limit value is country-dependent. This
is a legally required check of the network
supplier.

Remedy
When this is shown once, the system at-
tempts a recalibration.
When this is shown frequently or contin-
uously, contact Service.
Note: Because of the country-specific
specification (e.g., Italy), the limit values
for switching off are very low.
If an installation technician is on site, the
communication cable between the dis-
play board and the AC power unit should
be checked for secure fit or a conven-
tional CAT5 cable should be used for the
check.
Note: A high-temperature-proof cable is
prescribed for use in the device. Please
contact Service.
Does the fault only occur sporadically?
How is the device connected on the grid
end (heavily inductive grid (on the trans-
former itself))? -> If the system has its
own transformer, the short-circuit volt-
age of the transformer provides informa-
tion on the inductance of the grid for the
system (4% short-circuit voltage is a very
good value). SW from V3.14 also supports
8% and more. => update SW.
If the error is present continuously, it can
be assumed that there is a device fault ->
Contact service department
The error can be caused by poor connec-
tion/cabling on the AC side. Check all con-
nection terminals from the device
through to the grid connection. A fluctu-
ating or missing AC voltage can indicate
this connection problem.
Grid-related shutdown of the grid opera-
tor. The grid reconnects automatically.
Please wait...
Restart of the device attempted? (Discon-
nect AC/DC - switch it back on after 5
minutes.)
=> If unsuccessful, contact Service.
Are the PV-strings connected in series in-
stead of in parallel? => Check PV voltage
with suitable measuring device and check
planning and assignment.
Your solar installer must check the AC
voltage at the terminals and AC wiring.
If the settings in the menu are also cor-
rect, contact Service.
