Text of the Warning Notices:
WARNING!
Risk of electric shock!
Non-insulated inverter
Do not remove the cover. The device does not contain any user-serviceable parts. Main-
tenance work must be carried out by a trained service technician.
Both AC and DC voltage sources terminate inside this device. Each circuit must be turned
off before carrying out maintenance work.
Wenn das Solarmodul-Feld Licht ausgesetzt wird, liefert dieses eine Gleichspannung an
dieses Gerät.
Gefahr eines elektrischen Schlages durch in Kondensatoren gespeicherte Energie. Deckel
nicht entfernen, bevor nach Abschalten aller Versorgungsquellen 5 Minuten vergangen
sind.
Ungeerdetes System: Die DC Leitungen dieses Photovoltaiksystems sind nicht geerdet
und können stromführend sein.

String Fuses

Only applies to device type Fronius Symo 15.0-3 208 and device types Fronius Symo
15.0-3 480 / 20.0-3 480 / 22.7-3 480 / 24.0-3 480 with the "Ecofuse" option:
The use of string fuses in the Fronius Symo provides additional fuse protection for solar
modules.
The maximum short circuit current I
specification of the maximum string fuse value in the module data sheet of the respective
solar module are decisive factors in the protection of the solar module.
The maximum short circuit current I
The string fuse release current can be set to greater than 15 A if required.
If the inverter is being operated with an external string collection box, the DC connector kit
(item numbers 42,0201,4479 and 42,0201,4480) must be used. In this case the solar mod-
ules are externally protected in the string collection box and the metal bolts should be used
in the inverter.
National regulations regarding fuse protection must be observed. The electrician perform-
ing the installation is responsible for choosing the right string fuses.
