injury and property damage.
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.
Maintenance 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.
If the solar module is exposed to light, it will supply a DC voltage to the device.
Risk of electric shock due to energy stored in capacitors. Do not remove the cov-
er until all power supply sources have been switched off for at least 5 minutes.
Ungrounded system: The DC cables in this PV system are not grounded and can
be live.
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" op-
tion:
The use of string fuses in the Fronius Symo provides additional fuse protection
for solar modules.
The maximum short circuit current I
I and the specification of the maximum string fuse value in the module data
R
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.
However, a release current of 20 A must not be exceeded.
