Fronius Symo Hybrid 3.0, Installation Instructions Manual, Page: 5 / 40

CAUTION!
Danger due to poor or unprofessional installation.
This may result in damage to inverters and other live photovoltaic system components.
Poor or unprofessional installation can cause overheating of cables and terminal connec-
tions and result in arcs. These can cause heat damage, which in turn may lead to fires.
Observe the following when connecting AC and DC cables:
▶
Tighten all terminals to the torque specified in the Operating Instructions
▶
Tighten all grounding terminals (PE / GND), including free ones, to the torque spe-
cified in the Operating Instructions
▶
Do not overload cables
▶
Check cables for damage and verify that they are laid correctly
▶
Take note of the safety instructions, Operating Instructions and any local connection
regulations
▶
Using fastening screws, always screw the inverter firmly to the mounting bracket to
the torque specified in the Operating Instructions.
▶
Ensure that the fastening screws are tight before starting the inverter!
Note! Fronius will not accept any costs associated with production downtimes, installer
costs, etc., that may arise as the result of a detected arc and its consequences. Fronius
accepts no liability for fires that can occur despite the presence of the integrated arc
detection/extinguishing system (e.g. fires caused by a parallel arc).
Note! After an arc has been detected, the entire photovoltaic system must be checked
for possible damage before resetting the inverter.
Observe the manufacturer's connection, installation and operating instructions at all
times. To reduce the hazard potential to a minimum, perform all installation and connec-
tion work carefully according to the instructions and regulations.
Refer to the device Operating Instructions / Installation Instructions for the tightening
torques to be used at the relevant terminal connections.
Proper use The solar inverter is exclusively intended for charging a battery with direct current from
solar modules, or for converting this direct current into alternating current and feeding it
into the public grid or the household network in emergency power mode.
The following actions constitute improper use:
-
Any use above and beyond this purpose
- Making any modifications to the inverter that have not been expressly approved by
Fronius
- Installing components that are not distributed or expressly approved by Fronius
- Operating the device with a battery that has not been approved by Fronius
- Operating the equipment with an energy meter that has not been approved by
Fronius
Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.
Proper use also includes:
-
Carefully studying and obeying the Installation and Operating Instructions
- Performing all stipulated inspection and maintenance work
When designing the photovoltaic system, ensure that all of its components are operated
within their permitted operating ranges at all times.
Observe all the measures recommended by the solar module manufacturer to ensure
that the solar module retains its properties in the long term.
