Fire prevention
CAUTION!
Danger due to poor or unprofessional installation.
This may result in damage to inverters and other live photovoltaic system com-
ponents.
Poor or unprofessional installation can cause overheating of cables and terminal
connections 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
specified 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 con-
sequences. Fronius accepts no liability for fires that can occur despite the pres-
ence 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 connection work carefully according to the instructions and regulations.
Refer to the device Installation Instructions for the tightening torques to be used
at the relevant terminal connections.
Proper use The inverter is designed to be connected and used exclusively in conjunction with
ungrounded solar modules. The solar modules must not be grounded at either
the positive or negative pole.
The solar inverter is intended exclusively to convert direct current from solar
modules into alternating current and to feed this into the public grid.
Utilisation not in accordance with the intended purpose comprises:
-
any use above and beyond this purpose
-
making any modifications to the inverter that have not been expressly ap-
proved by Fronius
-
the installation of components that are not distributed or expressly ap-
proved by Fronius.
Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.
