Fire Prevention - Fronius Symo Serie Instrucciones De Instalación

NOTE! When photovoltaic modules are exposed to light they supply current to the inverter.
NOTE!
- Ensure that the grid neutral conductor is grounded. This may not be the case for IT grids (insulated
grids with no grounding); it will then not be possible to use the inverter.
- In order to use the inverter, the neutral conductor must be connected.
A neutral conductor that is too small may adversely affect the grid power feed operation of the in-
verter. The neutral conductor must therefore be the same size as the other live conductors.

Fire prevention

CAUTION! Risk of damage to inverters and other live photovoltaic system components due to poor or
unprofessional installation.
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 Instruc-
tions.
Ensure that the fastening screws are tight before starting the inver-
ter!
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 Operating Instructions / Installation Instructions for the tightening torques to be used at the
relevant terminal connections.
