Fronius Primo 10.0-1 Instructions D'installation page 6

NOTE!
- Make sure that the grid neutral conductor is grounded. For IT networks (isolated networks without
grounding), this is not the case, and operation of the inverter is not possible.
- To use the inverter, a neutral conductor connector is required (depending on grid configuration,
see page 24).
The infeed of the inverter can be adversely affected by a neutral conductor with small dimensions.
Therefore, the neutral conductor must have the same dimensions as the other current-bearing
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 unused
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 wall
bracket to the torque specified in the operating instructions.
Ensure that the fastening screws are tight before starting the inver-
ter!
Manufacturer's instructions regarding connection, installation and operation must always be observed. To re-
duce 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.
