NOTE! If the cable insulation of the AC cable is not designed for a maximum of 1000 V, AC and DC
cables must not be crossed when connecting in the inverter.
If crossing the cables during connection is unavoidable, the AC cable must be laid in one piece of the
protective hose supplied with the inverter.
AC and DC cables can only be laid together if the insulation on both cables is designed for the max.
possible voltage of 1000 V.
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.
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 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 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.
