Fire Prevention EN
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

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
