NOTE! For grounding solar module frames or racks, the relevant specifications from the solar module 
manufacturer must be taken into account along with national guidelines.
NOTE! Observe the ESD guidelines when using option cards.
NOTE! If the inverter is installed in Australia or New Zealand (required standard: AS4777.2:2015), the 
inverter must not be used as part of a three-phase combination, as there is no communication link 
between the inverters
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 re-
sult 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 Ope-
rating 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!
Observe the manufacturer's connection, Installation and Operating Instructions at all times. To reduce the ha-
zard 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.
