Connecting solar modules
Only solar modules of the following category may be connected: Class A as specified in IEC 61730.
The PV generators may only be connected to the inverter when this is voltage-free.
DANGER
Risk of death due to electrical shock and discharge!
The PV generators/cables may be live as soon as they are exposed to light.
- De-energise the inverter.
DANGER
Risk of death due to electrical shock and discharge!
De-energise device and secure against being switched on again. De-energising the inverter
- If there is more than one inverter in a PV system, ensure that no cross-connection occurs when the PV generators are connected.
INFO
Damage possible
If the PV generators are incorrectly connected (including cross-connection on the inverter itself), the inverter may be damaged. Check the connections before commissioning.
- Check the strings for earth faults and short circuits and rectify these where appropriate.
- Correctly fit the plug on the positive cable and the socket on the negative cable. The inverter is equipped with plug connectors from PHOENIX CONTACT (type SUNCLIX). During installation, always observe the most recent specifications from the manufacturer (e.g. use of special tools, permissible tightening torques etc.).
Information on the SUNCLIX installation instructions can be found at: www.phoenixcontact.com - When mounting the sockets and plugs on the DC cables used by the solar modules, ensure their polarity is correct! The poles of the PV strings (PV field) must not be earthed.
IMPORTANT INFORMATION
Use flexible and tin-plated cables with double insulation according to EN 50618.
We recommend a cross-section of 6mm². Please observe the specifications of the plug manufacturer and the technical data for the inverter.
- Plug the sockets and plugs of the DC cables onto the inverter. Retain the plug seals from the plug connectors.
IMPORTANT INFORMATION
The solar module types used and the orientation in one PV string should be the same.
- The DC side is connected.
