Connecting the PV generator to the device

7.5.1 Configuring the DC connector
DANGER
Risk of fatal injury due to electric shock!
Coming into contact with live connections can cause serious injury or death. When there is sunlight present
on the PV generator, there is DC voltage on the open ends of the DC cables.
› Make sure that PV modules have good insulation against ground.
› On the coldest day based on statistical records, the max. open-circuit voltage of the PV modules must
not exceed the max. input voltage of the inverter.
› Check the polarity of DC cables.
› Ensure that the device is completely free of DC voltage.
› Do not disconnect DC connectors under load.

 NOTE: Before proceeding with the isolation ensure that you do not cut any individual wires.
1. Insert isolated wires with twisted ends carefully up to the connection.
NOTE: Wire ends must be visible in the spring.
2. Close the spring so that the spring latches and slide insert into sleeve.
3. Secure and tighten the cable fitting [
4. Join insert with contact plug.

5. Check latch by lightly pulling on the coupling.
Make the electrical connections
NOTE
The permissible bending radius of at least 4x the cable diameter should be observed during installation.
Excessive bending force may negatively impact the protection rating.
› All mechanical loads must be absorbed in front of the plug connection.
› Rigid adaptations are not permitted on DC plug connectors.
