1.6.3 Configuring the DC connection
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 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 there is no DC voltage present.
› 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.

Making the electrical connection
Connecting the PV generator
DC plug connector has to be configured and PV generator checked to ensure there is no ground fault.

NOTE: Note the different current-carrying capacity of PV1, PV2 and PV3 depending on the power class
of the device. See max. input current in the data sheet as well as in the complete manual.
1 Remove protective caps from the required DC connection plugs on the underside of the device.
»
2 Connect the DC plug connectors to the DC positive and DC negative connectors in pairs (see fig. 8.2).
The device is connected to the PV generator.
