Conguring the DC plug connector
NOTE: Before proceeding with the isolation ensure that you don't cut any individual wires.
. Isolate wire for DC connection by mm.
. Insert isolated wire with twisted ends carefully up to the end stop.
NOTE: Wire ends must be visible in the spring.
. Close the spring so that the spring latches.
. Slide insert into sleeve.
. Tighten cable tting with the help of a mm fork wrench applying a torque of Nm.
. Join insert with contact plug.
. Check latch by lightly pulling on the coupling.
» Make the electrical connection.
NOTE
The permissible bending radius of at least x the cable diameter should be observed during installa-
tion. 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.
.. Checking the PV generator for a ground fault
DANGER
Danger to life from electric shock!
Severe injury or death will result if the live connections are touched. When there is solar radiation, DC
voltage will be present at the open ends of the DC cables.
› Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
› Avoid short circuits.
› Do not connect any strings with a ground fault to the unit.
