↻ Connection area opened.
↻ NOTE:Before proceeding with the isolation ensure that you do not cut any individual wires.
1. Strip the wires for DC connection [sl ].
2. Insert isolated wires with twisted ends carefully up to the connection.
. NOTE:Wire ends must be visible in the spring.
3. Close the spring so that the spring latches.
4. Slide insert into sleeve.
5. Secure and tighten the cover on the cable fitting [ W_15/ 1.8 Nm]
6. Join insert with contact plug.
7. Check latch by lightly pulling on the coupling.
ð Make the electrical connections.
NOTE
The permissible bending radius of at least 4x the cable diameter should be observed during install-
ation. Excessive bending force may negatively impact the protection rating.
1. All mechanical loads must be absorbed in front of the plug connection.
2. Rigid adaptations are not permitted on DC plug connectors.
