Connect protective conductor
First, connect the protective conductor of the DC cable to the grounding connector:
1. Remove the sheath of the cable to connect the cable lug.
2. Choose a cable lug for the appropriate conductor cross section.
3. Strip the insulation from the end of the conductor so that the remaining insulation extends up to the cable lug.
4. Fasten the cable lug correctly to the end of the conductor.
5. Insert the cable lug into the grounding connection.
6. Tighten the nut at the grounding connection with a tightening torque of 45 Nm.
7. Check the connection between the PE conductor and the grounding connection.
8. Apply sealing paint.
Connecting the DC+/DC- conductors
Connect the DC+/DC- conductors of the DC cable to the DC busbars:
1. Remove the sheath of the cable to connect the cable lug.
2. Choose a cable lug for the appropriate conductor cross section.
3. Strip the insulation from the end of the conductor so that the remaining insulation extends
up to the cable lug.
4. Fasten the cable lug correctly to the end of the conductor.
5. Insert a shrink-on sleeve over the cable lug. The shrink-on sleeve must extend slightly
beyond the insulation of the cable and cover the crimping point of the cable lug.
6. Use a suitable tool to heat the shrink-on sleeve.
7. Plug the DC+ cable lug onto the DC+ busbar.
8. Tighten the screw with the DC+ cable lug with a tightening torque of 45 Nm.
9. Insert the DC- cable lug onto the DC- busbar.
10. Tighten the screw with the DC cable lug with a tightening torque of 45 Nm.
11. Verify that the DC conductor is connected to the DC terminals.
12. Apply sealing paint.
Connection of additional SICHARGE UC dispensers
The DC connector and the PE are looped through to connect additional SICHARGE UC dispensers to the
same SICHARGE UC charging station. This is shown as item f in the "DC cable connection" figure. To do
this, follow the above sequence to connect the DC cable and the PE conductor.
Never install the two conductors on one side of the copper busbar. Mount one conductor on the top of
the busbar and the other on the bottom of the respective DC busbar. For the PE conductor, mount one
conductor on the right and the other on the left side of the PE connector.
