Connecting the protective conductor
First, connect the protective conductor of the DC cable to the ground connection:
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 ground connection.
6. Tighten the nut at the grounding connection with a tightening torque of 45 Nm.
7. Check the connection between the protective conductor and the ground 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 Dispenser
The DC connector and the PE are looped through to connect additional
SICHARGE UC Dispenser to the same SICHARGE UC charging station. This is shown as item
in the "DC cable connection" figure. To do this, follow the above sequence to connect the DC
cable and the protective 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. At the
protective conductor, mount one conductor on the right and the other on the left side of the
protective conductor connection.
