1 | General information
Preparing the connection of the PV generator
↻ PV generator checked for a ground fault.
↻ Connection cables with 2 x 1 or 2 x 2 strands already on the device.
1. For improved accessibility: Unfasten the DC input plate using the 4 screws [
T_30].
2. Unfasten the cable fitting for the DC connection [ W_46]
3. Remove the sealing plug in the cable fitting used.
4. Remove the outer cladding of the DC cables.
5. Guide the DC leads through the cable fittings.
6. Strip the insulation from DC cables according to M10 ring cable lug so that the
strand and insulation can be pressed into the cable lug shaft.
. CAUTION! Risk of fire due to chemical corrosion. Cable lugs must be
suitable for the conductor material and copper busbars being used
7. Press ring cable lug onto DC wires. When crimping, ensure that the ring cable
lug is rotated in accordance with the final installation position.
. CAUTION! Danger to life due to a surge in voltage. If the clearance is
insufficient, shrink tubing (>= 6 kV/mm dielectric strength) must be
used.
8. Guide the shrink tubing over the uninsulated crimping point and a maximum of
+0/-2
20 mm over the cable insulation and shrink-fit using manual shrink-fitting
equipment. However, the shrink tubing must not protrude into the seal of the
cable fitting.
9. Secure the input plate using the 4 screws [ T_30 /
10.Connect the PV generator.
Connecting the PV generator
↻ PV generator connection prepared.
↻ DC cables equipped with a ring cable lug [max width 42 mm ].
1. Place the cable lug of cores DC- and DC+ on the busbar in accordance with the
labeling and secure it with a nut, screw and lock washer (fastening elements in
scope of supply) [ W_17 /
2. Check that the connected cables are fitted securely.
3. Tighten the cable fittings [ W_46 /
ð The device is connected to the PV generator.

When using aluminium cable lugs we recommend using cable lugs with galvanic tin-plating or alternatively, AL/CU
cable lugs as well as appropriate AL/CU washers.
Otherwise, the aluminium may be destroyed by the copper busbars in the presence of electrolytes (e.g. condensate).
