Creating Equipotential Bonding - Kaco blueplanet 87.0 TL3 Betriebsanleitung

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 mounting bracket 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.
8 Affix shrink tubing (not included as standard) over the shaft of the ring cable lug
of the DC cable.
9 Secure the DC mounting 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 cable fittings [ W_46 /

NOTE
Depending on the local installation specifications, it may be necessary to earth the device with a second
ground connection. To this end, the threaded bolt on the underside of the device can be used.

When using aluminium cable lugs we recommend using cable lugs with galvanic tin-plating or alternatively, AL/CU ca-
ble 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).
