Creating Equipotential Bonding - Kaco blueplanet 87.0 TL3 Betriebsanleitung

Operating Instruction I
Connection PV generator with DC switch
↻ DC cables inserted through the input plate.
↻ CAUTION! Risk of fire due to chemical corrosion. Cable lugs must be
suitable for the conductor material and copper busbars being used
↻ WARNING! Risk of short circuit due to incorrect size of the cable lug!
Observe the dimensions for the selection. [Fig. 21: Configuring the DC
cable [}[21]
1. Fit the DC cables with a ring cable lug. When crimping, ensure that the ring
cable lug is rotated in accordance with the final installation position. [Fig. 22:
Fit DC cables to switch [}[21]
. WARNING! Danger to life due to a surge in voltage. If the clearance
is insufficient, shrink tubing (>= 6 kV/mm dielectric strength) must
be used.
2. 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.
3. Draw in cables to the indicated fixing length and run with cable fitting.
ð DC cable configured. Continue with the connection to DC switch.
↻ DC cable is configured.
↻ DC input plate pulled back from the connection side. [approx. 20 cm]
. NOTE: For installation of the DC cables, use a torque wrench as well
as the included open-ended wrench for counter-resistance.
1. Pre-fit DC cable pair with the pre-installed screw and counternut onto the DC+
and DC busbar of the DC switch.
2. Option for 2 cable pairs: Insert spacer sleeve between 2 DC cables and pre-as-
semble in pairs with the provided screws and counternuts onto the DC+ and DC
busbar of the DC switch.
3. Slide the DC input plate up onto the housing base and secure. [ T_30 /
Nm]
4. Secure the screws and counternuts onto the DC+ and DC busbar of the DC
switch. [ W_16/17] /
5. Tighten the cable screw fitting. [ W_46 /
ð Component is electrically connected. Continue with the installation in the in-
verter.

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
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).
