The DC connection is intended exclusively for PV generators. Other sources fall within the scope of improper operation
(e.g. batteries).
4.4.1 Connecting the PV generator
↻ PV generator checked to ensure there is no ground fault.
↻ A DC cable with 2 x 1 or 2 x 2 cores is available on the device.
↻ DC polarity checked before connection made to device.
1 Activate the connection power at the switchbox or string combiner with the DC
isolator switch.
2 For improved accessibility: Secure the DC input plate using the 4 screws [
T_30].
3 Undo the cable fitting for DC connection [
4 Remove the sealing plug in the cable fitting used.
5 Remove the outer cladding of the DC cables and insert them through the cable
fitting.
6 Strip the insulation from the DC cables pursuant to the M10 ring cable lug so
that the stranded wire and insulation can be pushed into the shaft of the cable
lug.
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. [See figure 6] [} Page 6]
7 Push the ring cable lug onto DC cores. When crimping, ensure that the ring ca-
ble lug is rotated in accordance with the final installation position.
CAUTION! Use a shrink tubing (>= 6 kV/mm dielectric strength), as the clear-
ance is insufficient. This prevents a surge in voltage.
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.
9 For improved accessibility: Secure the input plate using the 4 screws [
T_30 / / 53.10 In-Ibs ]
ð DC cable configured. Continue with the connection to the DC filter or
DC switch.
Connecting the DC cable to the DC filter
↻ DC cables equipped with a ring cable lug [max width 1,65 inch ].
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 [
» The device is connected to the PV generator.
