Connecting BatVtgOut, DigIn, BatTMP and BatCur
Qualified person
Always connect the cables to connections BatVtgOut, DigIn, BatTMP and BatCur as follows.
Information on the connection BatVtgOut
The entire DC voltage range of the connections DC+ and DC- is mapped at the connection BatVtgOut.
The connection BatVtgOut is current-limited and protected against short circuit.
Additionally required material (not included in the scope of delivery):
- Suitable bootlace ferrules if using stranded wire
Requirements:
Conductor cross-section: 0.2 mm² to 2.5 mm²
Cable length for BatCur: less than 3 m
Cable length for BatVtgOut, DigIn, and BatTemp: less than 30 m
If cable lengths of 30 m and more are required for BatVtgOut, DigIn, and BatTemp, suitable lightning protection precautions must be taken.
If the battery temperature sensor and the batteries are not installed with the inverter in the same building, suitable lightning protection precautions must also be taken.
Procedure:
- Break through a suitable location in the cable feed-through plate with a sharp object.
- Strip 7 mm of the cable insulation.
- Lead the insulated conductors through the hole in the cable feed-through plate into the Sunny Island.
- Thread the cable for the connections BatVtgOut and DigIn through a ferrite included in the scope of delivery.
- Thread the cable for the connections BatTmp and BatCur through a ferrite included in the scope of delivery.
- Connect the insulated conductors to a 4-pole terminal block included in the scope of delivery (torque: 0.5 Nm to 0.6 Nm, blade width: 1 mm):
- Ensure that the conductors are plugged completely into the terminals up to the insulation.
- In accordance with the labeling, plug the 4-pole terminal block into the connection on the inverter until the terminal block audibly snaps into place.
