SMA Solar Technology AG Electrical Connection
Technical Description SI5048-TEN093630 39
For connection, proceed as follows:
1. Poke through the appropriate place in the cable insert with a pointed object.
2. Starting from the outside, feed the cable with cable end sleeves through the hole in the
Sunny Island.
3. Connect the cables correspondingly to the "BatTmp" connection of the 4-pole print terminal
included in the delivery.
4. Tighten the terminals.
5. Insert the 4-pole print terminal into the "BatTmp" socket on the Sunny Island.
6. Attach the battery temperature sensor externally to one of the battery cells. Choose a spot
between two cells or as close as possible to such a spot. This place should be in the middle area
of the battery tank, because that is where heat generation is greatest during operation.
Polarity of the cables
The polarity of the two cables is irrelevant for the functioning of the battery temperature
sensor.
