5. Connect the insulated conductors to the Relay1 or Relay2 terminals using the 3-pole terminal
(torque: 0.5 Nm to 0.6 Nm):
7.5.6 Connecting BatVtgOut, DigIn, BatTMP, and BatCur
Always connect the cables to connections BatVtgOut, DigIn, BatTMP, and BatCur as follows.
Additionally required material (not included in the scope of delivery):
☐ Suitable bootlace ferrules if using stranded wire
Cable requirements:
☐ Copper wire
☐ Conductor cross-section: 0.2 mm² to 2.5 mm²
Procedure:
1. Break through a suitable location in the cable feed-through plate with a sharp object.
2. Strip the cable insulation.
3. For stranded wires: press the bootlace ferrules onto the insulated conductors.
4. Lead the conductors through the hole in the cable feed-through plate into the Sunny Island.
5. Connect the insulated conductors to the 4-pole terminal (torque: 0.5 Nm to 0.6 Nm).

Danger to life from electric shock due to incorrect insulation
High voltage can be present in the control cable. Faulty insulation can result in a conductive connection with other
cables or components. Live components can be touched due to this connection. Touching can result in death or
serious injury due to electric shock.
• Cut the silicon tube to the length of the cable in the Sunny Island.
• Pull the silicone tube over the cable.
☑ The cable is double-insulated.
• Lead the cable into the Sunny Island making sure that it does not touch any data cables.
