The Products must be connected to an external device as per the connection diagrams (see Appendix G).

Two LLS 20230 fuel level sensors can be connected to one BIS 20240 spark protection unit with the KTZ splitter and two KTZ cables (Figure 41), provided that BIS 20240 voltage is at least 12 V (when connecting BIS 20240 to the on-board power supply, FTC AVL unit, or third-party AVL unit).

When connecting the BIS 20240 spark protection unit to the battery, the BR15 galvanic insulation unit (Figure 42) must be used.
