2.1.9 TB7: Cable Interface

The SeaHawk Water Leak Detection Cable (SC) connects to TB7. A 15 foot (4.57m) non-

sensing leader cable (part # LC-KIT) is required to connect the LD5100 to the SC cable.

Connect the cable wires to TB7 as follows:

TB7-1 White wire

TB7-2 Black wire

TB7-3 Green wire

TB7-4 Red wire
