Connections and Configuration

3.1Connecting Leak Detection Cable Inputs

The leak detection cable inputs are found on the lower right side of the Liqui-tect panel’s printed wir- ing assembly board. There are two terminal blocks for the inputs; the lower terminal block is for the Zone 1 cable and the terminal block above it is for a second leak detection cable, Zone 2.

To determine the proper wire size, see Table 4 - Wiring specifications.

NOTE

Each terminal block is a removable, two-part assembly to permit easier connection of more than one input at a time. If making multiple connections, grasp the upper portion of a block and pull firmly to the right until the assembly pulls apart.

After making the connections, push the removed piece back into the portion attached to the printed wiring assembly until the terminal block pieces lock together.

3.1.1Attaching Leak Detection Connection Cable to the Panel
