3.1 Connecting 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.
3.1.1 Attaching Leak Detection Connection Cable to the Panel
To attach a leak detection connection cable:
1. Disconnect electrical power to the Liqui-tect
panel.
2. Locate the Zone 1 and Zone 2 cable connectors
on the controller board. They can be found on
the lower right corner of the board (see 1.4 -
Controller Board Overview). The Zone 1
connector is Cable 1 or TB9. The Zone 2
connector (Cable 2 or TB6) is just above it.
3. If necessary, remove a conduit knockout to
permit wire entry into the Liqui-tect panel
enclosure.
4. Bring the white connection cable
(CONNECT10) into the Liqui-tect panel
enclosure through a conduit knockout or
access slot.
5. Loosen a screw on the terminal block and slip
the stripped end of the appropriate wire into
the terminal block according to the color-coded
wiring key (see illustration at right).
Note that the WHITE wire connects to the “Y”
slot. The red wire connects to the “R” slot, the
green wire connects to the “G” slot and the black wire to the “B” slot.
6. Tighten the screw until it holds the wire snugly.
7. Repeat for each of the four wire strands in the connection cable.
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.
