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

To attach a leak detection connection cable:

1. Disconnect electrical power to the Liqui-tect

panel.			Leak Detection Cable
2. Locate the Zone 1 and Zone 2 cable connectors		R
			Terminal Blocks:
on the controller board. They can be found on		G
			Zone 2
the lower right corner of the board (see 1.4 -
		B	Zone 1
Controller Board Overview). The Zone 1
connector is Cable 1 or TB9. The Zone 2		Y
connector (Cable 2 or TB6) is just above it.	TB6
3. If necessary, remove a conduit knockout to
permit wire entry into the Liqui-tect panel
enclosure.	X6		WIRING
4. Bring the white connection cable	Cable 1		CONNECTIONS
(CONNECT10) into the Liqui-tect panel		R	Red Wire
enclosure through a conduit knockout or
access slot.		G	Green Wire
5. Loosen a screw on the terminal block and slip		B	Black Wire
the stripped end of the appropriate wire into
		Y	WHITE Wire
the terminal block according to the color-coded

wiring key (see illustration at right). TB9

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.
