3-3 APPLY POWER TO THE UNIT
Once cable for all the desired leak detection zones has been connected to the unit, power may be applied.
The LDRA6 operates on 24VDC power supplied by a wall adapter or a direct line. A power supply should
be run to the location of the unit.
3-3.1 Power via Wall Adapter
The LDRA6 can be powered by a wall adapter. Before connecting the wall adapter to the LDRA6, unplug
the adapter from the wall. If the adapter has a connector on the end, feed the cord through one of the
knockouts in the enclosure and plug it directly into the 24VDC receptacle located at POW1. Plug the other
end of the adapter into the wall. The LDRA6 should power up immediately.
3-3.2 Power via Direct Line
If the adapter does not have a connector on the end, strip the end of the adapter line so the two wires inside
are exposed. Strip the end of each of the two wires and feed them into the enclosure. Insert the two wires
into the terminal block labeled TB1. The minus, or ground, wire is placed into the right opening in the
terminal block. The plus, or live, wire is placed into the left opening in the terminal block.
Once all the wires have been placed inside the terminal block, tighten the three screws across the bottom of
the terminal block until the wires are securely held in place. Plug the other end of the wall adapter into the
wall. The LDRA6 should power up immediately.
