3-3.1 Power via Wall Adapter
The LDZ4 can be powered by a wall adapter. Before connecting the wall adapter to the LDZ4, 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 24VAC/VDC receptacle located at P1. Plug the
other end of the adapter into the wall. The LDZ4 should power up immediately.
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 TB8. The minus, or ground, wire is placed into the center opening in the
terminal block. The plus, or live, wire is placed into the right opening in the terminal block. The left
opening of the terminal block will be empty. A separate Earth ground line can be placed in this opening.
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 LDZ4 should power up immediately.
3-3.2 Power via Direct Line
Once the power is turned off, strip the end of the 24VAC/VDC supply so the three wires inside are
exposed. Strip the end of each of the three wires and feed the end of the power supply into the LDZ4
enclosure. The three wires must now be inserted into the terminal block in the lower right corner of the
enclosure. As is labeled in the enclosure, the Earth ground line is placed into the left hand opening of the
terminal block. The minus, or ground, line is placed into the opening in the center of the terminal block.
The plus, or live, power line is placed inside the right hand opening of 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. Turn the 24VAC/VDC supply back on. The
LDZ4 should power up immediately.
