Phase Configuration

Three Phase Connection—Factory Default

Just below the twelve load breakers there are three Fast-On termination blocks, one each for the X, Y
and Z phases. The unit is factory wired for three phase operation, with the twelve load circuits evenly
distributed, four to each phase. There will be four black wires on the X phase termination block, four reds
on the Y, and four blues on the Z for three phase operation.

Single Phase Connection—User Configured

If single-phase operation is desired, the four blue Z phase load wires must be re-connected to the X and
Y phase blocks. Detach the two blue-with-black-tape wires and move them to the two open position on
the X phase termination block. Move the two blue-with-red-tape wires to the Y phase block.

The system will automatically sense the phase configuration and adjust the dimmer timing accordingly.

Once terminated, the power inlet terminal blocks are to be torqued to 45 inch/lbs.

Load Connections

Load connections must enter at the top of the LWD-2400. The installer must punch the panel as required.

Connect the 12 NEUTRUAL wires to the NEUTRAL bus bar. A second bus bar is provided for the 12
GROUND wires. Finally, as shown in the figure, LOAD 1 through LOAD 6 are connected to the six
position terminal strip to left of center, and LOAD 7 through LOAD 12 on the right.

Once terminated, load terminals are to be torqued to 12 inch/lbs.

DMX Connections

A terminal strip is supplied for connection to the DMX control cable. Figure 2 shows the location and
connections required on this block. Two connections can be made to the block for daisy chain connection
to other dimmers in the system.

It is important that the proper type of cable is used for DMX connection. If you have questions about
suitable cable types, contact a Leprecon dealer or refer to the USITT specification for DMX 512.
Suggested cable types include Belden 9841 and Belden 9842. Microphone cable is not acceptable for
use as DMX communication cable.

For convenience in programming and testing, a DMX-in XLR connector is provided at the bottom panel of
the dimmer.

Panel Communications Connections

LWD dimmers connected to Architectural panels form a networked system. If networking of two or more
LWD-2400’s is desired, the Communication terminal strip is used. The four external communications
wires must be attached to the COMM terminal strip as shown in the figure.

The figure lists the color of the wires as GRN, RED, BLK and YEL. Actual color is unimportant, but proper
connections are. Be sure that the wires 1 through 4 are connected to pins 1 through 4 of every unit in the
system.
