Electrical Trim

After the sheetrock goes up it is time to connect all of the lights and switches to the wire you ran in the previous step. All of our connectors are easy to install and require only a few basic tools. In this step it becomes much more important to have labels on your wire as you can no longer see which wires control which sets of lights. 

DR2 Switches

To connect power to the switch, strip about a quarter of an inch of the red and black power wires and insert them into one of the bottom connectors on the switch. The black wire goes to the negative side and the red to the positive.

The DALI connections use the CAT5 data wire run in parallel with the power line and are located on the right side of the switch. The top four terminals are used for DALI data and the bottom two to enable a physical two-way switch. We suggest using the brown wires for DALI and using the blue wires for two way switching. To connect a light switch to the DALI bus, strip a quarter inch of the brown wires and insert them into the the paired connections marked DA.

If you are connecting a three-way switch you’ll need to run a length of CAT5 wire to connect the two switches. The two switches should be connected through the NWAY and GND terminals on the DR2. We suggest connecting the solid blue to NWAY and the striped blue to GND. The other switch should be a simple single throw single pole switch. More information on 3-way switch can be found in this guide.

If you’ll be daisy chaining the switch to connect other switches together you’ll need to run DALI and power from one switch to the next. To connect DALI data, insert your brown CAT5 wires from the bottom DA inputs to the top two DA inputs on the next switch. The power wires should run in parallel to the data lines from the unused power input on the switch to the power input on the second switch. The three wings on either side of the face plate will also need to be broken off using pliers. 

The last piece to prepare is to set the output current. The switch is set to 300mA for each output by default. To increase the current, connect the two male header pins using a jumper. Connecting both raises the max current to 720mA. The output current needed depends on the current required of the lights being used. For the 4" wafer one jumper will be needed on the 60mA pins to increase the current to 360mA. If the DR2 is connected to a Doubler, you’ll need to set the output to 720mA.

 

Fixtures

How the lights get installed depends largely on how the wiring was finished, either a junction box or a service loop. If a junction box was used, the box needs to be removed before installing the light. If the service loop was used, pull the wire from the loop out of the hole drilled into the sheetrock where the light is to be placed.

Coming from the DR2 there should be two wires, a black and a red. If there is only one LED, connecting the wires is very straight forward. Strip a quarter inch of the black and red wires from the DR2 insert them into the OJ-606 connector, and plug it into the light. 

 

If there a multiple lights they need to be wired in series because they run on a constant current. The red power wire from the DR2 should be connected to the red power wire of the first LED. The black ground wire from that same LED should be connected to the red power wire of the next LED. The ground wire from the DR2 should be connected to the ground of the last light. If there are more than two lights in the string, continue running them in the same manner connecting the black ground wire to the red power wire of the next light. Once you reach the last light in the string, you simply need to connect the ground wires together all the way back to the ground terminal of the DR2.

Installing the light into the drywall is easy. Simply push the side springs up into the hole and then light should fit in perfectly. To remove the light simply pull the light down keeping your fingers clear of the springs.

To connect power to a fan, connect the power and ground from the switch to the fan. A fan should never be run in series with any other fixture.

LED Drivers/Tunable White

In a larger room it is likely that the lighting calls for an AL-WS-010V switch instead of the typical DR2. This means that you'll be using separate LED drivers for the lights. Up to sixteen 4" LEDs can be wire in a string. This keeps the wattage on a single run less than 100W.

 

There are two types of drivers: smaller drivers placed with the lights and larger drivers placed in the wiring panel. Using the smaller drivers means they can likely fit above the light. To wire the Mean Well LDD-350 (the driver we suggest) you need to supply power and a control line to each driver. To ensure they all get 48V they should all be wired in parallel. The 0-10V switch does not have 48V outputs so you will have to bring in 48V from the main panel using 16 AWG.

To start wiring the 010V switch, connect the DALI lines to the switch as usual using the brown pair from the CAT5 wire. The green pair will also be connected with the solid green connecting to the PWM output and the striped green to the GND output. Now all of the work on the switch is done.

At the wiring panel, terminate the CAT5 wire with an RJ45 connector and plug it into the panel. The panel is modified so there is a connection from the solid green DALI connection to the earth ground output changing it to a PWM output. The striped green connection has also been modified to tie into the ground of the power so the PWM has the same ground as the supply. To connect the string of meanwell drivers, plug the red wire into the positive terminal (right), the black wire into ground (middle), and the white driver control line into the PWM output (left).

To wire lights for tunable white the process is nearly identical to that of connecting a meanwell driver. The only difference on the switch is that the 0-10V output will be used in place of the PWM output.

Doubler

Before connecting anything, check to make sure that your DR2 is outputting the max current on the channel connected to the Doubler. There should be jumpers connecting the 330mA pins as well as the 60mA pins. This ensures that the output is 720mA.

 

To provide power to the Doubler, connect the output power coming from the DR2 to the bottom terminals. You’ll be connection the stripped red power wire to the positive and the black ground wire to the negative.

  

Connecting the lights to the doubler is just as easy. Insert the red power line into one of the positive terminals and the black into the negative terminal next to it. Both sides of the double output the same amount of current so pick whichever side is easier for you wiring needs. Be sure that both sides of the Doubler have an equal load. If there are two lights on one side, you should have two of the same lights on the other side as well. Wiring the lights from a doubler is the same as from the a switch.

    

The Doubler can be placed in the ceiling next to the light or if a junction box is used, inside the junction box above the light.

Structured Media Enclosure

In the enclosure you should place the power supplies, the structured wiring panels, and the DALI interface. The wiring panels and DALI interface should be secured into the enclosure on the top portion, the power supplies below. Connect the power supplies and DALI interface to the wiring panels before connecting 120V to the power supplies. One power supply should be connected to the primary input on the left panel and the other should connect to the secondary input on the right panel. More instructions for wiring the panels can be found in the wiring panel user guide.

 

The CAT5 DALI wire should be crimped into a RJ45 connector before being terminated into the lower portion of the panel. The specific terminal used only matters if you are creating a 3-way switch using the connections in the panel as described in the 3-way wiring guide.

 

It is important to mirror the DALI connection with the power connection in the upper portion. The red wire connects to the positive terminal on the right, the black to the ground in the middle, and the green to earth ground on the left side. Each homerun should have a power connection on top and a DALI connection in the same spot on the bottom.
