- Pliers
Caution
A qualified electrician must perform installation and maintenance per state, local, and National Electrical Codes (NEC) and requirements.
Installation
The DALI PSU-6 can be mounted either to a junction box or to a fixture.
Note: In some cities, such as in Chicago, the nipple-mounted DALI PSU must be installed inside a metal enclosure, such as a 4-inch x 4-inch junction box. Refer to the section DALI PSU-6 Inside of a J-Box.
Step 1: Switch off the circuit breaker supplying power to the power supply box or the luminaire.
Step 2: Loosen the two screws on the junction box's cover plate and slide out the cover plate. Remove a ½" knockout on the J-box.
Step 3: Route the wires from the DALI PSU-6 through the knockout hole and pull the wires into the box.
Step 4: When routing the wires through the knockout, route the cables through the locknut and thread the locknut inside of the J-box to tighten it.
Step 5: Connect the two groups of wires, high voltage, and low voltage wires, according to the code requirements. Refer to the corresponding section: Wiring the High Voltage Wires, and Wiring the Low Voltage Wires.
DALI PSU-6 Inside of a J-Box
Step 1: To mount the PSU-6 inside a 4-inch x 4-inch J-box, mount it with the mounting nipple protruding into the adjoining J-box, as shown. Use the lock nut on the PSU nipple to secure both J-boxes together. Route the wires in the adjacent J-box as per the instructions below.
Wiring the High Voltage Wires
Step 1: Connect the DALI PSU power input wires to the branch circuit feed (black=Line, white=Neutral) using wire nuts. Make the connections in the J-box per code.
Wiring the Low Voltage Wires
Note: Per NEC and local code compliance, DO NOT connect the low voltage wires in the same J-box as the high voltage wires. The low voltage wires are enclosed in a 600V rated sleeve sufficiently long to pass through the high voltage J-Box, eliminating the need for further separation or barrier. Use a bush or clamp in the knockout where the low voltage wires exit the J-box through the knockout.
The DALI PSU-6 can provide power to the DALI Bus and can source up to 200mA current. The violet wire is DA+ output; the grey wire is DA- output.
- Connect the DA+ and DA- output from the DALI PSU to the DALI port of the DALI device to be powered.
- For multiple DALI devices on the same DALI bus powered by a single DALI PSU, connect all DALI ports from the DALI device in parallel. Note the polarity of all the devices; connect violet to violet and grey to grey, DA+ to DA+ and DA- to DA-.
Completing the Installation
Step 1: Bend wires into place such that the J-box cover can easily be reattached.
Step 2: Install the covers for the J-box and ballast cavity, apply power to the newly wired lighting fixture, or turn the power on to the power-supply box.
Step 3: The Enlighted sensor will perform a wiring test based on the sensor commissioning status or programming.
