Legrand ezDALI Power Supply is a component of an ezDALI System that provides power and communication for DALI data bus, connecting ballasts within a room or zone. It supplies power for up to 64 DALI ballasts and 150 mA for occupancy sensors, enabling control of lighting fixtures and integration of occupancy sensors. The Power Supply isolates Class 2 controls from Class 1 power circuits and DALI bus, ensuring compliance with electrical codes and allowing the use of standard low-voltage occupancy sensors.

ezDALI Power Supply

Installation and Operation

The DPS150-1 /-2 Power Supply is one component

in an ezDALI System. It provides power and

communications for the Class 1 DALI data bus

connecting the ballasts within a room or zone. It

also supplies Class 2 power and inputs for the

Controller and optional occupancy sensor(s).

A complete ezDALI system includes the following:

1. Group Controller (DLC) or Group & Scene

Controller (DLCSS)

2. Power Supply (DPS series)

3. Lighting fixtures equipped with DALI ballasts

Optional components in the system are:

4. Remote Scene Switch (DSS4) for use with

Group & Scene Controller (DLCSS)

4. Relay Module (DRM) to control non-DALI fixtures

5. Occupancy Sensor(s)

Features

• Clear separation of Class 1 and Class 2 wiring in

conformance to the NEC

• Supports DALI bus and fixture power wiring in

same conduit

• 150 mA power supply to the DALI bus for control of

up to 64 DALI ballasts

• 150 mA power supply for occupancy sensors

(enough for four standard ultrasonic or dual

technology devices)

• 2-wire bus for communications with the ezDALI

Controller

• Plug-in connectors for low-voltage control devices

•Automatic message routing between Class 1 and

Class 2 control buses

• No setup or commissioning required

WARNING

Use only rapid-start sockets. Instant-start

sockets shall not be used. Instant-start sockets

short out the pins of the lamps, so the ballast

cannot provide supplemental heat to the

filaments.

Operation

The DPS150-x Power Supply provides up to 150 mA

of power at 16 VDC to the DALI bus and an additional

150 mA to the optional occupancy sensor(s).

In addition to supplying power, it provides isolation of

the Class 2 controls from the Class 1 power circuits

and DALI bus. This allows standard low-voltage

occupancy sensors to be used in the system and

assures compliance with the National Electrical Code.

Finally, the Power Supply routes messages between

the ballasts, occupancy sensors and the Controller.

Before proceeding, read the instructions on the

next three pages. If you have any questions, call

DPS150-1 / DPS150-2 ezDALI Power Supply — Installation and Operation

WARNING

Turn off power at the circuit

breaker before beginning this

installation. Wire in accordance

with the National Electrical Code

and applicable local electrical

codes.

Wire Class 1 Circuits

Refer to Figure 1

Depending on the Power Supply model

being installed, run 120 V or 277 V

power (Hot, Neutral and Ground) to the

junction box.

Pull five conductors from lighting ballasts

to the junction box (Hot, Neutral, Ground

and two DALI bus wires). DALI wires

must have the same insulation value as

the power wires and should be run in the

same conduit as the power wires.

Figure 1 – Typical ezDALI System Wiring

Mount the Power Supply

Mount the Power Supply to the junction

box using the

⁄2-inch nipple.

Connect the Class 1

Power Leads

Refer to Figure 2

1 Confirm that the voltage of the power

feed matches the rating of the Power

Supply (either 120 VAC or 277 VAC).

2 Connect the Black lead of the DPS

Power Supply to the Hot (black) wire

of the incoming power circuit and the

Hot (black) lead of the power feed to

the fixtures. Repeat for the White lead,

connecting it to the Neutral (white)

wires of the incoming power and

fixtures power feed.

3 Connect the two Purple DALI leads

from the Power Supply to the DALI bus

wires going to the ballasts. CAUTION:

Make sure the DALI bus wires are

not connected to line voltage.

4 Connect all Ground wires to the J-Box.

Power Up

Turn on the power to the Power Supply.

The Status LED should be ON steady

and GREEN. This indicates that the unit

has power and the DALI bus to the

ballasts is not shorted. If the LED is

flashing GREEN, the DALI bus to the

fixtures is shorted. If the LED is flashing

RED, the bus connecting the Power

Supply and Controller is shorted.

Connect the Class 2

Control Devices

Refer to Figure 3

Controller

Wire from the wall box to the Power

Supply. This is a Class 2 circuit and is

typically run without conduit. Refer to

your local code for requirements. We

recommend plenum-rated 2-conductor

#18 AWG wire. The Power Supply comes

with plug-in connectors for easier wiring.

Occupancy Sensor Option

The ezDALI Power Supply is compatible

with any Watt Stopper occupancy sensor

using a “B” series power pack. Follow the

installation instructions for the sensor,

replacing the power pack with the

DPS150. Maintain the Red (24 VDC

supply), Blue (control signal) and Black

(common) wiring convention. 3-conductor

#20 AWG (Red/Blue/Black) plenum-rated

wire, run and connected as above, is

recommended. See Figure 3.

The occupancy sensor provides an

occupied/unoccupied signal to the Power

Supply, which in turn sends a message

to the Controller when there is a change

of state. When the Controller receives a

message that the room has become

occupied, it signals the lighting to return

to the last occupant activated scene.

When the room becomes unoccupied,

the controller lowers the lighting for five

minutes and then turns it off. If it detects

motion during this 5-minute warning, the

lights are returned to the last scene.

Test the Installation

A complete system requires a DPS

Power Supply and a Controller (DLC2,

DLC4 or DLCSS4). Most applications

also will include an occupancy sensor.

For our purposes, we will assume an

installation with a 24 VDC ceiling sensor

and a DLC4 Controller, both of which

have been installed per their individual

instructions. To test the total system, we

will first need to commission and

demonstrate the Controller, then

commission and demonstrate the

combined operation of the sensor and

the Controller.

Controller Installation and Operation

Instructions.

1 Remove the cover plate and swing

open the Master button.

2 Press the SELECT button to sequence

through the ballasts in the room.

3 Confirm that all ballasts are responding

and that each has been assigned to

the correct group (A, B, C or D).

Troubleshooting

Lights do not turn on when power is

applied.

• Check power to fixtures.

• Confirm that ballast wiring to lamp

sockets conforms to the wiring diagram

on the ballast. Check that the lamp

socket pins are not shorted (Remove

the lamps and disconnect the socket

wires. Measure the resistance across

the contacts.)

Power Supply LED is ON steady

(Normal operation).

• RED – Sensor is unoccupied.

• GREEN – Sensor is occupied.

Power Supply LED does not turn on.

• Check the power on the supply circuit.

• Confirm that supply voltage matches

that of the device.

Power Supply LED is flashing GREEN.

• The DALI bus to the fixtures is shorted.

Turn off power and isolate the short.

Power Supply LED is flashing RED.

• The bus connecting the Power Supply

and ezDALI Controller is shorted. Turn

off power and isolate the short.

None of the fixtures respond to the

ezDALI Controller.

• The fixtures should have turned on

when power was first applied. If not,

check the lamps, power to the fixtures

and wiring of the lamp sockets.

• If the fixtures turn on when power is

cycled, but do not respond to the

Controller, first check for power to the

Controller by observing the Locator

light on the bottom bezel. If it is lit, the

Controller is receiving power.

• Check the voltage output of the Power

Supply. First, disconnect the data bus

at the Power Supply and measure the

DC voltage of the Power Supply output

to the data bus. It should be 14-16 VDC.

Repeat with the bus plugged in. The

voltage should not change. If it does,

isolate the open or short.
