DPS150-1 / DPS150-2
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
our Service Team at: 888-852-2778.

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
1
⁄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.
Commission and
Demonstrate the Controller
Refer to DLCSS4-x or DLC4-x/DLC2-x
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.
