Electrical Box (w/mud ring)
DESCRIPTION
The OPB15 adapts Leviton low-voltage ceiling occupancy sensors
to operate on line-voltage electrical systems. Designed to control
up to 15 amps of lighting load from a single occupancy sensor. The
Power Base contains a power supply and a load switching relay. The
power supply provides Class II low-voltage power for OSCxx Series
Occupancy Sensors. The relay in the Power Base is controlled by the
occupancy sensors connected via the control input of the two-part
terminal connector. The Power Base includes zero cross switching
circuitry to minimize inrush current associated with electronic ballasts.
This reduces wear and tear on the relay contacts making the power
pack last longer.
Application Notes:
OPB15 works well where installation of a low-voltage wiring typical
with traditional power packs and sensors is difficult, inconvenient or
costly. It is ideal for existing buildings where access to wiring is limited
or for new construction with line-voltage circuiting only.
LOW-VOLTAGE CURRENT CAPACITY
OPB15 is designed for a single occupancy sensor with a maximum
current capacity of 40mA.

Preparing and connecting wires:
Step 2
Make sure the wires from the wall box are straight (cut if
necessary). Remove insulation from each wall box wire and
Sensor Power Base as shown:
5/8"
(1.6 cm)
Cut
Strip Gage (measure bare
(if necessary)
wire here)
Wiring your Sensor Power Base (Line Voltage):
Step 3
NOTE: This application is based on the wall box being
pre-installed.
Connect wires per WIRING DIAGRAM as follows: Twist
strands of each lead tightly together and, with circuit
conductors, push firmly into appropriate wire connector.
Screw connectors on clockwise making sure no bare
conductors show below the wire connectors.

WARNINGS AND CAUTIONS:
• All sensors must be mounted at least 6 feet away from air vents.
• Disconnect power when servicing fixture or changing lamps.
• Use this device only with copper or copper clad wire. With aluminum wire use
only devices marked CO/ALR or CU/AL.
Mount power base in desired electrical box
Step 4
application:
A. To mount inside 4" octagon 2.125" deep ceiling
electrical box, refer to Figure 1. Wire per Step 2.
Blue • Dress line voltage wires to provide enough clearance in electrical

box when device is installed.
• Partially thread the two #8-32 screws provided into mounting
holes of the electrical box.
Load
• Align the power base body so that it fits between the mounting
holes of the electrical box and insert over mounting screws.
• Turn counter clockwise until it reaches the stops.
