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 2 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.
INSTALLING YOUR POWER BASE
NOTE: Use check boxes when Steps are completed.
Occupancy Sensor Power Base

WARNING: TO AVOID FIRE, SHOCK, OR
Step 1
DEATH; TURN OFF power at circuit breaker
or fuse and test that power is off before wiring!
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:

Wiring your Sensor Power Base
Step 3
(Line Voltage):
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.

• 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.
• 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.
• Tighten mounting screws firmly.

WARNINGS AND CAUTIONS:
• Sensors must be mounted on a vibration free surface.
• All sensors must be mounted at least 6 feet away from air vents, air handlers, and
reflective surfaces (windows/mirrors).
• Disconnect power when servicing fixture or changing lamps.
• Use this device with copper or copper clad wire only.
