Installation Instructions
For use with microOS
Mounted Occupant Sensor and
0-10 Volt Ballast Controls
Overview
The Lutron Power Pack (Diagram 1) is for
use with Lutron microOS Ceiling Mounted
Occupant Sensor and Lutron 0-10 Volt
Ballast Controls. The Power Pack
combines a Class 2, 15VDC power
supply and a heavy duty Form A relay.
Check the Application
The Power Pack can be used on either
120 or 277 VAC circuits. Do not exceed
the following power ratings:
16A Lutron Ballast @ 120VAC
16A Lutron Ballast @ 277VAC
For Applications with Lutron microOS
Occupant Sensors
A single Power Pack can power up to five
Lutron microOS Occupant Sensors
(MOS-CM-15-WH). As many as ten
Power Packs can be connected to one
occupant sensor for switching multiple
circuits.
For Applications with Lutron 0-10 Volt
Ballast Controls
One 0-10 Volt Ballast Control can
operate up to three Power Packs.
However, one Power Pack can not be
used with more than one 0-10 Volt
Ballast Control.
The 0-10 Volt wiring for this unit should
not exceed 500 feet with No. 20 AWG
wire. Note: For long 0-10 Volt wiring
runs, or where excessive electrical noise
exists, shielded cable or conduit is
required.
Mounting Instructions
The Power Pack is designed to be
mounted in a 1/2-inch knockout of a
standard junction box (supplied by
others) as shown in Diagram 2. The line
voltage connections to the power wires
are made inside the junction box. The
Class 2 wire connections must be made
outside the junction box.
