OPERATION

The AA47 Line-Switching Power Pack provides local switching capability to control loads based on the signal from MSC Series occupancy sensors, independently of any connection to building control systems. The AA47 routes 120/277 VAC, 60 Hz line power directly to a Form A relay contact (SPST, normally open) to control a load, and it generates full-wave, 24 VDC to power up to four MSC sensors (depending on model). The relay is rated for maximum 15 A tungsten and 20 A ballast loads.

Mounted the AA47 either inside or outside a standard junction box using a 1/2-in., threaded EMT nipple. Route power to the sensor(s) using plenum-rated cable.

INSTALLATION

1. Provide separate overcurrent protection in accordance with the National Electrical Code® and applicable local codes.

2. Use copper wire only.

3. Conrm that the device rating is appropriate for your application.

4. Set the voltage selector on the front of the unit to either 120 or 277 V, depending on your application. The unit is shipped with the selector set to 277 V.

5. Mount the power pack to a suitable junction box using the 1/2-in., threaded nipple and lock. The power pack is plenum-rated, and can be mounted to the inside or the outside of a junction box or xture in a ceiling plenum.

6. Connect the power pack as shown. Use approved wire nuts for electrical connections.
