This illustratio n shows how eac h component is easil y integrated into the Wattstopper PLUS Syst em. 2 INSTALLING THE SWITCH Wattstopper PLUS Slim Switches support two installation methods: surface mount or wall-box mount. NOTE: The switches may not be installed into wall boxes with line voltage wiring. In applications such as retrofit, any such wiring must be removed from the wallbox prior to installation. Wattstopper PLUS Slim Switches are for commercial use only. NOTE: Before mounting, the battery protection tab should be removed. Surface Mount: Surface mounting requires use of a Legrand radiant ® wall plate (sold sepately). The adhesive pad is suitable for mounting to multiple materials including drywall, metal, wood, glass, and some plastics. 1. Remove the wall box screws from the switch. 2. Hook the Radiant plate on the upper plate mount bracket, then press the bottom of the plate into the switch to snap on the plate. 3. Peel the adhesive protector off of the rear of the switch. 4. Align the switch with the wall and press it firmly into the mounting surface, holding pressure for 5 seconds. For surface mounting in multi-gang applications, snap-off side alignment wings are available to assist in proper alignment. 1. Press and jiggle the wall box screws from the rear to remove them from the switches. 2. Using an appropriately sized multi-gang Radiant plate (sold separately), attach each switch to the plate by hooking the plate on the upper plate mount bracket of the switch, then pressing the bottom of the plate into the switch to snap on the plate. 3. Peel the adhesive protector off of the rear of each switch. 4. Align the assembled switch bank with the wall and press it firmly into the mounting surface, spreading a firm pressure evenly across the switch bank for 5 seconds. Alignment Wings Top/Bottom Wings (for radiant wall plates) Example of 3 gang installation with alignment wings removed BUTTONS AND INDICATORS RGBW Status and Config LED on top button White Status LED on other buttons Button(s) can be set to toggle On/Off or to activate scenes Tap to increment up or down Hold to ramp ramp up or down Config Button (for device reset) Pre-programmed LED Operation Before being programmed, device LEDs are primarily used to indicate pairing status with a PLUS wireless network. Upon powering, EN-SW Slim Switches will begin searching for a PLUS network, indicated by a short green flash every 3 seconds. When attempting to join a PLUS network, the green LED will flash rapidly. After successfully joining, the green LED will illuminate solidly for 2 seconds and then turn off. Normal LED Operation (After Programming) In normal operation, the primary function of device LEDs is to…

Suchfiles are includedin CC2430DBreferencedesign[1]. The gerberfile is calledInverted_F_Antenna.spland the DXFfile is calledInverted_F_Antenna.dxf.If the antennais implementedon a PCBthat is widerthanthe antenna,avoidplacingcomponentsor havinga ground planecloseto the end pointsof the antenna.If the CADtool beinguseddoesnot supportimportinggerber or DXFfiles,see Figure1 and Table1. The antennaimpedanceis tunedto 50 ohmon the referenceboard.The impedancewill howeverbe affectedby differentsize and shapeof the groundplane,objectsin the antennanearfieldsuchas mechanicalassemblies(housing,batteries,etc.),PCBthickness,PCBmaterialand so on. It is therefore recommendedto add a pi-networkcloseto the antennafeedpointfor impedancematching.
