Page 19: Installation
3 Installation INSTALLATION Selecting Location Select a location that represents well the area of interest. Interior walls and columns are typically suitable locations. The installation height should be 1.2 ... 1.8 m (4 ... 6 ft). Figure 11 Examples of Good Installation Locations Seal the cable opening when bringing a cable through the wall. - Page 20 3 Installation Avoid installing in the following locations: Near doors or windows. Near heat and moisture sources. In direct sunlight. In locations that are blocked by furniture. Close to the discharge of the supply air ducts. On the floor or the ceiling. On points that experience excessive vibration.

Page 22: Installing The Mounting Base
3 Installation Installing the Mounting Base The transmitters are designed to be installed on a mounting box or directly to a wall surface. Use the mounting holes to attach the mounting base securely. Use at least two screws (not included). The mounting holes are suitable for the most common European, American, and Asian mounting boxes. -
Page 23: Wiring
3 Installation Wiring Connect the wiring to the screw terminals on the mounting base. The terminal assignments are marked next to the screw terminals. Do not connect wiring to unmarked terminals. Maximum wire size is 2 mm (AWG14). Route the cable through the hole in the mounting base if possible. -
