1. Installation

CDTX-90 Series transmitters are available in two styles: panel mount and field mount. The panel mount is supplied with the necessary hardware to install the transmitter. This manual includes complete panel mounting instructions.

Field mounting requires a separate mounting kit. The FP90UM Universal kit enables the transmitter to be installed virtually anywhere. Detailed instructions for field installation options are included with the FP90UM Universal kit.

1.1Panel Installation

1.The panel mount transmitter is designed for installation using a 1/4 DIN Punch. For manual panel cutout, an adhesive template is provided as an installation guide. Recommended clearance on all sides between instruments is 1 inch.

2.Place gasket on instrument, and install in panel.

3.Slide mounting bracket over back of instrument until quick-clips snap into latches on side of instrument.

4.To remove, secure instrument temporarily with tape from front or grip from rear of instrument. DO NOT RELEASE. Press quick-clips outward and remove.
