1. Installation

CDTX-90 Series transmitters are available in two styles: panel mount and ﬁ eld 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 ﬁ eld installation options are included with the FP90UM Universal kit.

1.1 Panel 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.
