2.1. 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. The cutout must be
92 mm x 92 mm. Recommended clearance on all sides between instruments is 25 mm/1 in.
2. Slide the instrument into the cutout from the front of the panel.
3. Slide the 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.

3. Electrical
Connections
Caution:
Failure to fully open terminal jaws before removing wire may permanently damage instrument.
Wiring Procedure
1. Remove 0.5 - 0.625 in. (13-16 mm) of insulation from wire end.
2. Press the orange terminal lever downward with a small screwdriver to open terminal jaws.
3. Insert exposed (non-insulated) wire end in terminal hole until it bottoms out.
4. Release orange terminal lever to secure wire in place. Gently pull on each wire to ensure a good connection.
Wiring Removal Procedure
1. Press the orange terminal lever downward with a small screwdriver to open terminal jaws.
2. When fully open, remove wire from terminal.
Wiring Tips:
• Do not route sensor cable in conduit containing AC power wiring. Electrical noise may interfere with sensor signal.
• Routing sensor cable in grounded metal conduit will help prevent electrical noise and mechanical damage.
• Seal cable entry points to prevent moisture damage.
• Only one wire should be inserted into a terminal. Splice double wires outside the terminal.
• The cable length from the sensor to the transmitter must not exceed 400 ft (122 m).
• For best performance, ground the sensor SHIELD wire to a local earth ground at a point near the sensor.
