Section 3. Instrumentation Installation

3.1 Enclosure, Datalogger, Power Supply

3.1.1 Enclosure

All instrumentation (datalogger, power supply, and communication

peripherals) are mounted in the enclosure. A PVC bulkhead port is installed in

the enclosure for routing the sensor and communication cables to the

instrumentation.

The “-MM” mount option is intended for mounting our enclosures to the mast

of any of our tripods. An enclosure ordered with this option will be shipped

with a three-piece bracket mounted to the top of the enclosure and an identical

three-piece bracket mounted to the bottom of the enclosure (see Figures 3.1-1,

3.1-2, and 3.1-3).

Attach the enclosure to the mast as follows:

1. Position the enclosure on the north side of the mast.

2. Place the enclosure at the desired height. Please note that the

recommended lead lengths for our sensors assume the bottom of the

enclosure is mounted 3 ft from the ground.

3. Use the furnished 2” u-bolts to secure the enclosure to the tripod mast.

4. Route the 14 AWG wire from the brass tripod grounding clamp to the

enclosure grounding lug. Strip one inch of insulation from each end of the

wire and insert the end of the wire into the grounding lugs and tighten.
