6.1.6 Crossarm Attachment
Attach the CM202 (2 ft, 0.6 m), CM204 (4 ft, 1.2 m), or CM206 (6 ft, 1.8 m)
crossarm to the tripod mast as shown in FIGURE 6-13. For wind sensors, the
crossarm should be approximately 103 inches above the ground for a 3 m
mounting height, or 64 inches for a 2 m mounting height. Typically the
crossarm is oriented east/west for wind sensors, north/south for pyranometers.

6.1.7 Enclosure Attachment
The ENC10/12, ENC12/14, ENC14/16, and ENC16/18 enclosures can be
ordered with mounting brackets for the CM100-series tripods. All enclosure
models can be mounted to the tripod mast (above the legs) with the –MM Mast
Mount bracket option. All enclosure models except the ENC16/18 can be
mounted to the tripod base and leg with the –LM Leg Mount bracket option.
Two enclosures with the –LM brackets can be mounted in a “back to back”
configuration.
6.1.7.1 Enclosure Mounting to Tripod Mast
An enclosure ordered with the –MM bracket has a three-piece top and bottom
brackets with a U-bolt for each bracket.
Attach an enclosure with the –MM mounting bracket to the tripod mast as
follows:
• Remove the U-bolts, washers, and nuts from the brackets.
• Position the enclosure against the tripod’s mast (north side recommended).
• Install the U-bolts, flat washers, lock washers, and nuts. Tighten the nuts
until the lock washers are compressed.
