2. Squeeze the sides of the white connector cover and insert the cable’s
connector through it (see FIGURE 4-2).
FIGURE 4-2. Cable routed through the connector cover
3. Attach the cable to the mating connector on the bottom of the HMP155A
(see FIGURE 4-3).

4. Slide the white connector cover over the connector and gently push it up as
far as it will go. The white connector cover has built-in molded stops that
will only allow it to slide up so far. See FIGURE 4-4.

protective cap
5. Loosen the split-nut on the bottom plate of the 41005-5 14-plate radiation
shield.
6. Remove the yellow protective cap on the HMP155A, and insert the sensor
into the shield.
7. Tighten the hex plug such that it compresses against the body of the
HMP155A to hold it inside the 41005-5 radiation shield.
8. If mounting the 41005-5 directly to a mast, place the 41005-5 U-bolt in the
side holes and secure the 41005-5 to the mast by tightening the U-bolt nuts
(FIGURE 4-5).
9. If using a CM200-series crossarm, mount the crossarm to the tripod or
tower. Then place the 41005-5’s U-bolt in the bottom holes and secure the
41005-5 to the crossarm by tightening the U-bolt nuts (see FIGURE 4-6).
10. Route the cable to the datalogger, and secure the cable to the mounting
structure using cable ties.
