1. General Description
Environmental enclosures protect our dataloggers and peripherals from water
and most pollutants. Our standard enclosures include the ENC10/12,
ENC12/14, ENC14/16, and ENC16/18. For cable entry, Campbell Scientific
offers a choice of one 1.5” diameter conduit, two horizontally-arranged 1.5”
diameter conduits, two vertically-arranged 1.5” conduits (ENC16/18 only), or
individual compression fittings. Multiple cables can use the conduit(s)
whereas each cable uses a separate compression fitting. The individual
compression fittings provide a more water-tight seal.
Campbell Scientific enclosures are manufactured with non-corrosive polyester
and reinforced with fiberglass. These white UV-stabilized enclosures reflect
solar radiation reducing temperature gradients inside the enclosure without
requiring a separate radiation shield. A door gasket, external grounding lug,
stainless steel hinge, and lockable hasp are included. Our enclosures were
rated NEMA 6P before being modified to include conduit(s) or compression
fittings.
Dataloggers, peripherals, and brackets are mounted to an internal plate punched
with a grid of one-inch-on-center holes. An internal backplate is included with
each ENC10/12, ENC12/14, and ENC14/16 enclosure. Two internal mounting
plate options are offered for the ENC16/18. The -SB option provides a
backplate similar to the one included with the other enclosures. The -EB
option provides both a backplate and a sideplate.

1.2 Prewired Enclosures
Besides our standard enclosures, Campbell Scientific offers prewired
enclosures that combine flexibility with ease of use. Customers have the
flexibility to choose their system components, but installation is easy because
sensors are simply attached to prewired connectors on the outside of the
enclosure.
A lot of the information provided in this manual pertains to the prewired
enclosures. Prewired enclosures are shipped with the same enclosure supply
kit (Section 2) and use the same brackets for mounting to a tripod or tower
(Section 4). The maintenance information (Sections 5 and 6) is also applicable
to our prewired enclosures.
2. Enclosure Supply Kit
Each of our enclosures is shipped with a sealed plastic bag containing an
Enclosure Supply Kit. This kit provides the materials used to seal and
desiccate the enclosures. Please note that some of the items should be saved
for future use. The contents of the enclosure supply kit are the following.

4.2 UT10 10 ft Tower
The “-TM” option is used to attach our enclosures to a UT10 tower. An
enclosure ordered with the “-TM” 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. This mounting bracket option uses the
same three-piece brackets as the "-MM" option, except the pieces are
rearranged so that the flanges are on the side of the bracket instead of in the
middle. The distance between the centers of each flange needs to be 10.25”
(see Figures 4-4, 4-5, and 4-6).
Attach the enclosure to the UT10’s tower legs as follows:
1.
Position the enclosure on the north side of the tower.
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 1.5” u-bolts to secure the enclosure to the tower legs.
4.
Route the 14 AWG wire from the brass tower 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
4.3 UT20 or UT30 Tower
The “-TM” option is used to attach our enclosures to a UT20 or UT30 tower.
An enclosure ordered with the “-TM” 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. This mounting bracket option uses the
10
ENC10/12, ENC12/14, ENC14/16, ENC16/18
same three-piece brackets as the "-MM" option, except the pieces are
rearranged so that the flanges are on the side of the bracket instead of in the
middle. The distance between the centers of each flange needs to be 17” (see
Figures 4-4, 4-5, and 4-6).
NOTE
Enclosures with the "-TM" option are shipped configured for the
UT10 tower. Steps 1 through 3 of the following procedure are
for configuring the bracket for attachment to a UT20 or UT30
tower.
Attach the enclosure to a UT20 or UT30 tower as follows:
1.
Remove the bolts and nuts connecting the bracket to the enclosure.
2.
Slide out the flange sections so that the distance between the centers of
each flange is 17" (see Figure 4-4).
3.
Reattach the bracket to the enclosure using the original bolts and nuts.
4.
Position the enclosure on the north side of the mast.
5.
Place the enclosure at the desired height. Please note that the
recommended lead lengths for our sensors assume the bottom of the
enclosure is 3 ft from the ground.
6.
Use the furnished 1.5” u-bolts to secure the enclosure to the tower legs.
7.
Route the 14 AWG wire from the brass tower 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.

4.4 Tripod Leg Base
The “-LM” mount option is intended for attaching an enclosure to the leg base
of a CM106, CM106K, CM110, CM115, or CM120 tripod.
NOTE
The ENC16/18 can be mounted to the leg base of a CM106 or
CM106K only.
An enclosure ordered with this option will be shipped with a bracket attached
to each side of the enclosure and a u-bolt bracket. A 19124 bracket must also
be attached to some tripods (see Figure 4-7).
NOTE
For tripods requiring 19124 bracket, the bracket may not be preinstalled on the tripod at the factory. In this situation, the 19124
bracket and mounting hardware will be shipped with the tripod
and will need to be installed as shown in Figure 4-7.
The CM106 and CM106K tripods have flanges built into the
body of the tripod and do not require the 19124 bracket.
Attach the enclosure to the leg base as follows:
1.
Slide the keyhole notches in the upper and lower corners of the –LM
bracket over the two extended Phillips head screws located on the tripod.
The CM106 and CM106K have hooks extending from the tripod body in
place of the Phillips screws.
2.
Place the flange of the tripod’s bracket into a notch in one of the
enclosure’s brackets (see Figures 4-7, 4-8, and 4-10).
3.
Attach the u-bolt bracket on the other enclosure bracket (see Figure 4-9).
4.
Use the furnished 2.5” u-bolt to secure the enclosure bracket to a tripod leg
(see Figures 4-9 and 4-10). The CM106K requires a user-supplied
5/16-18 x 1.5000” u-bolt due to the tripod’s smaller leg size.
5.
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.

4.4.1 Mounting More Than One Enclosure on a Tripod Leg (CM110,
CM115, CM120)
It is possible to mount two enclosures back-to-back on the CM110, CM115,
and CM120 tripods. If the enclosures are different sizes, mount the smaller
enclosure first, followed by the larger enclosure. If the enclosures are the same
size, use two 5/16-18 x 3.50” bolts in place of u-bolts to anchor the two
enclosures together.
FIGURE 4-11. Mounting Two Enclosures on a Single Tripod Leg
4.5 Pole Mount
The “-PM” mount option is intended for mounting our enclosures to a vertical
pole. An enclosure ordered with this option will be shipped with the brackets,
metal bands, and mounting hardware needed to secure the enclosure. The metal
bands are routed through the brackets, and then around a vertical pole. They are
then anchored in place using screw clamps.
Attach the enclosure to a vertical tube as follows:
1.

Position a bracket at the top of the enclosure as shown in Figure 4-12.
Secure it with a bolt, washer, and locknut at each end. Attach the lower
bracket in the same manner, rotating the bracket so it extends below the
enclosure.

adjustments.
8.
Insert the Screw Threads into the Screw Clamp and tighten, using a
flathead screwdriver or nut driver.
9.
Repeat steps 4–7 for the lower strap.

5. When to Replace Desiccant
The humidity indicator card or optional CS210 Humidity Sensor indicate when
the desiccant needs to be replaced.
CAUTION
Campbell Scientific strongly suggests replacing desiccant
instead of reactivating old desiccant. Improper reactivation
can cause the desiccant packets to explode. If you are
determined to reactivate old desiccant packets, follow one of
the procedures provided in Appendix C.
5.1 Humidity Indicator Card
The humidity indicator card has three colored circles that indicate the
percentage of humidity. Desiccant packets inside the enclosure should be
replaced with fresh packets when the upper dot on the indicator begins to turn
pink. The indicator card does not need to be replaced unless the colored circles
overrun.
5.2 Optional CS210 Humidity Sensor
The CS210 Enclosure Humidity Sensor contains an Elan HM2000 series
precision bulkpolymer relative humidity sensor to measure relative humidity
inside an enclosure. When the measurements exceed 35% relative humidity,
replace the desiccant packets. Refer to the CS210 manual for sensor
specifications, installation procedures, and programming information.
6. Resistance to Weathering
Our enclosures are coated to protect them from UV rays and other weathering.
However, the outer surface of enclosures exposed to extreme weather (rain,
wind, and/or UV rays) may erode so that glass fibers become apparent. The
depth of the erosion is superficial and only affects the aesthetic appeal (i.e.,
does not reduce the effectiveness in protecting equipment).
Customers who are worried about weathering can periodically rub the
enclosure with petroleum jelly or a Canuba-based car wax. The appearance of
an enclosure that has already been eroded can be sprayed with clear acrylic
paint or coated with primer and white paint. Follow the procedure provided in
either Section 6.1 or Section 6.2 to ensure proper bonding.
6.1 Clear Acrylic Paint
1.
Use a rag and possibly a solvent to clean the outside of the enclosure.
Solvents that can be used include rubbing alcohol, a water solution of
alkaline or caustic salts, domestic cleaning products such as Spic & Span,
aromatic hydrocarbon solvents (benzene, xylene), butyl acetate, and glycol
acetate.
2.
If a solvent was used, carefully rinse and dry enclosure.
19
ENC10/12, ENC12/14, ENC14/16, ENC16/18
CAUTION
3.
Use a fine grain sandpaper to gently sand the enclosure surface; if the
surface of the enclosure is sufficiently rough, this step may be skipped.
4.
Spray with clear acrylic paint.
Properly ventilate the area while using solvent and paint.
Wear safety goggles, mask, and gloves while sanding.
6.2 Primer and White Paint
CAUTION
20
1.
Use a rag and possibly a solvent to clean the outside of the enclosure.
Solvents that can be used include rubbing alcohol, a water solution of
alkaline or caustic salts, domestic cleaning products such as Spic & Span,
aromatic hydrocarbon solvents (benzene, xylene), butyl acetate, and glycol
acetate.
2.
If a solvent was used, carefully rinse and dry enclosure.
3.
Use a fine grain sandpaper to gently sand the enclosure surface; if the
surface of the enclosure is sufficiently rough, this step may be skipped.
4.
Spray with primer that is compatible with fiberglass.
5.
Paint the enclosure with a white paint that is compatible with fiberglass
and resistant to extreme weather. The paint must be white because the
white color reflects solar radiation.
Properly ventilate the area while using solvent and paint.
Wear safety goggles, mask, and gloves while sanding.

Appendix B. 25458 DIN-Rail Terminal Kit
B.1 Introduction
The 25458 kit can facilitate wiring when many wires need to be connected to
one terminal. The kit contains one 15906 5-inch DIN-Rail Mounting Bracket,
two 505 screws, two 6044 grommets, and two 15908 DIN-Rail Stoppers. A
complete configuration will also include #15920 Terminal Strips, #15907 End
Plates, and #15909 Jumpers. The stoppers, terminal strips, and end plates are
mounted onto the DIN Rail bracket. The DIN Rail bracket is mounted to an
enclosure backplate using the kit’s screws and grommets.
One 15920 terminal strip consists of three spring-loaded "guillotine" terminals
that provide connection points for individual wires. Up to 20 of these terminal
strips may be fastened to the DIN Rail bracket. The 15907 End Plates separate
the terminal strips. The 15909 jumpers are used to electrically connect the
terminals. A stopper needs to be on each end of the terminal strip assembly.
B.2 Installation Procedure
1.
Mount the 15908 DIN Rail Stoppers, 15920 Terminal Strips, and 15907
End Plates onto the 15906 DIN Rail Bracket (see Figures 1 through 3).

Appendix C. Reusing Desiccant
Because desiccant is inexpensive, most users replace the desiccant instead of
reactivating saturated desiccant. However some customers wish to reactivate
saturated desiccant. To do this, care must be taken to prevent the desiccant
packets from exploding during the reactivation process. This problem is
caused by using too rapid of a heating process. If the heating process is too
rapid, water vapor is released too quickly causing too much pressure to build
up inside the packets so that the packets burst. The following methods will
prevent this from happening:
C.1 Recirculating Oven Method
The optimum situation for reactivation is to use a recirculating oven that has a
ramping temperature. The desiccant should bake for 16 hours, and the final
temperature should be 250°F.
C.2 Standard Oven Method
1.
Bake at an oven temperature of 125°F for a couple of hours.
2.
Increase the oven temperature to 175°F and bake at this temperature for a
couple of hours.
3.
Increase the oven temperature to 245° to 250°F and bake at this
temperature for 12 hours.
C.3 Baby Food Jar Method
1.
Open the desiccant packets and empty the desiccant granules onto a
cookie sheet.
2.
Bake at 245° to 250°F for 16 hours.
3.
Pour the desiccant granules into an empty baby food jar.
4.
Place the open jar inside the enclosure.
