1. General Description
Environmental enclosures protect our dataloggers and peripherals from water
and most pollutants. Our standard enclosures include the ENC10/12,
ENC10/12R, 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.
Besides our standard enclosures, Campbell Scientific offers prewired
enclosures that combine flexibility with ease of use. Prewired enclosures
include the PWENC12/14, PWENC14/16, and PWENC16/18. 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.
Most 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.
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. (The ENC10/12 and ENC10/12R have
a grid of one-half-inch-on-center holes, allowing a CR1000 datalogger to be
mounted horizontally within the enclosure.) An internal backplate is included
with each ENC10/12, ENC10/12R, 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.

3. Mounting Equipment Inside the Enclosure
3.1 Enclosures with One or Two 1.5" Conduits
1. If installing the optional Door Switch Indicator, follow the procedure
described in Appendix A.
2. If installing the 25458 or 28532 DIN-Rail Terminal Kit, follow the
procedure described in Appendix B. The 25458 kit facilitates wiring when
many wires need to be connected to one terminal.
3. If installing the 28960 Stack Mounting Kit, follow the procedure described
in Appendix C. The 28906 kit allows components to be raised 3 in above
the back plate, allowing one component to be stacked above another to
save space. Raising a component from the back plate is also done to
improve access to a component that may be partially blocked by other,
taller equipment mounted in the enclosure.

3.2 Enclosures with Individual Compression Fittings
1. If installing the optional Door Switch Indicator, follow the procedure
described in Appendix A.
2. Use the #6 screws and plastic grommets (FIGURE 3-1A) to mount
additional peripherals to the enclosure backplate (FIGURE 3-1B).
Dataloggers, power supplies, and most peripherals are usually attached to
the backplate prior to shipment from the factory or are supplied with
additional screws and grommets.
To insert the grommet, push the points of the flanges into the center of any
square hole. To remove a grommet without damage, remove the enclosure
backplate and use pliers to pinch the grommet flanges together.
NOTE
Remember to allow space for cables and cable connectors.

fitting (see FIGURE 3-4).
4. Connect sensors and peripherals to the datalogger as described in the
sensor and peripheral manuals.
5. Secure sensor and peripheral leads to the side of the enclosure using 8"
cable ties and cable tie tabs (see FIGURE 3-2).
NOTE
The adhesive of the cable tie tab may not stick during extremely
cold temperatures or extremely high humidity. In these
situations, fasten the cable tie tab to the backplate using a #6
screw and grommet or run the cable tie through two of the
enclosure backplate holes.
6. Strain relief the sensor leads to the datalogger’s strain relief flanges with
the 4" cable ties.
7. Place two of the desiccant packs from the Enclosure Supply Kit inside of
the enclosure. Reseal the other two inside the plastic bag to use later (see
Section 5).
8. Remove the backing from the humidity indicator card and attach the card
to the right side of the enclosure.

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 FIGURE 4-4, FIGURE 4-5, and FIGURE 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
11
ENC10/12, ENC10/12R, ENC12/14, ENC14/16, ENC16/18, PWENC12/14, PWENC14/16, and PWENC16/18
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
FIGURE 4-4, FIGURE 4-5, and FIGURE 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.

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
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).
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 FIGURE 4-7, FIGURE 4-8, and FIGURE 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 FIGURE 4-9 and FIGURE 4-10). The CM106K requires a usersupplied 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.

5. When to Replace Desiccant
The humidity indicator card or optional CS210 Humidity Sensor indicate when
the desiccant needs to be replaced.
CAUTION
Because desiccant is inexpensive, Campbell Scientific
recommends replacing desiccant packets once they
become saturated rather than attempting to reactivate the
desiccant. This prevents the possibility of the desiccant
packets exploding during the reactivation process due to
heating the desiccant packets too rapidly.
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.

ENC10/12, ENC10/12R, ENC12/14, ENC14/16, ENC16/18, PWENC12/14, PWENC14/16, and PWENC16/18
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.
CAUTION
Properly ventilate the area while using solvent and paint.
Wear safety goggles, mask, and gloves while sanding.
6.2 Primer and White 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.
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.
CAUTION
Properly ventilate the area while using solvent and paint.
Wear safety goggles, mask, and gloves while sanding.

Appendix A. Door Switch
A.1 Installation Procedure
1. The Door Open Indicator Kit contains several small brackets that are used
to mount the sensor and magnet to the enclosure case and door. Which
brackets are used depends on the style of enclosure. Use the following
guide to determine the proper brackets:
a. The Door Open Indicator is mounted at the upper right corner of
the enclosure. The enclosure DOOR determines which bracket is
used to mount the sensor inside the enclosure CASE. If there is
an offset near the edge of the enclosure door (see below), the
sensor will be mounted with the brackets shown.

2. Using the brackets determined in step 1, assemble the sensor and place it
in the upper right corner of the enclosure case. Align the top of the sensor
with the inside edge of the sensor case as shown. Do not allow the sensor
to extend beyond the edge of the enclosure case. Using a marker, mark the
locations for two mounting holes to secure the sensor bracket.
A-2
Appendix A. Door Switch
3. Assemble the sensor magnet with the bracket determined in step 1. Place
the bracket in position so the edge of the sensor magnet does not extend
beyond the internal edge of the door. Mark the locations for two mounting
holes to secure the sensor magnet bracket. Important: The mounting holes
for the sensor magnet bracket must align with the holes for the sensor
bracket for the door open switch to function properly.

4. Drill small pilot holes for all four mounting holes from the inside of the
case.
5. Drill the final holes for the brackets from the outside of the enclosure
using a #22 (.157") drill bit.
NOTE
Drilling the holes in this manner will ensure the enclosure finish
does not crack.
6. From the outside of the enclosure, insert two screws through the newly
drilled holes in the case.

Appendix B. 25458/28532 DIN-Rail Terminal Kits
B.1 Introduction
The 25458 (5-inch) or 28532 (9-inch) kit can facilitate wiring when many
wires need to be connected to one terminal. The kit contains one 15906 5-inch
DIN-Rail (or one 28531 9-inch DIN-Rail) Mounting Bracket, 505 screws, 6044
grommets, and 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 25458 DIN-Rail bracket. The 28532 DIN-Rail
bracket holds up to 36. 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 DIN-Rail Bracket (see FIGURE B-1 through FIGURE
B-3).

Appendix C. 28960 Stack Mounting Kit
C.1 Introduction
The 28960 Stack Mounting Kit is used to raise a component 3 in above the
surface of the back plate. This is beneficial when an enclosure nears its holding
capacity of components. Using the Stack Mounting Kit allows one component
to be stacked above another, saving space in the enclosure. For example,
FIGURE C-1 and FIGURE C-2 show a CR1000 mounted above an
AM16/32B. Any component mounted below the Top Grid must be fully wired
prior to installing the Top Grid. Note that in this example, the four grommets
used to mount the CR1000 to the Top Grid pass through the Top Grid into the
Legs using the same hole pattern as the CR1000.

The Stack Mounting Kit consists of a Top Grid, two Legs, eight Grommets,
and eight Screws (FIGURE C-3). Besides the standard one-inch-on-center
holes, the Top Grid also contains sixteen smaller, round holes. These holes are
used by wire-ties to secure any loose wiring.
If the Stack Mounting Kit is only being used to raise a single component, the
Top Grid is optional. The component can be mounted directly to the two Legs
using the Grommets and Screws. This allows the raised area to be tailored to
the component's size. FIGURE C-4 shows a CR1000 mounted to the Legs
without using the Top Grid.

C.2 Mounting Procedure
1. Determine the spacing needed between the two legs.
2. Secure the legs to the back plate using screws and grommets. If a
component is to be mounted under another and shares the same mounting
holes as the leg, mount the pieces in the following order.
Back Plate < Grommet < Leg < Component < Screw
3. Fully wire the bottom component before proceeding.
4. Place the Top Grid in position over the Legs. Insert Grommets where
required for the component to be mounted. If the Top Grid is not going to
be used, insert the Grommets directly into the top of the Legs.
5. Place the top component in position and secure it with Screws.

Appendix D. Keeping Insects Out Of the Enclosure
Campbell Scientific has published an application note regarding how to keep
pests away from the equipment. It is found on the Campbell Scientific website
(www.campbellsci.com/app-notes) and is called “Keeping Pests Away from
Equipment (5-Y).”
Here are two methods from the application note on how to keep insects out of
the enclosure.
1. Place moth balls or crystals in enclosures to prevent fire ants, wasps,
spiders, and other insects from nesting.
CAUTION
The fumes of moth balls or crystals could be hazardous.
Therefore, enclosures that contain moth balls or crystals
should be opened in a well-ventilated area.
2. Put animal ear tags in the enclosure. Apparently, some ear tags are treated
with an insecticide. Talk with personnel in an agricultural store to
determine the best ear tag for controlling the pests in your area. (This
technique originated in Southern Texas.)
