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.

4. Attachment to an Instrument Mount

4.1 Tripod Mast

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 FIGURE 4-1 FIGURE 4-2, and FIGURE 4-3).
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.

4.2 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

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.
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
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 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.)
