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.

4. If desired, insert the 25745 PVC coupling to reduce the conduit’s diameter

to 0.5". Route the sensor leads through the enclosure conduit to the
datalogger and peripheral terminal strips.

5. Connect sensors and peripherals to the datalogger as described in the

sensor and peripheral manuals.

6. 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.

7. Strain relief the sensor leads to the datalogger’s strain relief flanges with

the 4" cable ties.

8. 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).

9. Remove the backing from the humidity indicator card and attach the card

to the right side of the enclosure.

10. Place a roll of putty around the sensor leads where they enter the

enclosure.

11. Press the putty around the leads and into the conduit to form a tight seal.

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.

3. Route each sensor and peripheral lead through a unique compression

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.

9. Rotate each compression fitting so that the fitting clamps tightly against

the sensor cable to provide a water-tight seal (see FIGURE 3-4).

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. 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.
