1. General Description
Environmental enclosures protect 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, Enclosure Supply Kit) and use the same brackets for mounting to
a tripod or a tower (Section 4, Attachments to an Instrument Mount). The
maintenance information (Section 5, When to Replace Desiccant, and Section
6, Resistance to Weathering) 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.
NOTE
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 28960 kit allows components to be raised 3 inches
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.
FIGURE 3-1. Securing components to the enclosure backplate
Remember to allow space for cables and cable connectors.
