ENC 8/10, ENC 10/12, ENC 12/14,
ENC 14/16, ENC 16/18 and
AM-ENC/ENCT Enclosures

This manual describes Campbell Scientific’s ENC 8/10, ENC 10/12, ENC 12/14, ENC 14/16,
ENC 16/18 and AM-ENC/ENCT enclosures. This information should be used in conjunction
with other information given in the datalogger or weather station manuals.

1. Description

These enclosures are made of white fibreglass-reinforced polyester. The colour of
the enclosure and the environmental sealing mean that there is no need for a
conventional radiation/rain shield. The enclosures can be wall mounted as
supplied, or pole mounted using the optional enclosure mounting brackets. The
door is fitted with a catch which can accept a padlock if required.

The enclosure is fitted with an anodised aluminium chassis plate which is punched
with an array of holes. The holes accept plastic inserts for accepting screws for the
attachment of power supplies, dataloggers and peripherals. These plastic fittings
can easily be inserted by hand allowing the rapid mounting of components inside
the enclosure.

A small cable gland is fitted to the base of the enclosure and a venting plug is
fitted to this gland. The plug allows pressure equalisation between the inside and
outside of the enclosure (which is required when using barometric or gauge
pressure transducers) and also prevents pressure build-up in the enclosure in the
event of a system failure when charging lead-acid batteries. A blanking plug is
supplied which can replace the porous venting plug, if this is not required.

We recommend that sealed environmental connectors are used for the entry of
sensor leads into the enclosure. However, a large cable gland is also fitted which
can be used for the direct entry of one or more cables into the enclosure.

An earthing boss is also provided for the connection of an external earth lead.
Internally an earth wire is fitted which should be taken to the main earth point
inside the enclosure (normally on the datalogger).

Four bags of desiccant are supplied with the enclosure and are used to maintain a
dry atmosphere inside the enclosure.

2. Installing Components in the Enclosure

When the enclosure is bought as a configured system, the components will be pre­fitted. If they are not fitted the convention is that the power supply (normally a
PS100E) is mounted in the top of the enclosure (this is the end opposite to that
where the cable glands are fitted). The datalogger is fitted next from the top and
then any peripherals at the bottom.

To fit the components, first work out exactly which holes are to be used and then
push the nylon inserts into the holes in the chassis plate. A 3.5mm or 6-32 thread
screw can then be screwed into the insert. Normally enough inserts and screws are
supplied with each datalogger or enclosure to cater for all peripherals.

ENC 8/10, ENC 10/12, ENC 12/14, ENC 14/16, ENC 16/18 and AM-ENC/ENCT Enclosures

Some peripherals need adaptor plates for these enclosures. The
adaptor plates are not always supplied with the peripheral. Please
contact Campbell Scientific if you experience any problems.

Only one small peripheral can be fitted into the ENC 10/12 enclosure. The ENC
12/14 will take the majority of peripherals including an AM16/32, for which there
are two extra mounting holes in the lower half of the grid of holes.

Figure 2-1 ENC 12/14 fitted with a power supply, logger and multiplexer

The AM-ENC enclosure will accept up to two AM16/32s or one older (now
superseded) AM416 multiplexer.

If installing the DIN-Rail Terminal Kit (010211), follow the procedure described
in Appendix A. The 006706-002 kit facilitates wiring when many wires need to be
connected to one terminal.

3. Power Supplies

The enclosures are designed to accept the PS100E, PS17E or PS24E power
supplies. These should be mounted as described above.

Do not ship the enclosure with the large lead acid batteries
installed inside without adequate internal packing, as there is
a risk that the batteries might break loose and cause serious
damage to other peripherals.

NOTE

CAUTION

4. Earth Connections

Connect the earth boss on the base of the enclosure externally to a good earth
point, e.g. an array of ground spikes, using a large diameter copper cable (approx.
16mm2, similar to that supplied by Campbell Scientific with weather stations, etc.).
Internally the earth wire should be connected to the main earth point in the
enclosure, which is usually the datalogger wiring panel.

In installations where additional lighting protection devices are fitted inside the
enclosure, e.g. a RAD-SP spark arrestor, it may be more applicable to route a
separate earth wire from the boss to the arrestor, in addition to the wire to the
datalogger.

Because the chassis plate is anodised and plastic panel inserts are
used, do not rely on the chassis plate as a way of connecting the
earth points of different peripherals. Instead, run additional wires
back to one common earth point to ensure good connection.

5. Sealing the Enclosure

If supplied with environmental connectors, the enclosure is fully weatherproof
when all the connectors are plugged in and the blanking plug is fitted to the large
cable gland. If any connector is not plugged in the chassis socket should be fitted
with a protective cap to prevent moisture entry. If the large cable gland is being
used for cable entry any gaps around the cables should be filled with a suitable
mastic compound such as ‘Plumbers Mate’ or silicone rubber compound.

Do not use bath or tile sealant, which gives off corrosive
fumes that can damage circuit boards. Use proper electronic

grade silicone rubber or plumber’s putty.

6. Desiccant

The desiccant bags should be removed from the plastic bags in
which they are shipped before placing them inside the enclosure.

Four 100g bags of desiccant are supplied with each enclosure. Desiccant use
depends on your application (see below) but for use in average UK conditions
place only two bags into the enclosure and re-seal the other two bags in the plastic
shipping bag as replacements for when the initial bags need to be dried out. The
bags can be rotated in this way many times. Desiccant bags can be dried out by the
following method:

1. Arrange the bags on a wire tray in a single layer to allow for adequate air flow

around the bags during the drying process. The oven’s inside temperature

should be room or ambient temperature (25ºC - 30ºC). A CONVECTION,
CIRCULATING, FORCED AIR TYPE OVEN IS RECOMMENDED FOR
THIS REGENERATION PROCESS. SEAL FAILURES MAY OCCUR IF
ANY OTHER TYPE OF HEATING UNIT OR APPLIANCE IS USED.

2. When placed in a forced air, circulating air, or convection oven, allow a

minimum of 4 to 5 cm of air space between the top of the bags and the next
metal tray above the bags. If placed in a radiating exposed infrared element
type oven, shield the bags from direct exposure to the heating element, giving

NOTE

CAUTION

NOTE

the closest bags a minimum of 40 cm clearance from the heat shield.
Excessive surface film temperature due to infrared radiation will cause the
Tyvek material to melt and/or the seals to fail.

Seal failure may also occur if the temperature is allowed to increase rapidly.
This is due to the fact that the water vapour is not given sufficient time to
diffuse through the Tyvek material, thus creating internal pressure within the
bag, resulting in a seal rupture. Temperature should not increase faster than

0.1º to 0.3ºC per minute.

3. Set the temperature of the oven to 118ºC, and allow the bags of desiccant to

reach equilibrium temperature. WARNING: Tyvek has a melt temperature of
121 - 127ºC. (NON MIL-D-3464E activation or reactivation of both silica gel
and Bentonite clay can be achieved at temperatures of 104ºC).

4. Desiccant bags should be allowed to remain in the oven at the assigned

temperature for 24 hours. At the end of the timer period, the bags should be
immediately removed and placed in a desiccator jar or dry (0% relative
humidity) air tight container for cooling. If this procedure is not followed
precisely, any water vapour driven off during reactivation may be re-adsorbed
during cooling and /or handling.

5. After the bags of desiccant have been allowed to cool in an airtight desiccator,

they may be removed and placed in either an appropriate type polyliner tightly
sealed to prevent moisture adsorption, or a container that prevents moisture
from coming into contact with the regenerated desiccant.

Some care should be taken when re-activating desiccant
bags. If heated in an oven which is too hot, the bags may
burst. If in any doubt, we recommend purchasing new
desiccant packs instead of oven drying.

The enclosure is supplied with a humidity indicator card, which provides a general
indication of humidity inside the enclosure and also indicates when the desiccant
bags need to be replaced. Remove the backing tape from the self-adhesive strip,
and attach the card in a suitable position on the inside wall of the enclosure.
The frequency of desiccant bag exchange varies with the application. Using the
enclosures in high humidities or where there are large daily temperature changes
will mean that the bags have to be exchanged more frequently, e.g. as frequently as
every 3-4 weeks. The desiccant in systems subject to small daily temperature
changes and moderate humidities should last for several months.

When enclosures are used on sites which have extended
maintenance periods (e.g. yearly) we strongly recommend that extra
desiccant packs are purchased and placed in the enclosure to ensure
that it remains moisture free during this period.

Fitting the blanking plug in place of the porous vent plug in the small cable gland
will greatly extend the life of the desiccant, but this is only possible in certain
applications (see above).

Failure to use or exchange the desiccant may lead to
condensation inside the enclosure. Not only will this lead to
corrupted data but, in the long term, can also cause corrosion
which is expensive to repair.

7. Attachment to an Instrument Mount

7.1 Tripod Mast

The mast 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 three­piece bracket for mounting on the top of the enclosure and an identical three-piece
bracket for mounting to the bottom of the enclosure (see Figures 7-1,
7-2, and 7-3).

Attach the enclosure to the mast as follows:

1. Position the enclosure on the north side of the mast.

2. Use the furnished 62 mm centre u-bolts to secure the enclosure to the tripod

mast.

3. 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.

7.2 Tower mounting

The tower mount option is used to attach our enclosures to UT930, UT920, and
ATW towers. An enclosure ordered with the tower mount option will be shipped
with a three-piece bracket for fitting to the top of the enclosure and an identical
three-piece bracket for fitting to the bottom of the enclosure. This mounting
bracket option uses the same three-piece brackets as the mast mount option, except
the pieces are rearranged so that the flanges are on the side of the bracket instead
of in the middle. For the UT930 the distance between the centres of each flange
needs to be 43 cm (see Figures 7-4, 7-5, and 7-6), if mounted on the lowest section
of the tower. For other towers adjust accordingly.

Attach the enclosure to a UT930 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 centres of each

flange is 43 cm (see Figure 7-4).

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 90 cm from
the ground.

6. Use the furnished 46 mm centre 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.

7.3 Leg Base of a CM110, CM115, CM120 Tripod

The leg mount option is intended for attaching an ENC10/12, ENC12/14, or
ENC14/16 enclosure to the leg base of a CM110, CM115, or CM120 tripod. 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 the tripod (see Figure 4-7).

(1) For some tripods, the #19124 bracket may not be pre-installed
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 7-7.

(2) An ENC16/18 cannot be mounted to the leg base.

Attach the enclosure to the leg base as follows:

1. Place the flange of the tripod’s bracket into a notch in one of the enclosure’s

bracket (see Figures 7-7, 7-8, and 7-10).

2. Attach the u-bolt bracket on the other enclosure bracket (see Figure 7-9).

3. Use the furnished 70 mm centre u-bolt to secure the enclosure bracket to a

tripod leg (see Figures 7-9 and 7-10).

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.

8. Resistance to Weathering / Ageing

Regardless of the product range or the manufacturer, it is known that hot
compression moulded GRP is subject to erosion when used outdoors. Due to the
combined action of rain, wind and UV rays, the polyester matrix is superficially
eroded and glass fibres may become apparent. However, the depth of this erosion
is only 7µm.

This slight erosion is unavoidable unless a surface coating (e.g. varnish) is applied
(which brings with it additional problems such as adhesion). It is important to note
that any erosion is very superficial and has no effect on the physical
characteristics (electrical, mechanical or chemical) of the polyester.

Enclosures of the type supplied by Campbell Scientific have been successfully
used outdoors since 1958 and tests on field samples support laboratory results.
These enclosures are maintenance free.

If you wish to remove the appearance of any small surface scratches or scuffs
simply apply petroleum jelly (e.g. Vaseline) or oil to the surface and rub lightly.
Similarly any slight surface erosion due to weathering can be restored to its
original appearance by gently rubbing with fine sandpaper before applying
petroleum jelly.

As of September 2009, all enclosures will be supplied with a special
surface coating to reduce surface ageing. No extra surface treating
should be necessary unless the enclosures are exposed to extreme
environments.

Appendix A. DIN rail terminal kits

A.1 Introduction

The 006706-002 (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 pn #15920 Terminal Strips, pn #15907 End Plates, and pn #15909
Jumpers. The stoppers, terminal strips, and end plates are mounted onto the DIN­Rail 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 006706-002 DIN-Rail bracket. The 006706 DIN­Rail 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.

A.2 Installation Procedure

1. Mount the #15908 DIN-Rail Stoppers, #15920 Terminal Strips, and #15907
