ENC10/12, ENC12/14, ENC14/16, ENC16/18 1. General Description Environmental enclosures protect our dataloggers and peripherals from water and most pollutants. Our standard enclosures include the ENC10/12, 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.
ENC10/12, ENC12/14, ENC14/16, ENC16/18 ENC16/18 Internal Dimensions: Weight: Entry Seals (option “-ES”): 16” x 18” x 9” 17 lbs. (2) Large—accepts 0.236” to 0.512” cables (2) Medium—accepts 0.231” to 0.394” cables (2) Small—accepts 0.118” to 0.275” cables 1.2 Prewired Enclosures Besides our standard enclosures, Campbell Scientific offers prewired enclosures that combine flexibility with ease of use.
ENC10/12, ENC12/14, ENC14/16, ENC16/18 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 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.
ENC10/12, ENC12/14, ENC14/16, ENC16/18 NOTE 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).

Door not shown. 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).
ENC10/12, ENC12/14, ENC14/16, ENC16/18 NOTE 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). The adhesive of the cable tie tab may not stick during extremely cold temperatures or extremely high humidity.

This ENC16/18 enclosure with the “-ES” option houses the equipment commonly used in a GOES satellite system. 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 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.
ENC10/12, ENC12/14, ENC14/16, ENC16/18 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 Figures 4-4, 4-5, and 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.
ENC10/12, ENC12/14, ENC14/16, ENC16/18 The default configuration is for attaching to a UT10 tower (i.e., D = 10.25”). To attach to a UT20 or UT30 tower, move the flange sections of the bracket so that D = 17”. Flange Section Flange Section FIGURE 4-5. This exploded view shows the components of a “-TM” bracket option. FIGURE 4-6. An enclosure attached to two tower legs.
ENC10/12, ENC12/14, ENC14/16, ENC16/18 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 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).

ENC10/12, ENC12/14, ENC14/16, ENC16/18 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.

Mounting Pole Enclosure Band Screw Threads Screw Clamp FIGURE 4-14. Securing the Enclosure to a Pole 6. Pull the strap tight around the pole to determine which hole to insert the Screw Clamp at the other end of the strap. Insert the clamp into this hole. 7. Use metal shears to remove any excess strap, leaving a small amount for adjustments. 8.
ENC10/12, ENC12/14, ENC14/16, ENC16/18 5. When to Replace Desiccant The humidity indicator card or optional CS210 Humidity Sensor indicate when the desiccant needs to be replaced. CAUTION Campbell Scientific strongly suggests replacing desiccant instead of reactivating old desiccant. Improper reactivation can cause the desiccant packets to explode. If you are determined to reactivate old desiccant packets, follow one of the procedures provided in Appendix C. 5.
ENC10/12, ENC12/14, ENC14/16, ENC16/18 CAUTION 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. Properly ventilate the area while using solvent and paint. Wear safety goggles, mask, and gloves while sanding. 6.2 Primer and White Paint CAUTION 20 1. Use a rag and possibly a solvent to clean the outside of the enclosure.

Appendix B. 25458 DIN-Rail Terminal Kit B.1 Introduction The 25458 kit can facilitate wiring when many wires need to be connected to one terminal. The kit contains one 15906 5-inch DIN-Rail Mounting Bracket, two 505 screws, two 6044 grommets, and two 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.

Appendix C. Reusing Desiccant Because desiccant is inexpensive, most users replace the desiccant instead of reactivating saturated desiccant. However some customers wish to reactivate saturated desiccant. To do this, care must be taken to prevent the desiccant packets from exploding during the reactivation process. This problem is caused by using too rapid of a heating process.
