2 SAFETY
Avoid potential electrical faults when wiring the DT2306 data logger.
Do not wire the DT2306 data logger in a lightning storm.
The DT2306 data logger uses a 3.6 V lithium-thionyl chloride battery. Standard
batteries (defined as SAFT LSH 20 D-cell, or equivalent) are used for radio-enabled
loggers and compact batteries (defined as either one SAFT LSH 14 light C-cell
battery, two SAFT LS 14500 AA batteries, or equivalent) are used for stand-alone
data loggers. For more information about batteries, please see Section 6.
CAUTION:
DO NOT ATTEMPT TO RECHARGE THE BATTERY.
DO NOT REPLACE THE BATTERY WITH AN ALKALINE OR ZINC-CARBON BATTERY.
REMOVE STANDARD BATTERIES PRIOR TO SHIPPING THE DT2306.

3.3 POTENTIOMETER CONNECTION
There are five cable glands on the exterior of the DT2306 logger. The following
instructions detail the steps necessary to loosen the glands and insert and connect
the cable.
CAUTION:
AVOID OPERATIONS WITH THE LOGGER COVER OFF IN RAIN OR SNOW.
DO NOT ALLOW RAIN OR SNOW TO ENTER THE ENCLOSURE.
DO NOT INSTALL IN FLOODABLE LOCATIONS.
THE LOGGER IS RAIN-TIGHT ONLY AND NON-SUBMERSIBLE.
NOTE: THE PICTURES IN THIS SECTION ARE INSTRUCTIONAL AND MAY FEATURE A
LOGGER OTHER THAN THE DT2306 TO ILLUSTRATE THE INSTRUCTIONS.
1Loosen the cable gland using two 20 mm wrenches. Hold the bolt in place with
one wrench. Loosen the cap with the other wrench. Refer to Figure 3-1 for proper
wrench placement.
Refer to Figure 3-2 for the cable gland nut wrench placement.
CAUTION: ENSURE THE ENTIRE NUT BODY DOES NOT LOOSEN.LOOSEN ONLY THE
GLAND.

2Remove the black cable plugs from the cable glands. Refer to Figure 3-3.
FIGURE 3-3 REMOVE THE CABLE PLUG FROM THE CABLE GLAND
3Loosen the 4 Phillips screws on the top of the logger. Lift the cover off.
4Insert the sensor cable with stripped wire ends through the cable glands and into
the logger. Ensure the cable sheathes are inside the enclosure.
5Connect the leads. Refer to Figure 3-4.
CAUTION: ENSURE NO BARE WIRES ARE VISIBLE.

6Secure the wires to the logger circuit by tightening each wire with a 2.5 mm flat-
blade screwdriver.
7Tighten the cable glands using the same wrench positioning as step 1. Refer to
Figure 3-5. Tug gently on the cable after each half turn to inspect cable mobility.
FIGURE 3-5 TIGHTENING THE CABLE GLAND

8Perform a final half turn once the cable is immobile. Do not overtighten or under
tighten cable glands.
CAUTION:
OVERTIGHTENING THE CABLE GLAND COULD DAMAGE THE CABLE.
UNDER TIGHTENING THE CABLE GLAND COULD CAUSE A LEAKAGE AND WATER
DAMAGE.
9For a stand-alone data logger, insert the battery into the battery adapter (see
Section 6 for information regarding the types of batteries suitable for this logger).
Place the adapter into the battery holder.
For radio-enabled loggers, place the battery into the battery holder. Roll the
battery back and forth to clean the contacts.
If the batteries are already installed, hold the battery in place and pull the tab out
to activate the logger. Refer to Figure 3-6.
FIGURE 3-6 ACTIVATE THE BATTERY
10 Replace the cover. Loosely tighten each screw in the X pattern as shown in
Figure 3-7. Then securely tighten each screw in the X pattern.
