2.2 Battery Installation
Install the batteries as follows:
(For units manufactured prior to September 2018, refer to Appendix I.)
1) Open the device by unscrewing the four captive screws on the front of the enclosure. Make
sure that no dirt, water or other contaminants are allowed to enter the enclosure.
2) Install the batteries by aligning the positive (+) side of the D cells with the left side of the
battery holder. Push the batteries straight down into the holder.
3) The battery select switch (located to the right of the battery holder) is set to "Alkaline" at the
factory. If using lithium batteries, move the switch to the "Lithium" position.
2.3 Accessories
After the batteries have been installed:
1) Remove the desiccant packs from the plastic seal top bag they were shipped in and place
them inside the enclosure.
2) Reinstall the cover. Ensure that the rubber gasket clean and properly seated in the groove on
the underside of the cover. Tighten the screws a little at a time, working in a diagonal pattern.
Make sure the cover seals tightly and evenly.
2.4 Earth Ground Installation
The LC-2x4 provides lightning protection in the form of gas tube surge arrestors. In order for
these components to divert the energy from a lightning strike safely to ground, a good solid
electrical connection to earth ground needs to be made. A grounding rod should be driven (or
other suitable attachment to earth utilized) to ground the system and provide a path to earth in the
event of a lightning strike. A 6' to 8' copper stake with appropriate large gauge wire (12 AWG or
larger) connected to the LC-2x4 enclosure is suggested. The stake should be driven as close to
the datalogger as possible, and to a depth of at least one meter (three feet). A copper grounding
lug is supplied on the exterior of the LC-2x4 enclosure to provide connection to this wire from
the grounding rod.
