Mounting the Enclosure
1. Using the latch at the bottom of the enclosure, open the module.
2. Using the below template as a guide, mount the enclosure to the wall using 3/16 inch diameter
screws.
NOTE: Refer to the Agri Alert 128 manuals and quick start guide for more information on
configuration.
Grounding the System
A correctly grounded unit provides protection to the electronic components from damages caused by light-

purpose.
What You Should Know
IMPORTANT: If you are using outdoor connections, mount the enclosure as close as possible to the entry
point of the outdoor wiring.
1. Drive the clean metal grounding rod at least 10 feet (3 meters) into the ground. If the bedrock is more
