125 ESP-LXD Controller
Surge Protection and Grounding
b c
WARNING: The ESP-LXD controller and the 2-Wire path must
be properly surge protected and grounded. Doing so can help
prevent damage to the controller and irrigation system and also
significantly reduce troubleshooting, repair time and expense.
Failure to do so could result in failure of your controller and
voiding the warranty.
Rain Bird requires the 2-Wire path to be surge protected and grounded
with one LSP every 500 feet or every 8 decoders, whichever is smaller.
Ensure that all grounding devices are compliant with local electrical
codes.
Install Lightning Surge Protectors (LSP-1s)
A
Using a design drawing or as-built diagram for your installation
system, determine the number of LSP-1s required and where they
will need to be installed.
B
At the first LSP-1 location, install a grounding device, typically
a grounding rod or plate, which meets all local codes, near the
2-Wire path.
C
Splice the blue wires from a Rain Bird LSP-1 to the 2-Wire path in
the same manner as the installation of a field decoder detailed
above, completing the splices with an approved direct-bury
splice kit.
D
Connect the ground wires from the LSP-1 to the grounding device
and install the LSP-1 inside a valve box.
E
Repeat this process to install all other LSP-1s as needed, noting
their locations on your as-built diagram and/or design drawings.

NOTE: LSP-1s do not have decoder addresses, so it’s not necessary
to capture this information from your LSP-1s. For this reason, LSP-
1s also do not have peel-off barcode labels for the Programming
Guide. LSP-1s do not need to be recognized by or programmed
into the controller or noted on the Programming Guide.
