ESP-LXD 2-Wire Decoder Control System Installation & Troubleshooting Guide

Wire Splices
Use only 3M DBR/Y-6 splice kits for all electrical wiring connections to the 2-wire path. Improper
wiring can cause serious damage to your controller or irrigation system.
Grounding & Surge Protection
The ESP-LXD 2-Wire Decoder 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.
To comply with proper installation specifications, the following components should be grounded:
ESP-LXD 2-Wire Decoder Controller
ESPLXD-M50 2-Wire Decoder Module
LSP-1 Lightning Surge Protector
SD-210 Sensor Decoder
FD-401 Field Decoder
FD-601 Field Decoder
Notes:
1. Each installed grounding system shall maintain a maximum ground resistance of 10 ohms,
or less.
2. Refer to the Rain Bird Grounding Recommendations document for proper specifications on
Grounding System Installation and Grounding System Design.
ESP-LXD 2-Wire Decoder Controller
TThe ESP-LXD 2-Wire Decoder Controller is protected against electrical surges through the ground
provided by the primary ground of the incoming power to the controller.
ESPLXD-M50 2-Wire Decoder Module
The ESPLXD-M50 2-Wire Decoder Module provides a ground lug on the front of the module that
accepts a #6 AWG Bare Copper Wire that is connected to a ground rod or plate.
A grounding wire on the module should be connected to the ground (GND) spade connector on the
small terminal strip above the transformer. It is not necessary to connect this ground lug to an earth
ground.
