WARNING:
The ESP-LXME controller 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.
Ensure that all grounding devices are compliant with local electrical
codes.
Connect Power Source
The ESP-LXME controller has an internal transformer that reduces supply
voltage (120 VAC in U.S. models; 230 VAC in international models; 240
VAC in Australian models) to 24 VAC. You will need to connect power
supply wires to the transformer’s three wires. (Line, Neutral, Ground)
