ESP-LXIVM Series Controllers
IVM-SD (Surge Device)
The IVM-SD provides surge protection for
the ESP-LXIVM controller and the 2-Wire
path.
The ESP-LXIVM controller and the 2-Wire path
must be properly surge protected and grounded.
Doing so can help prevent damage to the con-
troller and irrigation system and also significantly
reduce troubleshooting, repair time and expense.
Failure to do so could result in failure of your con-
troller and voiding the warranty.
Connect the red and black wires on the
IVM-SD to the 2-Wire Path
Connect the green wires from the IVM-SD
to the grounding rod or plate
For future troubleshooting or modifica-
tions, its is recommended to leave an addi-
tional 3 feet of 2-Wire cable stores in each
valve box location.
NOTICE
Use only WC20 splice kits for all wiring connec-
tions to the 2-Wire Path. Improper wiring can
cause serious damage to your controller or irri-
gation system.
One IVM-SD is required every 500 feet or every
15 field devices.
