Connecting the Controller
There are three types of connections you must make to your ESP-MC controller:
•
connections to the field valves,
•
grounding connections, and
•
connections to the main power source.
You may also want to connect an optional sensor, which prevents watering during
rainfall or when the soil is moist.
This section of the manual contains instructions for all four types of connections.
Note:
If you are installing an ESP-SAT controller, see the ESP-SAT Installation and
Operating Instructions Manual for information about connecting the controller to the
cluster control unit.
Important:
All wiring must be installed and connected in accordance with local codes.
Connections to the Field Valves
Each valve that is controlled by the ESP-MC must have its own wire that is connected
to a numbered station terminal on the controller’s terminal strip. Each station terminal
is capable of operating two valves.
Important:
The wires you use to connect the controller to the field valves must be ap-
proved for underground use. See the Rain Bird catalog for exact wire specifications.
Important:
Do not install the valve wires in the same conduit as the wires to the main
power source.
