Foundation Construction
1. Prepare a hole for the foundation and
wiring conduit using the minimum
recommended dimensions shown in
Figure 4.
* Refer to local electrical codes for
required depth of buried wiring .
2. Trench to the foundation site as
required for each wiring run.
3. Position straight and sweep elbow
conduit sections in foundation hole
as shown. Tape the conduit ends to
seal out dirt. Backfill soil to form a 6”
(15.2cm) foundation depth. Conduit
should not extend more than 2”
above the finished top surface of the
foundation.
4. Prepare the sides of the foundation
hole with wood forms.
5. Prepare the mounting bolt positioner
with the 5/16 x 4-1/2” bolts and nuts
(provided) as shown in Figure 3. The
threads should extend 2” (51mm)
from the top surface of the bolt
positioner.
6. Pour concrete into the formed
foundation hole. Press the mounting
bolt positioner into the concrete
until it is flush and level with the
foundation surface and aligned with
the conduit.
7. Finish the concrete with a level flat
area for the pedestal base (13” x 13”
[33cm x 33cm] for the metal pedestal
or 16” x 16” [41cm x 41cm] for the
plastic pedestal). To prevent pooling
at the base of the pedestal, add a
slight taper away from the pedestal
base contact area. Allow concrete to
sufficiently harden before continuing.
8. Remove the hex nuts from the
mounting studs. Carefully position the
controller onto the studs. Install a flat
washer and a hex nut on each stud and
tighten securely.

Earth Ground
!
IMPORTANT! The Lynx SmartHub surge
protection components cannot properly function
unless an efficient pathway to earth ground is
provided. The ground path must be as direct as
possible, without sharp bends and should not exceed
10 Ohm resistance (when measured with an earth
ground resistance device). All electrical components
throughout the irrigation system should be grounded
similarly to provide the same ground potential.
The following instructions depict one of several acceptable
earth grounding methods. Due to variables in soil
composition and terrain, the method shown may not be
suitable for your installation site. Contact your local Toro
distributor for assistance and availability of the required
earth ground resistance test instrument. Recommended
ground testers are: AEMC Instruments, model 3710
clamp-on tester, or Biddle Megger, model 250260
(or equivalent).
Procedure
1. Drive a 5/8” by 8’ (17mm x 2.5m) copper clad steel rod
into well moistened soil not less than 8’ (2.5m) or not
more than 12’ (3.7m) from the controller cabinet (see
Figure 5 and 6). The top of the ground rod should be
flush with or below ground level, and should be protected
from damage using a valve box ( A).
2. Measure the ground resistance per the instructions
provided with the ground test instrument.
• If reading is 10 ohms or less, proceed to step 4.
• If reading is greater than 10 ohms, proceed to step 3.
3. Install a 4” by 96” (10cm x 2.5m) copper ground plate.
The plate should be at least .06” thick (1.5mm) and
should have a 6 AWG x 12’ (10mm² x 4m) solid copper,
insulated wire welded to the plate. The plate should
go into a trench that is at least 30” (80cm) deep ( B
). Use ground enhancement material (GEM) per the
manufacturer’s directions.
4. Using a 5/8” (17mm) clamp or exothermic-weld fastener,
attach an 8 AWG (10mm²) solid copper wire near the top
of the ground rod.
5. Route the wire through conduit and into the controller
cabinet, avoiding wire bends of less than 8” (20cm)
radius and more than 90° ( C). Secure the wire to the
copper ground lug in the controller.
6. Measure the ground resistance again. A reading of
10 ohms or less is recommended.

Make sure the soil surrounding the ground
rod and plate remains well moistened at
all times. The addition of some form of
irrigation may be required if the controller is
installed in a non-irrigated location.

New System or New Communication Cable
Lynx Smart Modules are available in 1-station configurations.
The SmartHub pedestal and cabinet can handle up to 1000 modules or 1000 stations each. The SmartHub with Lynx
Smart Modules (LSMs) can accommodate up to two daughterboards with two output circuits. Each daughterboard
can handle up to 500 modules and stations. The modules can be connected in parallel anywhere on the two-wire
communication line connected to the station terminals. Each cable path can handle up to 250 modules and stations. Each
station can activate up to two solenoids.
It is recommended that the modules are installed in an approved valve box to provide easy access to the wiring.
Use approved splice to waterproof all connectors.
Recommended Controller-to-Module cable: 14 AWG (2.1 mm2), solid copper, jacketed 2-conductor, direct burial.
Recommended Module-to-Solenoid cable: 14 AWG (2.1 mm2), solid copper, 2-conductor, direct burial.
Burial Depth
Toro recommends that the Controller-to-Module and Module-to-Solenoid cables should have a minimum cover of 6"
(150mm). The irrigation plan may specify additional depth to be consistent with the depth of mainline or lateral pipe work
and/or soil conditioning procedures such as aeration. Installation procedures must comply with all applicable local and
national electrical codes.
• Use only wire approved for direct burial if installing the wires underground without conduit.
• All field wiring splices must be accessible to facilitate troubleshooting and/or service.
Steps:
1. Route communication cable from the controller to the station module installation location.
The maximum wire length between the controller and the module is 15,000' (4500 m).
2. Secure the communication wires to terminal 1 of the SmartHub output board. White wire onto the 1st terminal and
black wire onto the second terminal. See Figure 8.
3. Install the module in a valve box. Record the module’s address number found on the side label. This address number
identifies the station(s) that the module control.
4. Secure the communication wires to the module’s black and white wires.
Connect the black communication wire to the black module wire.
Connect the remaining communication wire (red or white) to the white module wire.
Use approved splice to properly water-proof all wire connections.
5. Route output wires from the module to the solenoid.
The maximum wire length between the module and the solenoid is 410' (125m) for 14 AWG (2.5mm2) wire.
6. Connect the solenoid wires to the module’s station wires. The station wires are color coded for easy identification.
Connect the solid red colored station wire to the red/white solenoid wire.
Connect the similar color station wire with black stripe to the black solenoid wire.
Use approved splice to properly water-proof all wire connections.
7. Connect an additional solenoid to the station wire as necessary.
Each station has a maximum load of two solenoids.
8. Repeat Steps 3–8 for additional modules.
