Installation Instructions
Introduction
The OSMAC G3 controller is designed for installation on a substantial concrete foundation with embedded conduit
of various diameters to enable power, eld and earth ground wiring to be routed into the cabinet. A mounting bolt
positioner and basic mounting hardware components are included with each controller. Additional materials required to
complete the installation must be obtained separately. A material list can be compiled by reading through the instructions
completely prior to starting the installation.
CAUTION: For your protection and the safety of the product user, comply with all Caution and Warning Statements
within this document. All installation practices must comply with all applicable national and/or local electrical and
construction codes.

and wiring conduit using the
minimum recommended dimensions
shown in Figure 1.
*Note: 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 the straight and sweep
elbow conduit sections in the
foundation hole as shown. Tape
the conduit ends to seal out dirt.
Backll soil to form a 6" (15.2cm)
foundation depth. Conduit should
not extend more than 2" (51mm)
above the nished 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 1.
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 ush and level with the
foundation surface and aligned with
the conduit.
7. Finish the concrete with a level at
area for the pedestal base (13" x
13" [33cm x 33cm] for the metal
cabinet or 16" x 16" [41cm x 41cm]
for the plastic cabinet). To prevent
pooling at the base of the pedestal,
add a slight taper away from the
cabinet base contact area. Allow the
concrete to suciently harden before
continuing.
8. Remove the hex nuts from the
mounting bolts. Place the pedestal
on the pad ensuring all bolts pass
though the holes provided. Install a
at washer and a hex nut on each bolt and tighten securely.

Earth Ground Installation
Important! Toro surge protection devices require an acceptable earth ground to dissipate excess energy. An earth
ground is required in all cases, and a measured resistance of 10 ohms or less is recommended. If it is impractical to
achieve a measured resistance of 10 ohms, the installation of ground rods, ground plates, and ground enhancement
material per the grounding material manufacturer’s instructions is recommended. It is further recommended that all earth
grounds and surge protection devices be checked yearly and after each lightning event. Toro advises against the use of a
bonding/shielding wire in conjunction with Toro irrigation control systems. Grounding materials or equipment that are not
specied in these instructions should not be connected to the Toro control products, Toro communication/power wiring
or the grounding for the communication/power wiring. All electrical equipment grounds must meet local electrical codes.

1. Drive a 5/8" (16mm) by 8' (2.5m) copper-
clad steel rod into well-moistened soil not
more than 12' (3.7m) from the satellite. The
top of the ground rod should be slightly
below grade level.
2. Using a 5/8" (16mm) clamp or “Cad weld”
fastener, attach a length of #6 (6mm2) solid
copper wire near the top of the ground
rod. Avoiding sharp bends, route the wire
through the foundation into the controller
cabinet. Secure the wire to the large copper
ground lug provided on the power supply
chassis. See Figure 2.
Note: Make sure the soil surrounding
the ground rod(s) remains well moistened
at all times. The addition of some form of
irrigation may be required if the satellite is
installed in a non-irrigated location.
3. Measure the ground resistance per the
instructions provided with the ground test
instrument. If the resistance exceeds the
acceptable limit, additional ground rod(s)
can be installed at a distance equal to twice
the buried depth of the rst rod; i.e., 16'
(4.9m).
Note: A Toro Valve Cover, P/N 850-00, works well for covering the ground rod and providing access to the ground
wire connection(s).
Input Power Installation
CAUTION: When installing multiple controllers, polarity of the Line and Neutral connections must be properly
maintained throughout the irrigation system. Reversed polarity may cause damaging potentials to exist at one or more
controller locations. An equipment ground wire from the power source must also be connected to the satellite power
supply terminal block.
WARNING
AC POWER WIRING MUST BE INSTALLED AND CONNECTED BY QUALIFIED PERSONNEL ONLY.
ALL ELECTRICAL COMPONENTS AND INSTALLATION PROCEDURES MUST COMPLY WITH ALL
APPLICABLE LOCAL AND NATIONAL ELECTRICAL CODES. SOME CODES MAY REQUIRE A MEANS OF
DISCONNECTION FROM THE AC POWER SOURCE, INSTALLED IN THE FIXED WIRING, HAVING A CONTACT
SEPARATION OF AT LEAST 0.120” (3MM) IN THE LINE AND NEUTRAL POLES.
ENSURE THE AC POWER SOURCE IS OFF PRIOR TO CONNECTING TO THE CONTROLLER.

1. Place the controller’s main power switch in the O position. See Figure 3.
2. Position the input voltage select switch to the 115V (for 115-120V service) or 230V (for 230-240V service) as

Field Wire Installation
CAUTION: The OSMAC G3 controller is capable of operating up to 12 stations simultaneously when operating with
a pump, or 16 stations simultaneously without a pump. To prevent possible controller damage, total output current load
must not exceed 3.2 amps. If more than one valve per station will be connected, calculate the total in-rush current load
which would be imposed in the maximum operating conditions and use this value as a guide during installation and
operation of the controller.
Procedure
1. Attach the control and common wires to each valve and/or valve-in-head solenoid leads using an approved
waterproof splicing method. Route the wires into the controller cabinet through the 3” (76mm) conduit.
2. If an automatic pump start is required, refer to the applicable wiring diagram in Figure 5 (page 4) and install
accordingly.
CAUTION: Do not connect the pump starter directly to the controller’s pump start circuit – damage to the
controller will result.
Note: The pump circuit can also be utilized to control a master valve if required.
