Cabinet Installation

Selecting the proper installation site for the 2-wire decoder is essential to safe
and reliable operation. The 2-wire decoder features a weather resistant cabinet designed for indoor or outdoor installation.

The TDC should be installed on a vertical wall or other sturdy structure near
a grounded power source. Select a location that shades the controller during the
hottest hours of the day and provides as much protection from direct sunlight,
rain, wind and snow as possible. DO NOT mount the controller where it is
exposed to direct spray from the irrigation system.

For easy operation and better view of the display (Stand-alone model),
install the TDC so that the display is at or slightly below eye level.

Step 1 – Drill two pilot holes 15.25cm apart for the top keyholes of the

controller cabinet.

Step 2 – Install the top screws leaving approximately 5–6mm of exposed

screw to accommodate
the cabinet.

If mounting the cabinet on dry wall or
masonry, install the appropriate type of screw
anchors or fasteners to ensure secure installation.

Step 3 – Hang the cabinet using the top keyhole slots.

See Figure 1.

Step 4 – Open the cabinet door and install the bottom two

screws to
secure the cabinet.

Earth Ground Installation

IMPORTANT! The TDC 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 must not exceed 30 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.

Step 1 – Drive a 5/8" x 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. The top of the ground rod should be 12" (30.5cm) below grade level.
See Figure 2.

Step 2 – Using a 5/8" (17mm) clamp or “Cad weld” fastener, attach an 8 AWG (8mm

2

) solid copper wire near the top of the

ground rod. Avoiding wire bends of less than 8" (20.3cm) radius and more than 90

o

, route the wire through conduit

and into the cabinet. Secure the wire to the copper ground lug.

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 cabinet is installed in a non-irrigated location.

Step 3 – Measure the ground resistance per the instructions provided with the ground test instrument. A reading of

0.0 Ohm is optimum, up to 10 Ohm is good and 11–30 Ohm is acceptable in most cases. 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
first rod; i.e., 16' (4.9m). Interconnect the ground rods using 8 AWG (8mm

2

) solid copper wire and test again. If the
measured ground resistance continues to read above the acceptable limit, contact your local Toro distributor for
further assistance and recommendations.

Installing a round valve box over the ground rod enables the ground rod to be easily located as well as

providing access to the ground wire connection(s).

Power Source Installation

Step 1 – Turn off the power at the power source location and

place the controller’s power switch to OFF. Connect and
route the appropriate size 3-conductor cable (10 AWG
[2.5mm

2

] maximum) from the power source to the

controller cabinet.

The provided power cable access hole can
accommodate a 1" (25mm) conduit fitting. If conduit is
required, install a section of flexible 1" (25mm) electrical
conduit from the power source conduit box to the
cabinet’s access hole.

Step 2 – Open the cabinet door and remove the two retaining

screws from the power supply cover.

Step 3 – Locate the voltage cable assembly and note the voltage

on the label. The TDC is equipped with 120V cable
assembly from the factory. Replace the voltage cable
assembly with the proper rating as necessary. See

Figure 3.

Step 4 – Strip the power cables and secure them to the terminal

block. Reference Table 1 for the appropriate type of
power connection.

Step 5 – Reinstall the power supply cover.

Step 6 – Apply power to the controller.

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 3mm IN THE LINE AND NEUTRAL POLES.

ENSURE THE AC POWER SOURCE IS OFF PRIOR TO SERVICING. FAILURE TO COMPLY MAY RESULT IN SERIOUS
INJURY DUE TO ELECTRICAL SHOCK HAZARD.
