Cabinet Installation

Selecting the proper installation site for the GDC is essential to safe

and reliable operation. The GDC features a weather resistant cabinet designed for indoor or outdoor installation.

The GDC 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, install the GDC 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 GDC 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.

Power Source Installation 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.

Station Decoder Installation The station decoder module is available in 1-station, 2-station or 4-station configuration. The decoder modules are installed into the GDC output board terminals. The GDC model can handle up to 100 stations per output board. These stations can be connected to the output board terminals in any configuration (25 stations connected to each of the four terminal pairs or 100 stations connected to one terminal pair, etc.).

Grounding Communication Cable IMPORTANT! Cable Splices: In order for the wire connections to comply with the 2005 edition of the National Electric Code® Article 300.5 (Underground Installations) and 110.14 (Electrical Connections), in wet or damp locations, the connector must be listed under specification “UL 486D” if installed in a valve box. It must be listed under specification “UL 486D-Direct Burial” if buried in dirt.

Lithium Battery Replacement A 3.9V Lithium battery (P/N 363-2200) is installed in the timing mechanism to sustain the controller’s clock time and date for approximately 10-years with no additional power applied. WARNING! DANGER OF EXPLOSION IF BATTERY IS INSTALLED INCORRECTLY. REPLACE ONLY WITH THE SAME OR EQUIVALENT TYPE OF BATTERY. ALWAYS DISPOSE OF USED BATTERIES ACCORDING TO THE MANUFACTURER’S INSTRUCTIONS. Step 1 – Place the controller’s power switch to OFF.
