Installing the ZDClink Controller
Locating the Transformer
1. Locate the transformer in a well-ventilated area away from
direct irrigation spray and central to the proposed installation
site of the majority of the luminaires. The primary goal is to
minimize the length of cable runs from the transformer to
the luminaires, which minimizes voltage drop and cable size.
A common mistake is to locate the single transformer on
the service side of the house or in the garage, which might
result in excessively long cable runs to reach lighted areas.
Transformers with power cords must be located adjacent
to a 120 V, GFCI-protected exterior electrical receptacle.
If a 120 V power source is not available at the desired
transformer installation location, hire a licensed electrician
to run a dedicated 120 V, 15 A circuit to the desired location.
For international ZDClink Controller models, the previously
mentioned information applies for 230 V, 10 A circuits.
2. Test all existing receptacles with both a receptacle tester and
a digital voltmeter or amp clamp to verify proper wiring and
voltage at the receptacle.
Mounting the Transformer
Wall-Mount Installation
1. Install all transformers a minimum of 12" (30.5 cm) above the
nish grade, as measured from nish grade to the bottom of
the transformer and according to code.
2. Drill pilot holes into the mounting surface, insert anchors,
and install screws into the anchors, leaving approximately
⁄" (3 mm) of the thread exposed on the screw. Mount the
transformer on the screw.
3. Use a level and a pencil to determine and mark locations for
the bottom anchors. Remove the transformer from the wall.
Drill the anchor holes and install the anchors.
4. Place the transformer back on top of the uppermost
mounting screw. Then install the screws into the anchors at
the bottom of the transformer to secure it to the wall.
Post-Mount Installation
1. Install a pressure-treated 4" x 4" x 36" (10 cm x 10 cm x
92 cm) or larger post in concrete footing.
2. Repeat the wall-mount installation instructions (Figure 3
on page 6) without using wall anchors.
All ZDClink Controllers come equipped with a 5' (1.5 m), 12 AWG
(2.05 mm), three-prong electrical power cord. Only use the
ZDClink power cord in conjunction with a GFCI-protected, 120 V
exterior receptacle (or 230 V receptacle for international/
export version).
Note
When installing the Wi-Fi Module, consider increasing
the installation height to improve signal strength and
screen visibility.
