Low Voltage Transformer

Important safety information to reduce risk of fire injury.
1.Do not install within 10 feet (3 m) of a pool, spa or fountain.
2.There are no serviceable parts inside the power supply unit.
DO NOT DISASSEMBLE.
3.Do not repair or tamper with cord or plug.
4.Do not submerge transformer in water.
5.Do not mount the transformer onto combustible material.
6.Do not connect two or more transformers in parallel.
7.Do not use the transformer with a dimmer switch.
8.Plug the power supply unit directly into a GFCI wet location outlet.
9.For use with low voltage outdoor landscape lighting system only.
10.The maximum output of this transformer is 300 watts. Do not overload
the transformer. Be sure that the total cumulative wattage of all 12 volt
fixtures connected to the transformer is equal to or less than 300 watts.
SAFETY INSTRUCTIONS
The 300 Watt transformer has 300 watt circuits which will power up to 300
watts of light.To make sure the maximum number of fixtures can be safely
connected to this transformer, add up the individual wattage of all the fixtures.
The total wattage of your fixtures must not exceed output capacity of the
300 Watt transformer.
Be careful when splitting the landscape cable. Do NOT expose the copper
cable. Remove 1/2 inch of insulation from both cables and twist the ends.
- DO NOT MIX SOLID AND STRANDED TYPE WIRES IN THE SAME
TERMINAL BLOCK SCREW.
CALCULATION LIGHTING CAPACITY
1.Preparing the Cable
INSTALLATION
01
CAUTION: This landscape light system must be installed in accordance
with all local codes and ordinances. If you are experiencing problems,
contact a qualified electrician.

Lay the transformer on a flat, stable surface and use screwdriver to connect
the stripped ends of the cable under the terminal clamping plate.
2.Connecting the cable to the Transformer
This transformer has multiple output terminals: 2 x Common (COM), 12V &
15V. The total load applied to the two commons must not exceed 300VA.
Different voltage terminals can be used simultaneously as long as the total
lamp VA does not exceed 300VA. One wire of each cable needs to be
connected to a common. Make sure all unused taps (leads) are separately
insulated.
02
- Split the cable 2" and strip ½"
of insulation from wire ends.
- Insert the stripped wire ends
into the terminals.
- Tighten screws securely. SCREW
CONNECTIONS MUST BE
TIGHTENED 18lb-in.
- Plug transformer power cord into
a 120V GFCI protected receptacle
marked " wet location."
NOTE: Gently pull on the landscape cable
to verify if the connection is strong.

Lay your fixtures (not included) to your desired location. Be sure they do not
exceed the 300-watt rating of the transformer. Coil the rest of the cable after
connecting the last fixture.
3.Placing Your Fixtures and Routing the cable
Turn the transformer on. Use the cable connectors to attach your fixtures
with the cable. Then it will light up.
4.Attaching Your Fixtures
Mount the transformer directly to a solid wall surface using supplied screws
and mounting bracket with slotted holes. 12 inches to 48 inches (0.3m to
1.2m) height from the ground would be recommended.
5.Mounting the Transformer

Operating Instructions
04
Figure 1: OFF MODE
The transformer does not work, there is no output voltage, and the load
lamps will not light.
Figure 2: ON MODE
The transformer will maintain the output throughout the day, and the load
lamps will always be on.
Figure 3: AUTO MODE
In this mode, the transformer will take 30s to detect the external
environment firstly. If it is night, the transformer will start output 30s later,
then the load lamps will light on automatically and off at dawn. If it is during
the day, the transformer will have no output and the load lamps will not light.
Note: If the light emitted by the load lamps shines on the sensor at night, it
may cause the transformer to continuously switch on/off, and the load lamps
flash continuously, with a flash interval of 30s.
Figure 4 &Figure 5: COUNTDOWN MODE
In this mode, the transformer will also take 30s to detect the external
environment firstly. If it is night, the transformer will start output 30s later

TIPS:
1.When the transformer is working, the dot in the lower right corner of the
display lights up. If the dot is not light up, it means that the transformer
has no output voltage.
2.The transformer has a power-off memory function. After the transformer
has been working in the current mode for 24 hours, the transformer will
remember the current working mode. When the transformer powers on
again, the transformer will enter the working mode before the power failure.
3.The display shows "F"
Step 1: Unplug the transformer from the power outlet.
Step 2: Check if the transformer is overloaded.
Step 3: Check if there is a short circuit at the transformer terminals.
Step 4: Check whether the connection between the lamp and the buried
wire is short-circuited.
Step 5: After troubleshooting, replug the transformer, it will automatically
reset.
4.In ON mode, the load lamp is off, the display shows "0"
Step 1: Unplug the transformer from the power outlet.
Step 2: Check if the transformer terminals are properly connected.
Step 3: Check whether the connection between the lamp and the buried
wire
Step 4: After troubleshooting, replug the transformer, it will automatically
reset.
5.In AUTO mode or COUNTDOWN mode, the load lamp does not light,
the display shows "A" or "N" (N is the selected timing time).
Step 1: Unplug the transformer from the power outlet.
Step 2: Check if the transformer terminals are properly connected.
and the load lamp will light. Then it will turn off automatically when the
the countdown is over. If it is during the day, the transformer will have no
output and the load lamps will not light.
Note: When the system starts to count down, if the surrounding light shines
on the sensor for more than 30s, the countdown will end, the transformer will
stop output, and the load lamp will go out.

Step 3: Check whether the connection between the lamp and the buried
wire is correct.
Step 4: After troubleshooting, replug the transformer into the power outlet.
Step 5: Press the up/down button to enter AUTO mode or COUNTDOWN
mode, cover the sensor for more than 30s, the load lamp will light up.
