Dewenwils Low Voltage Transformer

Warning

All wiring and installation must be in accordance with local building and electrical codes. Always disconnect transformer from power source before performing work on lighting system. Calculate lighting capacity correctly - total load of fixtures may not exceed 300VA.

1. Disconnect from power source prior to opening the case.
2. Do not use the transformer with an extension cord.
3. Make sure all unused taps (leads) are separately insulated.
4. Do not install within 5 ft of a pool or spa.
5. Do not exceed total fixture load of 300VA.

Product Layout

The transformer unit features mounting brackets at the top, a circuit breaker, a ground terminal, a high voltage wiring compartment, and a low voltage wiring compartment.

Installation

1. Turn off the main circuit.
2. Remove the metal cover using a screwdriver (NOT included). Take out the mounting brackets, screws, and anchors inside. [See Figure 1]
3. Unscrew the top and bottom screws on the back of the transformer. Install the mounting brackets and tighten the screws again. Pay attention to the correct orientation of the mounting brackets during installation. [See Figure 2]
4. Use screws and anchors to fix the transformer on the wall, at least 1 foot above the ground, ensuring the wiring compartments face downwards. [See Figure 3]
5. Connect the Black Wire and White Wire of the High Voltage Wiring Compartment to your live and neutral wires separately using electrical tape. Place these connected wires in the High Voltage Wiring Compartment. [See Figure 4]
6. Use the included wiring caps to connect the output line of the transformer with your load input line. Place the connected line in the Low Voltage Wiring Compartment. [See Figure 5]
7. If the load has a ground wire, connect the ground wire to the Ground Terminal.
8. Do not remove the terminal block of the unused output line port, as it may cause a short circuit.
9. Turn on the main circuit.
10. Use a screwdriver to install the metal cover on the front of the transformer. [See Figure 6]

Circuit Breaker

If a circuit breaker occurs, immediately disconnect the transformer from the power source. Common causes for a circuit break include:

• Low voltage wires incorrectly connected to transformer output terminals.
• Overload or short circuit (bare wires touching) occurring along the cable.
• Fixtures incorrectly installed along the cable.
• Lamp load along a circuit exceeding 300VA.

Make all necessary repairs to the lighting system before reconnecting the transformer to the power source. After the problem has been identified and resolved, reset the breaker by flipping the Circuit Breaker.
