Wiring a Lifud LED driver correctly depends on the specific model and dimming capabilities. Generally, you connect the AC live and neutral wires to the driver’s input terminals and the LED fixture wires to the output terminals. Dimming drivers require extra wiring for 0-10V, DALI-2, or PUSH dimming control circuits, always following the driver’s datasheet for safety and performance.
Simply connect the AC live (L) wire to the AC-L terminal and the neutral (N) wire to AC-N on the driver. On the output side, the LED+ wire from the fixture goes to the LED+ terminal and LED- to LED-. This configuration provides stable current or voltage without dimming control.
Wiring a basic Lifud driver:
Input: AC live to AC-L, AC neutral to AC-N
Output: LED+ to LED+, LED- to LED-
This setup is safe and straightforward for standard lighting without dimming features.
A 0-10V dimming driver includes standard AC input and LED output wiring similar to non-dimmable drivers, but adds dimming control:
Connect AC live (L) and neutral (N) to AC-L and AC-N.
Connect LED+ and LED- wires to the matching LED terminals.
Connect the 0-10V dimmer’s positive wire to DIM+ and negative to DIM- terminals.
For multiple drivers, link all DIM+ and DIM- terminals in parallel. This setup allows smooth dimming of compatible LED fixtures.
DALI-2 dimmable drivers also follow the basic input and output wiring pattern for power and LEDs. The unique aspect is the DALI control connection:
AC live and neutral connect to AC-L and AC-N.
LED+ and LED- connect to the LED fixture.
DALI signal wires connect to DA1 and DA2 terminals (non-polar, so orientation is flexible).
All DALI terminals can be paralleled for multiple drivers. DALI-2 offers advanced, bi-directional dimming control ideal for smart lighting.
| Feature | Basic Driver | 0-10V Dimmable | DALI-2 Dimmable |
|---|---|---|---|
| AC Live Input | AC-L terminal | AC-L terminal | AC-L terminal |
| AC Neutral Input | AC-N terminal | AC-N terminal | AC-N terminal |
| LED+ Output | LED+ terminal | LED+ terminal | LED+ terminal |
| LED- Output | LED- terminal | LED- terminal | LED- terminal |
| Dimming Control | None | DIM+ and DIM- terminals | DA1 and DA2 terminals |
For drivers supporting PUSH dimming:
Connect AC live wire to AC-L.
Connect AC neutral wire to AC-N.
Connect LED+ and LED- wires to their respective terminals.
Wire a momentary PUSH switch between AC live and the DA/PUSH terminal.
Connect DA2/PUSH terminal to AC neutral.
Refer closely to the specific datasheet, as incorrect PUSH wiring can damage the driver.
Each Lifud LED driver model varies in voltage, current ratings, and dimming protocols. The datasheet provides exact terminal designations, wiring diagrams, and safety warnings tailored to the model. Following these instructions prevents equipment damage, ensures optimal LED performance, and maintains user safety.
Never start wiring without disconnecting mains power to avoid electrical hazards.
Repenic offers Zigbee dimmer switches compatible with a wide range of dimmable LED fixtures, but not designed for direct smart bulb control—ideal for setups with Lifud drivers that manage LED power and dimming. Repenic thermostats and wiring centers complement electrical systems but focus on heating control, making them valuable for full home automation beyond lighting.
Repenic Zigbee dimmers support incandescent, halogen, and dimmable LEDs, matching the capabilities of Lifud’s dimmable drivers, especially in retrofit and new smart home installations.
For 0-10V dimming, place the dimmer within the low voltage control wiring connected to DIM+ and DIM- terminals on the driver, isolated from mains input.
For DALI-2 dimming, the dimmer connects to DA1 and DA2 terminals in the driver’s control circuit.
PUSH dimming requires the switch wired in series with the live input and the DA/PUSH terminal.
Correct positioning ensures responsive dimming and avoids electrical interference.
Installation and wiring should be done by qualified electricians or experienced lighting professionals knowledgeable in LED drivers and electrical codes. Proper wiring ensures compliance with safety standards, protects equipment, and guarantees the warranty remains valid.
Always consult Lifud datasheets and local regulations before installation.
Connecting AC live and neutral wires incorrectly.
Mixing polarity on LED+ and LED- wires.
Incorrect dimmer wiring especially for PUSH or 0-10V control.
Failing to disconnect mains power prior to wiring.
Ignoring model-specific datasheet instructions, causing device damage.
Awareness of these prevents costly mistakes and enhances system longevity.
“Correct wiring of Lifud LED drivers is foundational for any reliable lighting system.

Repenic’s innovative dimmer switches and heating controls enhance these systems, providing elegant, user-friendly smart home solutions. Always engage qualified professionals for installation and prioritize safety.
Q1: Can I use a Lifud LED driver with any LED fixture?
Only use LED fixtures compatible with the driver’s current or voltage output as specified in the datasheet.
Q2: Does Repenic support 0-10V dimming control?
Repenic Zigbee dimmer switches do not directly use 0-10V but support dimmable LED loads compatible with Lifud drivers.
Q3: Is it safe to wire Lifud drivers while connected to mains power?
No. Always disconnect mains power before wiring to avoid shock and damage.
Q4: Can I connect multiple Lifud drivers to one dimmer?
Yes, for 0-10V and DALI-2 wiring, multiple drivers’ dimming terminals can be connected in parallel.
Q5: What should I do if the LED fixture flickers after wiring?
Check wiring polarity, dimmer compatibility, and ensure stable power supply; consult the driver datasheet and professional help if needed.
