2. Setup and Installation

2.1. Physical Installation

The LM-100-24-U2D2 driver features a clamshell design with screwless strain-relief. The dismountable end cap allows for adjustment of the housing length as needed. Ensure the driver is installed in a suitable environment, protected from moisture and extreme temperatures.

Figure 2: Protective Housing Application and Removal. This diagram illustrates how to secure the tension plate to fix electric wires, push the side plate outwards to remove the tension plate, and pull the housing left and right from the bottom to remove it for wiring access.

1. Secure Wiring: Push the tension plate down to firmly fix the electric wires.
2. Access Housing: To open the housing, push the side plate outwards and simultaneously remove the tension plate by prying it up with a tool.
3. Remove Housing: Pull the housing left and right from the bottom to fully remove it for internal access.

2.2. Wiring Diagram

Proper wiring is crucial for safe and correct operation. Always ensure power is disconnected before performing any wiring. The driver supports both DALI connection and Push DIM/CCT connection.

Figure 3: DALI and Push DIM/CCT Wiring Diagrams. This image displays two main wiring configurations: one for DALI connection showing N, L, DALI, and LED outputs, and another for Push DIM/CCT connection detailing N, L, Push DIM, Push CCT, and LED outputs. Wire diameters and strip lengths are specified for each connection type.

2.2.1. DALI Connection

• Connect the AC input (N, L) to the driver.
• Connect the DALI control lines to the DALI terminals.
• Connect the LED output (CCT: 2700-6500K) to the LED fixture.
• Ensure wire diameter is 0.75-1.5 mm² and strip length is 8-9mm for input/DALI.
• Ensure wire diameter is 1.5-2.5 mm² and strip length is 6-7mm for LED output.

2.2.2. Push DIM/CCT Connection

• Connect the AC input (N, L) to the driver.
• Connect the Push DIM and Push CCT control lines.
• Connect the LED output (DIM: 0-100% dimming range, CCT: 2700-6500K) to the LED fixture.
• Push DIM is invalid under DC voltage input.
• Dimming interface priority: DALI first, then Push DIM/CCT.
• Ensure wire diameter is 0.75-1.5 mm² and strip length is 8-9mm for input/Push controls.
• Ensure wire diameter is 1.5-2.5 mm² and strip length is 6-7mm for LED output.

Important: The driver is a constant power device. When ordering, ensure the constant power LED fixture is 100W. For example, a 100W driver can connect to 100W x 2CH LED strip, but the total power of the 2 channels will be kept within 100W.

3. Operating Instructions

The LM-100-24-U2D2 LED driver offers flexible control options for dimming and color temperature adjustment, primarily through DALI-2 or Push DIM/CCT interfaces.

3.1. Push DIM/CCT Control

When using a Push DIM/CCT switch, the following operations are available:

• DIM (Brightness Control):
  • On/Off Control: Short press the DIM switch.
  • Stepless Dimming: Long press the DIM switch.
  • Brightness Adjustment: With every other long press, the brightness level will adjust in the opposite direction.
  • Memory Function: The driver remembers the last brightness level adjusted when lights are turned on.
• CCT (Color Temperature Control):
  • Color Temperature Adjustment: Long press the CCT switch.
  • Directional Adjustment: With every other long press, color temperature will adjust in the opposite direction.
  • Memory Function: The driver remembers the last color temperature adjusted when lights are turned on.

Figure 4: Push DIM/CCT Switch Operation. This section of the image illustrates the functions of a Push DIM/CCT switch, detailing short press for on/off, long press for stepless dimming and color temperature adjustment, and memory functions for both brightness and color temperature.

3.2. DALI-2 Control

The LM-100-24-U2D2 is compatible with DALI-2 control systems, allowing for advanced control over dimming and tunable white (DT8) functionalities. Refer to your DALI-2 control system's manual for specific programming and operation details.

4. Maintenance

The LM-100-24-U2D2 LED driver is designed for reliable operation with minimal maintenance. However, periodic checks and proper handling are recommended.

4.1. General Care

• Keep the driver clean and free from dust accumulation.
• Ensure adequate ventilation around the driver to prevent overheating.
• Avoid exposing the driver to direct sunlight, high humidity, or corrosive environments.

4.2. Housing Removal for Access

If internal access is required for inspection or wiring adjustments, follow the steps outlined in Section 2.1 for safe housing removal. Always disconnect power before opening the unit.

5. Troubleshooting and Safety Precautions

This section provides general precautions and advice for addressing common issues.

5.1. Important Considerations

• Professional Installation: Products should be installed by qualified professionals.
• Outdoor Use: For outdoor installations, ensure the unit is mounted in a waterproof enclosure.
• Compatibility: Use only with compatible LED fixtures and wiring. Refer to product parameters.
• Wiring Integrity: The diameter of wire used must be able to load the light fixtures you connect and ensure firm wiring.
