4. Installation Guide

4.1 Unboxing Inspection

• Check the package contents: SLX-GW-DL_C2, installation accessories, and other necessary components.

• Inspect the product appearance for damage.

4.2 Installation Environment Requirements

• Ambient Temperature: -20℃ to 55℃.

• Ambient Humidity: 10% ~ 90% RH (no condensation; do not install in humid environments such as flooded areas of basements).

• Installation Location: Keep away from heat sources, avoid direct sunlight, and stay clear of strong electromagnetic interference sources (e.g., frequency converters, high-power motors, high-voltage cables) with a minimum distance of ≥ 1 meter.

• Installation Method: Only supports 35mm standard DIN rail mounting.

• Rail Thickness: 1.0 ~ 1.5mm; the bayonet must be securely fastened during installation.

• The length of the RS-485 bus shall not exceed 800 meters.

4.3 Power Supply and Cable Adaptation Requirements

4.3.1 Power Supply Adaptation Requirements

SLX-HT must use a DC 24V power supply that meets the following parameters:

• Output Voltage: DC 24V (allowable range: 22.8V - 25.2V);
• Rated Power: ≥2W (to avoid device restart due to insufficient power supply);
• Power Supply Type: AC/DC adapter or switching power supply complying with safety standards;
• Interface Matching: Must be used with 2-pin plug-in terminal blocks (pin spacing 5.08mm). Gold-plated terminals are recommended to reduce contact resistance.

4.3.2 Cable Selection Requirements

Cables for different interfaces shall be selected in accordance with the following specifications to avoid signal interference or transmission failures:

Interface Type	Cable Specification Requirements	Maximum Transmission Distance	Additional Requirements
RS485 Interface	Twisted pair shielded cable (RVSP 2×0.75mm²)	≤1200 meters	The shield layer shall be single-ended grounded (ground resistance ≤4Ω)
DALI	1.50 mm^2 Conventional Cables	≤300 meters	Do not use Ring wiring or Mesh wiring.
USB	Standard copper cable (AWG28-24 gauge)	≤5 meters	The cable shall include four cores: D+, D-, VCC and GND; Shielded cables shall be used for lengths exceeding 3 meters

Note: For detailed technical parameters (such as power supply parameters, RS485 technical parameters, etc.), refer to the 《SLX-GW-DL_C2 datasheet》.

4.4 Installation Steps and Wiring Instructions

1. Select the installation location: ensure compliance with environmental requirements.

2. Mount the sub master converter on the guide rail.

   

   install

3. Connect the RS-485 interface of the host or master converter to the RS-485 interface of the sub converter via the RS-485 bus.

   

   485_connect

4. Set the RS485 slave address of the sub converter via RS485 address encoders.

   

   address_switch

• :warning: On the same RS-485 bus, the RS-485 slave addresses of all sub converters must not be duplicated.

• :warning: The RS-485 slave address must not be set to 0.

6. Connect the DALI cable to the DALI lamps.

7. Connect the output interface of the power supply to the master converter's power supply port.

6. Testing and Verification

This product is a DALI 2-channel sub converter component in the SafeLUX system, therefore it needs to be used in conjunction with the SafeLUX system host.Or connect the sub converter to the master converter via the RS-485 bus to expand the number of DALI channels of the master converter.

After adding a converter to the SafeLUX system, you can control the converter and the DALI lamps mounted under the converter DALI bus on the SafeLUX system page.

For more information, please refer to the SafeLUX host user manual, SafeLUX system user manual, and other related documents.

Basic Verification Steps(Connect the sub converter to the host):

1. Hardware connect

2. Power on the system

3. Log in to the host system

4. Access the device management page

5. Add the sub converter (Add sub converter via 485 Bus)

6. Perform other operations

Basic Verification Steps(Connect the sub converter to the master converter):

1. Hardware connect

2. Power on the system

3. Log in to the host system

4. Access the device management page

5. Add the master converter (Add master converter via network)(If the host and the master converter are on the same local area network (LAN), automatic converter addition is available)

6. Expand the DALI bus of the master converter(If it is a newly added master converter, it will automatically scan for sub converters during the addition of the master converter to expand the DALI channels.)(If a new sub converter is added to the RS-485 bus of the master converter that has already been added to the system, it is necessary to manually perform the operation of expanding DALI channels on the page.)

7. Perform other operations
