Safety Precaution

Danger:

Please do not privately disassemble or replace any parts of the product. Otherwise, it may cause mechanical fault, electric shock, fire or personal injuries.

Warning:

The installation and commissioning of this equipment must be carried out in accordance with the instructions. The electric construction shall comply with local laws and safety regulations.

The device can be placed on a flat surface or mounted with screws. HDL will not be responsible for any consequence caused by the inexpert or faulty installation and wiring methods, which are not in accordance with the instructions contained in this datasheet.
Please contact HDL after-sales departments or our designated service agencies for your maintenance service. Product failures caused by private disassembly are not subject to the warranty.

Caution:

Before performing any installation or disassembly procedures on the device, it is crucial to disconnect the device from all voltage sources. This step is necessary to ensure the safety of the technician and prevent any potential damage to the device.

Do not use corrosive liquid to wipe the device body, especially the interface, so to avoid damage to the device.
Before performing any maintenance or cleaning procedures on the device, it is imperative to disconnect the device from all voltage sources. This precautionary measure is necessary in order to prevent electric leakage and the risk of electric shock.

Physical connection cables: special cables for electricians.
For DALI connection, a hand-in-hand connection is recommended.

After all of the cables are terminated, check for correct and good terminations.
There are no polar requirements for DALI.
Overrange is not allowed.
Please use the device in accordance with the technical specifications.

Wiring

With DALI BUS
With 0/1~10V dimming
With PUSH dimmer

Remark: Only use open push button without indicator light. Maximum cable length between each Unit: 20 meters.

AC Push Function

Press the Push DIM (Touch DIM) switch for 8s or more,the driver can be controlled via Push DIM switch.
Short press the Touch DIM switch (<0.5s) to control the lamp on or off.
Long press the Touch DIM switch (>0.5s) to dim the brightness of light. The dimming direction will change every time after pressing switch.
Double-click the Touch DIM switch (<0.3s), then all lamps connected on the device will be set maximum brightness.
The brightness adjustment range is 1%-100%, and the light can be turned off through short pressing when doing the adjustment with long pressing Touch DIM switch.
With the Power off memory function, the power-down state will be recovered when power on again.

Installation

This product needs to be installed and commissioned by qualified personnel.
This product is not waterproof, please do not expose this product to humid environment.

Please make sure that the output voltage of the LED power supply meets the voltage range of this product.
Please make sure that the wire diameter is sufficient for the load connection of the LED fixture, and ensure that the wiring is secure.
Please disconnect the mains power supply from the circuit breaker before operating the wiring.

Ensure all wiring is correct before energising for commissioning to avoid damage to the luminaire due to incorrect wiring.
If a fault occurs, do not repair it privately, if in doubt contact the supplier.

Disassembly

WARNING: Before disassembling, please cut off the power supply, and strictly prohibit operation with electricity.

Operation

Use with controllers

For use with Buspro-DALI Controller or KNX-DALI Controller.

The DALI controller automatically assigns a DALI address code, one DALI address code can control the output of one device, please refer to the instruction manual of the DALI controller for details.
