• ⚠ Caution: Do not use the device in damp environments or under extreme temperatures. Improper use may result in malfunctions or damage.
• Ensure that only authorised persons have access to the device – both physically and digitally.
• Comply with applicable laws, standards and regulations during installation.
• Use the device only for its intended purpose and always follow the operating instructions.
• Only allow trained specialists to carry out maintenance work. Unauthorised intervention may compromise safety and may invalidate warranty or guarantee claims.

Electrical safety

• Disconnecting from the mains: Always disconnect the appliance from the mains before carrying out any maintenance or cleaning work to avoid the risk of electric shock.
• Insulation and cable condition: Regularly check cables and connections for damage. Defective cables must be replaced immediately.
• Moisture: Ensure that no liquids can penetrate the device to prevent short circuits.
• Only use approved power supplies and protect the device from overloads with suitable fuses.
• If necessary, plan for additional feed-in modules to avoid overloading.
• Ensure adequate earthing and secure electrical connections.
• The overvoltage protection and the power supply of the DALI bus must be ensured by qualified personnel. This is a prerequisite for safe and standard-compliant operation of the system.
• ⚠ Caution: Danger due to mains voltage on the DALI bus! The DALI bus operates with a voltage between 12V and 20.5V DC, but may be connected to the mains voltage depending on the system configuration. Please note that the DALI voltage is not classified as SELV (Safety Extra Low Voltage) in accordance with IEC 61140. Voltage potentials of up to 230V may occur! Before working on the DALI cable, always check that it is voltage-free using a suitable measuring device and disconnect the system from the power supply!

Mechanical safety

• Assembly and disassembly: Only loosen and fasten covers and fasteners with suitable tools to avoid damage and injury.
• Check the device for damage before use. Do not use it if it is defective.
• Avoid contact with electrical connections and ensure that no conductive contamination occurs.

Thermal safety

• Ventilation: Ensure that the ventilation slots and openings are not blocked. Adequate air circulation is necessary to protect the device from overheating.
• Ambient temperature: Avoid operating the device in extremely hot environments. Adhere to the temperature ranges recommended by us.
• Regular maintenance: Clean dust filters or ventilation openings regularly to prevent heat build-up.

Cleaning and maintenance

• Clean the housing only with propanol and do not use contact spray.
• Do not expose the device to harmful environments and, if necessary, install it in a protective housing.
• Replace defective products immediately.

Connections and components

In this chapter, you will learn about the most important connections and components of the Lichtwart Core. This will help you to better understand its functions and install the Core correctly.

A picture of the device with all relevant connections is shown here. The individual connections are explained below:

1. DALI PWR: This is where the DALI power supply is connected.
2. DALI: This is where the DALI bus is connected.
3. DALI status LED: The LED indicates the current data traffic on the DALI bus (bus traffic) and also signals whether the DALI bus is in test mode.
4. DALI SW: Use this button to activate or deactivate the various DALI test modes.
5. Status LED: The LED shows the current operating status and any error codes for the device.
6. Terminal 1 & 2: + 12 V power supply – terminal is looped through Terminal 3 & 4: GND 12 V power supply - terminal is looped through
7. Digital inputs terminal block 5-24: Potential-free digital inputs for receiving external signals up to 24 V.
8. Relay: max. switching with 30 V / 1 mA, max. current carrying capacity 3 A
9. Analogue inputs terminal block: For receiving external analogue 0-10 V signals.
10. RS485 RTU interface: This serial interface is used to connect to external devices or systems.
11. ANT1 4G DIV: This is where the antenna for wireless communication via the 4G network is connected (different frequency range than ANT2 4G).

Warnings for assembly and disassembly

<aside> ⚠️

</aside>

Contact with dangerous live voltage can result in electric shock.

1. Always disconnect the power supply from the system before carrying out any conversion work!
2. Use a suitable measuring device to check that the system is completely de-energised.

Install the core module on the mounting rail

1. Place the core module on the top-hat rail.
2. Ensure that the orange retaining clips are properly engaged under the top-hat rail. If this cannot be done without considerable force, you can open the retaining clips with a screwdriver and then securely fasten the core to the top-hat rail.

Connecting the power supply unit

1. Snap the power supply onto the top-hat rail.
2. Connect the 230V AC input side to the power supply.
3. Connect the 12V DC output side to terminal 1 or 2 (12V) and terminal 3 or 4 (GND) on the Core.

Connection of the DALI power supply

1. Connect the 18V DC to the designated DALI power supply terminals (Dali + and Dali -) on the Core.

Connection of the DALI bus

1. Connect the DALI bus to the designated DALI terminals on the core.
2. Ensure that the wiring is clean to guarantee stable and interference-free communication.

Disassembling the core

1. Disconnect the system from the power supply.
2. Use a suitable measuring device to check that the system is truly de-energised.
3. Remove all electrical connections from the core.
4. Unlock the retaining latch on the core to safely remove it from the top-hat rail.

Grounding or protective measures

DALI

DALI stands for "Digital Addressable Lighting Interface" and refers to a bus-compatible interface protocol that allows you to control, monitor, and individually address luminaires and other components of a lighting system.

What is the control line?

The control line is used to send digital signals, such as "dim to 50% brightness," to the lamps. The control line consists of two wires and can be laid together with the 230 V power supply line, provided that the applicable safety regulations are observed. A practical implementation for this is the use of a 5-core cable, which integrates both the two wires for the DALI control and the wires for the power supply.
