3 DIN-LINK Modules The DIN-LINK is used to communicate with four types of modules: DIN-4T, DIN-8S, DIN-4C and DIN-DLI. Each DIN-LINK module is connected via the DIN bus. The DIN-LINK has a maximum capacity calculated in DIN Power Units (DPU). The maximum DPU per DIN-LINK is 64. Device Description Diagram DPU Four-channel trailing-edge dimmer module. It is suitable for controlling DIN-4T 8 mains dimmable loads. Eight-channel relay DIN-8S module for on/off 8 switching. A four-channel curtain and DIN-4C blind controller module. 8 Multi-room DALI DIN-DLI Controller 16 DIN-8S Instruction Manual | Page 5 Manual Version 1.0.2

4 Installation Instructions The overall safety of any system incorporating this equipment is the responsibility of the assembler of the end system. A qualified electrician must install the DIN module. Ensure all wiring follows local electrical standards. Use only appropriately rated cables, and secure all connections before powering on. The DIN module must be connected to a mains supply that includes appropriate protective devices. Failure to comply with these requirements may result in damage to the equipment, risk of fire, or electrical hazards. Pull down the DIN clamp 1 at the bottom of the unit to unlock it. Once unlocked, place the 2 DIN-8S over the DIN rail. DIN-8S Instruction Manual | Page 6 Manual Version 1.0.2

Push the clamp tab up to 3 lock the DIN-8S to the DIN rail. Connect the DIN-8S to the 4 DIN bus using the screw terminals located on the top left of the DIN module. Connect the loads to the 5 output terminals. L - Permanent Feed SW - Switched Live DIN-8S Instruction Manual | Page 7 Manual Version 1.0.2

5 Servicing the DIN-8S The DIN-8S contains no user-serviceable parts; should the unit require a repair, it must be returned via the online form at https://returns.rakocontrols.com/contact/service-returns/ . If the DIN-8S has been returned from a repair, ensure it is operating correctly by testing the following: Check that the input voltage matches the required specifications to ensure proper operation of the unit. Use the override buttons to switch the outputs on and off. After each switch, test the voltage outputs to confirm they are functioning as expected. Ensure that the correct box number is set on the unit as per the configuration to ensure the correct identification within the system. Verify the communication functionality by testing the unit with either a Keypad or Rasoft Pro software. 6 Programming the DIN-8S The DIN-8S is programmed using the Rasoft Pro programming software. A WK-HUB is required for any programming of a Rako Wired DIN system. Instructions for this can be found in the Wired System Setup Guide . 7 LED Diagnostics 7.1 Display DIN modules use a seven-segment display for diagnostic information.

Bootloader When the DIN module is updating firmware, the device will be put into bootloader. Bootloader Sleep Once a firmware update has commenced, the bootloader will enter Bootloader Sleep and wait for the upgrade to complete. Local Channel When receiving data from the DIN-LINK, the DIN module will flash ‘L.’ when receiving a command. Error When the test button is pressed, and there is an error communicating with the DIN module, ‘E’ will appear on the display. 7.2 Output LEDs Pattern Cause LED Description The channel is in Slow Flash ~1 seconds 1 to 8 bootloader; this occurs Bootloader (Channel Specific) during the firmware upgrade process. The DIN module's temperature is Fast Flash ~0.25 seconds 1 to 8 monitored; if the Overtemperature (Channel Specific) temperature is too high, the load will switch off to prevent damage.

8 Installation Guidelines If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. 8.1 Electrical Isolation A disconnect device must be provided in the installation and must be all-pole. It must be clearly labelled and positioned so that it is not obstructed by enclosures, wiring, or heavy equipment, ensuring easy access for maintenance and emergency disconnection. Ensure the power supply is isolated before starting any installation or maintenance; failure to do so may result in electrical shock or injury. 8.2 Mounting The DIN-8S module is designed for mounting on a DIN rail. Ensure the module is securely mounted within a compliant DIN enclosure using the appropriate fixings. 8.3 Enclosure and Environmental Protection Install the DIN-8S module in a suitably rated enclosure that protects against dust, moisture, and other contaminants according to its environment; failure to do so may lead to damage or malfunction. 8.4 Maximum and Minimum Loadings The load capacity of the DIN-8S module is load-type dependent; refer to the 'Load Types' section of the instruction manual to ensure the load is within the specified limits. Exceeding these limits may cause relay failure. 8.5 Overcurrent Protection Install appropriate overcurrent protection in line with the module, based on the electrical load and supply, to protect the module from potential short circuits or overloads. 8.6 Wiring All wiring should comply with the current local wiring regulations. This includes selecting the correct cable size, using appropriate termination methods, and ensuring mechanical protection for the wiring. 8.7 Ventilation and Cooling Ensure sufficient ventilation within the DIN enclosure to prevent overheating. Poor ventilation can lead to overheating and module failure. DIN-8S Instruction Manual | Page 10 Manual Version 1.0.2

8.8 Compatibility Verify that the DIN-8S module is compatible with other electrical components in the system. Incompatibility may result in malfunction, reduced performance, or damage to the module. Do not connect third-party devices to the Rako DIN bus. 8.9 Third-Party Accessories and Equipment The installer is responsible for providing the necessary cables, isolators, electrical loads, and ferrules compatible with the terminals on the DIN-8S unit. Refer to the manufacturer's instructions for all third-party devices. All cables must be appropriately rated for the intended load and comply with the relevant electrical standards. 8.10 Sound Pressure Levels The DIN-8S produces negligible sound pressure levels during normal operation (<70 dB(A) at 1 meter distance). The relays emit minor audible clicking sounds during switching operations. DIN-8S Instruction Manual | Page 11 Manual Version 1.0.2
