Eurorack Busboard

Please read this safety guide before installation or use.

Intended Use
• This product is a Eurorack power supply module (busboard/distribution board) intended to supply Eurorack-compatible synthesizer modules with ±12V and +5V.
• It must be installed in a suitable Eurorack case by the end customer.
• The power supply works with an external plug-in or desktop power adapter (not always included). Only use a compatible adapter with the specified voltage, current, and polarity.
• Any use outside the intended application may result in malfunction, fire hazard, or electric shock.

Installation and Use
• Disconnect the external power adapter from mains before installation or maintenance.
• Mount the power supply securely inside the case using suitable screws and spacers to avoid mechanical stress or short circuits.
• Ensure correct polarity and orientation when connecting modules. Incorrect connection may damage modules or the entire system.
• Do not exceed the maximum current ratings for each power rail.
• Ensure sufficient ventilation inside the case to prevent overheating.
• Route cables carefully to avoid kinks, pinching, or contact with sharp edges.
• Only use original or manufacturer-approved external power adapters.

Warnings
• Risk of electric shock: the product operates with voltages supplied from mains-powered adapters. Never touch live contacts.
• Risk of fire: overloading, blocked ventilation, or defective components can cause overheating.
• Risk of damage: incorrect polarity or overvoltage may permanently damage modules or the power supply.
• Short circuit hazard: prevent contacts or busboard rails from touching conductive objects.
• Small parts may pose a choking hazard. Keep away from children and pets.
• Do not open, modify, or repair the product yourself. Improper handling may cause injury or permanent damage.

Storage and Cleaning
• Store the product in a dry, cool place away from moisture and extreme temperatures.
• Disconnect the power adapter before cleaning.
• Clean with a dry cloth only. Do not use water or aggressive cleaning agents.

Responsibility
Users are solely responsible for proper assembly and testing. Contact manufacturer support for assistance if needed.

Environmental Safety
• Dispose of the module, its components, and packaging in accordance with local electronic waste regulations.

Liability Disclaimer
• The manufacturer is not responsible for any injury, damage, or malfunction resulting from improper installation, assembly, use, or modification of this product.
