Important Safety Information

The 12V PSU for Hub 2 is a power supply unit designed to connect Hub 2 control panels to 12V DC sources. This device must be installed by a qualified electrician only. Before starting the installation, ensure the device is disconnected from the mains. Always wait 5 minutes after disconnecting for the capacitors to discharge before disassembling the device. Never disassemble the device while it is under voltage.

Installation Process

1. Remove the screws and take off the device from the SmartBracket mounting panel by shifting it down with force.
2. Switch off the device by holding the power button for 2 seconds.
3. Disconnect the power and Ethernet cables.
4. Wait 5 minutes for the capacitors to discharge.
