Interra KNX Power Supply 640 mA Aux. Voltage 30V DC

ITN DIAGRAM MOUNTING, COMMISSIONING AND SAFETY NOTES

• The device may only be installed and put into operation by a qualified electrician or authorized personnel.
• Mounting Location: Installation only on a 35 mm DIN rail of a distribution board.
• Device needs at least 4 standard modules width at installation.
• Screw down strength is less than 0.4Nm.
• Avoid contact with rain, liquids and corrosive gases.
• Check Connections: Re-tighten all connections after installation.
• Cable Connections: Do not get wrong connection for KNX Black and Red wires, device input AC wires and external supply output wires.
• Power supply has an additional

R900-0164/0132/0116 KNX Power Supplies generate the KNX system voltage (SELV). For this purpose, 3 different models have been developed considering the needs. Main differences between models are power consumptions and rated currents. The bus line is decoupled from the power supply by an integrated choke. The two color LED indicates device output status.

CONNECTIO

30 VDC short circuit and overload protected voltage output that can be used to power an additional bus line (in combination with a separate choke).
• The voltage output is overload, short circuit and over temperature protected.
• Output without choke can be used as a constant 30 VDC supply and output with choke can be used as a KNX Bus supply.
