1
Connect the bus wire to the B screw terminals.
Loop to other control elements of the Niko Home Control installation if required.
2
Connect the potential-free push button or NPN transistor output.
Technical data
• resting potential: 26 Vdc (SELV, safety extra-low voltage)
• dimensions: 40 x 27 x 5 mm (HxWxD)
• CE marking
• ambient temperature: -25 - 55°C
• Only connect the push-button interface to an SELV (safety extra-low voltage) contact and NOT to the 230 V
mains voltage.
• Ensure that there is no contact between loose wires and other wires.
• The cable length between the push-button interface and the push button or transistor output should not
exceed 2 m.
• The push-button interface can be used in an outdoor environment provided that the unit is fitted with
splash-proof housing (e.g. New Hydro).
