Installation

Connection diagrams

• 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).
To connect the push-button interface:
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.
