Physical address for each actuator panel shall be written in front and in bold letters.
EIB Power Supply & Line Coupler Installation
Power Supply unit & Line Coupler shall be mounted in the same enclosures of actuators or in separate enclosures as per lighting control system manufactures design drawings.
The auxiliary voltage may not be used for other purpose than Bus.
Mains Supply shall be connected at Terminal L1, N.
Main shall be switched on, once the device has been correctly installed.
Universal Interface Installation
Interface shall be Installed in 3×3 back box.
EIB Bus cable shall be terminated at Bus terminal with correct polarity.
