Mounting and Wiring
General description
The N-system DIN-rail device (2 SUs) can be installed to
N-system distribution boards, surface or flush mounted,
or to any DIN-rail EN 50022-35 x 7,5 available that has a
data rail installed.
The connection to the bus line is established by clicking
the device onto the DIN-rail (with a data rail installed).
Take care that the type plates of all devices on a DIN-rail
can be read in the same direction, guaranteeing the
devices are polarised correctly.
