2.3 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before working on the device, disconnect the power supply and cover up live
parts in the working environment.
Fitting and connecting device with data rail
If a data rail is used, bus line and power supply DC 30 V can be supplied to the device via data
rail contacts.
The connection of additional cables to the device via terminals is optional if the bus line and
power supply are already connected to the data rail via additional data rail connectors. In this
case, the terminals of the device can be used as additional data rail connectors to connect an
outgoing bus cable, for example.
If no data rail connectors are used, bus line and power supply DC 30 V must be connected to
the device via terminals. The data rail will then be supplied via the device.
Figure 2: Device connection with data rail
Data rail (6) is glued into mounting rail (5).
o
Snap device onto DIN rail.
o
Cover free areas of the data rail with cover strips (7).
Optional, if additional data rail connectors are available:
o
Connect power supply to the terminal (2) (Figure 1).
o
Connect bus line to terminal (1).
Fitting and connecting device without data rail
The device can be used without data rail. Bus line and power supply DC 30 V must be
connected to the device via terminals.
