Connection notes
•
Install the device on a 35 mm DIN rail according to
DIN EN 60715.
•
To avoid contact resistance, only use clean, corrosion-
free DIN rails.
•
End brackets can be mounted on both sides of the de-
vice to stop the devices from slipping on the DIN rail
(see Page 3 for ordering details).
10.1
Combined assembly (modular star coupler)
•
Connect together the required number of DIN rail con-
nectors for the connection station. Two DIN rail connec-
tors are required for each device (see A in Figure 8).
•
Push the connected DIN rail connectors onto the DIN
rail (B and C).
•
Place the device onto the DIN rail from above. The up-
per holding keyway of the device must be hooked onto
the top edge of the DIN rail (see Figure 9). Make sure
that it is aligned correctly with the DIN rail connectors.
•
Once the device has been snapped on properly, check
that it is fixed securely on the DIN rail.

Combined assembly
CAUTION: Electrical voltage
The device is only intended for operation with
SELV according to IEC 60950/EN 60950/
VDE 0805.
NOTE: Malfunction
Connect the DIN rail with the protective earth via
a grounding terminal block. The devices are
grounded when they are snapped onto the DIN
rail (installation according to PELV).
This ensures that the shielding is effective. Con-
nect protective earth ground with low impedance.
NOTE: Device damage
Only mount and remove devices when the power
supply is disconnected.
NOTE: Device damage
The maximum current load in a star coupler must
not be exceed 2 A.
Therefore, a star coupler must not consist of more
than ten (10) devices.
