Procedure
Follow the steps below to connect a cable for an external antenna to the device:
1.
Insert the connector on the antenna cable into the R-SMA socket and tighten the sleeve
nut of the plug on the socket (key size SW8, tightening torque 1 Nm).
If you only use one antenna, you need to connect this to the device via antenna
connector R1 A1 (position A1).
NOTICE
The R-SMA socket may be damaged
When securing an antenna to the device, only the screw cap of the antenna can be
rotated. Rotating the entire antenna could damage the R-SMA connector on the
device.
2. Screw a terminating resistor to the unused antenna connector R1 A2 (position A2) if
you are only using one antenna.
NOTICE
UL approval only for use in buildings
Where NEC and CEC apply, the device and the antennas connected to it may only be
used in a closed building. For this reason, do not lead antennas into the outdoor area if
you need to meet UL requirements.
Note
Cabinet installation
When installing the device in a cabinet, you need to use detached antennas. A suitable
flexible connecting cable for the connection between the device and a detached antenna
are available from SIMATIC NET. You can find detailed information in section "Flexible
connecting cables, antennas and accessories (Page 25)".
