Execution
Notes and explanations
1
Mount the CP on the DIN rail and connect it to
the module to its right.
Use a 35 mm DIN rail.
The slots to the left of the CPU are permitted.
2
Secure the DIN rail.
3
Secure the power supply wires to the power
output of the CPU.
4
Secure the wires of the power supply to the
plug supplied with the CP and insert the plug
in the socket on the top of the CP.
The pinning is shown beside the socket on the top of the hous-
ing. You will also find this in the section Pin assignment of the
socket for the external power supply (Page 136).
5
Connect the antenna to the SMA socket of the
CP.

Notice
•
Protect the antenna connector using suitable overvoltage protection equipment if the antenna cable is long-
er than 30 m.
•
Protect the antenna connector with suitable lightning protection if you install the antenna outdoors.
•
If you install several CPUs close to each other, keep to a minimum clearance of 50 cm between the anten-
nas.
6
Turn on the power supply.
7
Close the front covers of the module and keep
them closed during operation.
8
The remaining steps in commissioning involve
downloading the STEP 7 project data.
The STEP 7 project data of the CP is transferred when you
load to the station. To load the station, connect the engineer-
ing station on which the project data is located to the Ethernet
interface of the CPU.
You will find more detailed information on loading in the follow-
ing sections of the STEP 7 online help:
