Installing and connecting up
NOTICE
Ensuring ventilation
During installation, make sure that the upper and lower ventilation slits of the module are
not obstructed and good ventilation is possible.
1. Install the CP on the S7 standard rail.
Slots 4 to 11 are permitted for the CP in racks 0 to 3 (connected by IM 360/361). Follow
the steps described in detail in /12/ (Page 62) in the sections dealing with installation and
wirin
g.
Note
No installation in an expansion rack
The CP cannot be operated in an expansion rack that is connected via the IM 365.
Reason: The required communication bus is not connected to the expansion rack via the
IM 365.
2. Establish the connection via the enclosed bus connector to the backplane bus.
3. Connect the CP to the power supply.
Follow the steps as described in detail in /12/ (Page 62) when wiring between the power
s
upply and the CPU.
NOTICE
Same power supply
The CPU, CP and IM (if one exists) must be connected to the same power supply.
Only wire up the S7300 / C7300 with the power switched off!
4. Connect the CP to Industrial Ethernet.
An Ethernet cable can also be inserted and removed with the power supply on.
The remaining steps in commissioning involve downloading the configuration data.
