Fasten the bus cable to the BusAdapter for the PROFINET IO connection. Note the pin assign‐
ment on the BusAdapter/plug. You can find information about this in the documentation "
SIMAT‐
IC; Distributed I/O; BusAdapters for Distributed I/O
".
Recommendation:
When installing the CFU in a housing, use cables that are suitable for a FastConnect Ethernet
connection.
You can fasten them at any time to a PROFINET BusAdapter with a FastConnect Ethernet
connection (e.g. BusAdapter BA 2×FC).
7
Insert and screw the selected BusAdapter on the CFU (terminal X5).
8
CFU PA only:
When you use the CFU PA, ensure that the shielded lines of the fieldbus cables are connected
correctly. You can find information on this in section "CFU PA in aluminum housing: Connecting
the field bus (Page 141)".
If available and necessary, you can fasten the cables to the shielding bus using cable ties.
9
Only SIMATIC CFU ... with aluminum housing:
When you use the CFU in the housing, the cable glands ensure sealing between the cables and
the housing. Ensure that the required reducing inserts and blanking plugs are installed in the
cable glands to seal the housing.
Tighten the cap nuts of the cable glands.
Ensure that the pressure compensation element is correctly installed in the housing.
Note:
Ensure there is strain relief for the cables outside the housing. Even when installed in the hous‐
ing, the cable glands do not serve as strain relief.
10 Fasten the grounding cable to the mounting rail or housing.
11 Connect the cables of the power supply (PS1 to X80 / PS2 to X81). Observe the pin assignment
on the plug connector (see section "Connecting the CFU to the PROFINET IO (Page 66)").
12 Only SIMATIC CFU ... with aluminum housing:
When you use the CFU in the housing, check the housing (housing lid).
● Make sure the housing and all seals are not damaged and correctly installed.
● Ensure that there are no foreign bodies between the housing parts (e.g. between the housing
cover and the housing base).
● Close the housing.
