Installation in a panel

What to do / steps
1. Bore holes for DIN M4 screws on the panel. Follow the instructions in section Dimensions
2. Screw the CP 243-1 to the panel to the right of the CPU for horizontal installation and
3. Insert the ribbon cable of the CP 243-1 in the connector under the front cover of the
4. Connect the grounding terminal:
5. Connect the power supply.
6. Connect the Ethernet cable.
Installation is now complete.
Note
Keep the front cover of the CP 243-1 closed during operation.
During installation, make sure that the upper and lower ventilation slits of the module are not
obstructed and good ventilation is possible.

adjacent module or the S7-200 CPU. The shape of the plug prevents it from being
incorrectly inserted.
Connect the grounding terminal of the CP 243-1 with the nearest available ground to
obtain the highest possible interference immunity. We recommend that you connect all
grounding terminals individually. Use wires with a cross section of 1.5 mm
The transmission medium is a 2 x 2-wire, twisted pair, shielded cable with a characteristic
impedance of 100 ohms. The transmission properties of this cable must meet category 5
requirements (Cat5 cable). The maximum length of the connection between an end
device and network component (link segment) is limited to 100 m with the components
defined in IEEE802.3.
The RJ-45 connector on the CP 243-1 is shielded so that, in combination with a shielded
Ethernet cable, a continuous cable shield is created that ensures interference-free
Ethernet transmission. The shield of the RJ-45 connector is connected via the grounding
terminal of the CP 243-1.
We recommend that you shield and ground the Ethernet connection as described in the
document "SIMATIC NET Twisted Pair and Fiber-Optic Networks".
