Connecting 24 V DC supply voltage
The power for the CMK2000 is supplied via an external 24 V
DC SELV power supply.
Connecting to functional ground (FE)
Connect the functional ground (e.g. from the DIN rail) in
order to discharge EMI such as bursts or surges to the FE
terminal.
Conductor cross-section: 0.5 ... 6.0 mm
Note
EMC-compliant functional ground
Use as short a stranded-wire conductor as possible with
•
a large cross section.
Compliance with the technical specifications of the
•
device can only be assured if a correct functional
grounding is adhered to.
Connecting LOGO! with CMK2000 via Ethernet
The connection between the LOGO! 8 and the CMK2000 is
via Ethernet. Use a shielded Ethernet cable (CAT5e) with a
shielded connector.
NOTICE
Do not violate the minimum bending radius limit of the
Ethernet cable, otherwise this will result in attenuation of
the shielding effect. Furthermore there is a danger that the
cable shield will break.
Note
We recommend using the RJ45 connector from the
Siemens FastConnect system.
