3.3.1 Connecting PROFINET
Cables
O
n modules 55287, 55288, 55289 and 55339 only bus cables with M12 D-coded connectors
can be used. The bus connection for modules 55264, 55268, 55269, and 55283 is a RJ-45 in
push-pull design.
The bus connection for the module 55264 is a M23 hybrid plug.
For correct selection of cables, please refer to document "PROFINET Cabling and Interconnec-
tion Technology“. In addition, please comply with the corresponding installation guidelines of the
"PNO Association" (Profibus user organization).
Connecting to MVK-MPNIO
Connect functional earth (GND) to the FE connection on the housing
Connect incoming PROFINET cables to a bus connection
Connect a possible additional PROFINET cable to the other bus connection
 or close off the open bus connection with a blind plug.
3.3.2 Connecting the Power Supply
Reverse polarity of the power supply can damage the module. Therefore, we
recommend using preterminated connectors from Murrelektronik.
Connecting Supply Voltage to the Module
The supply of actuators and sensors requires auxiliary power. The electronics of the MVK-
MPNIO are supplied via the sensor power supply.
The sensor power supply voltage must not be deactivatable. It supplies the
power for the electronics.
