TNT 35/7-24V
3 Fast commissioning / operating principle
Notice!
Below you will find a short description for the initial commissioning of the PROFINET
gateway MA 248i. Detailed explanations for the listed points can be found throughout the
handbook.
3.1 Mounting
The gateway mounting plate MA 248i can be mounted in two different ways:
•using four threaded holes (M6) or
• using two M8x6 screws on the two lateral grooves.
3.2 Device arrangement and selection of the mounting location
Ideally, the MA 248i should be mounted so that it is easily accessible near the Ident device
in order to ensure good operability, e.g., for configuring the connected device.
Detailed information can be found in chapter 6.3.1.
3.3 Electrical connection
The devices from the MA 2xxi family feature four M12 connectors/sockets which are coded
differently depending on the interface.
The voltage supply (PWR IN) as well as the switching inputs/outputs (PWR OUT or PWR IN)
are connected there. The number and function of the switching inputs/outputs is dependent
on the connected end device.
An internal RS 232 interface is used for connecting the respective Leuze device. Another
internal RS 232 interface functions as a service interface for configuring the connected
device via a serial null modem cable.
