Fast commissioning / operating principle

Notice!
Below you will find a short description for the initial commissioning of the PROFIBUS
gateway MA 204i. Detailed explanations for the listed points can be found throughout the
handbook.
3.1

Mounting

The gateway mounting plate MA
• using four threaded holes (M 6) or
• using two M8x6 screws on the two lateral grooves.
3.2

Device arrangement and selection of the mounting location

Ideally, the MA
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
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.
