9.6.3
9.6.3.1
The order of the terminals within an Inline station should depend on the current consumption
of the I/O from the potential jumpers U
As the voltage at every power terminal is reinjected into the potential jumpers U
the section (main circuit) between a bus coupler and a power terminal or between a power
terminal and another power terminal must always be considered when calculating the
current. If power terminals are not used, the entire station is a main circuit.
Within a main circuit, install the terminals according to their current consumption. Install
the terminals with the highest current consumption first. This has the advantage that the
high supply current does not flow through the entire main circuit and thus does not flow
through all the terminals.
The following order is recommended.
Please also observe the following notes:

In the event of any further restrictions regarding the position of a terminal, please refer
to the terminal-specific data sheet.
For the current consumption of the terminals, please refer to the relevant
terminal-specific data sheet.
