+24 V Supply of Main Circuit UM
The 24 V voltage for supplying the main circuit UM that is to be fed in at
terminals 2.1 and 2.2 is not used in the IndraControl L40.
The main circuit U
M starts at the IndraControl L40 or at a power terminal
and is supplied through all following modules up to the next power
terminal. At the next power terminal, a new circuit is started; its potential
is isolated from the previous one.
Several power terminals can be used within one station.
Several independent segments can be created within the main circuit.
The main circuit provides the voltage potential, from which the segment
voltages (U
S
) are derived. The splitting into segments permits to protect or
switch e. g. the supply of several actuators separately.
The maximum current carrying capacity is 8 A. If the limit has been
reached, a new power terminal must be used.

In the simplest case, the main voltage U
M
can be supplied at the
IndraControl L40.
The main voltage U
M
can also be supplied via a power terminal. A power
terminal must be used in the following cases:
1 An electrical isolation is to be set up.
2 The maximum current carrying capacity of a voltage jumper (U
