The 7.5 V Inline voltage U
L
the external +24 V voltage U
The internal voltages required in the IndraControl L10 are generated from the
24 V supply voltage U (terminal 1.2).
LS
U is electrically isolated from the voltages U
LS
Requirement: A power supply unit that is electrically isolated from
the power supply units for U
U and U are not electrically isolated from each other.
M S
The 24 V voltage for supplying the main circuit U
2.1 and 2.2 is not used in the IndraControl L10.
The main circuit U starts at the IndraControl L10 or at a power terminal and is
M
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.
