Voltage
The voltage in the segment circuit is DC 24 V.
Current carrying capacity
The maximum current carrying capacity is 8 A (total current with the main cir‐
cuit). If the limit value for a voltage jumper U
M
is reached (total current of U
S
and U
M
), a new power terminal must be used.
Generation of U
S
The segment voltage U
S
can be provided in various ways:
1.
The segment voltage can be fed at the IndraControl L45/L65/L85 or at a
power terminal.
2.
The segment voltage can be tapped from the main voltage, either at the
IndraControl L45/L65/L85 or at a power terminal using a jumper or a
switch.
3.
A segment terminal with fuse can be used. In this terminal, the segment
voltage is automatically tapped from the main voltage.
At the 120 V and 230 V voltage levels, it is not possible to set up
segments. In this case, only the main circuit is used. Special power
terminals are to be used.

Segment circuit
The voltages U
M
and U
S
are electrically isolated from U
L
.
Requirement: Power supply units that are electrically isolated from
the power supply unit for U
L
are used for voltages U
M
and U
S
.
When designing the station, please note that the total current in the
segment circuit U
S
and the main circuit UM must not exceed 8 A.
U
M
is interrupted by the PWR IN terminal.
U
S
is interrupted by the PWR/IN and SEG/F terminals.
+24 V Uninterruptible Power Supply UPS (Currently not Supported)
Connect the uninterrruptible power supply UPS to contact 2.1. The UPS is only
internally required in the control.
Function
The supply buffers the logic voltage for a short period and thus allows to save
high data volume. Thus, a power down delay can be achieved when switching
off U
LS
. It is possible to backup higher data volume on the CF.
