5 VDC Distribution for H41X
The 5 V power supply is distributed to the extension rack through terminal blocks XG6 for 5 V
and XG7 for GND. The extension rack must be connected to 2 parallel wires (2.5 mm²) for 5 V
and GND in a star configuration so that the 5 V power supply is applied to the I/O processing
modules at sufficiently high voltage. HIMA uses yellow wires for 5 V and green wires for GND.
The wire length within the control cabinet is limited to 3 m. If the H41X system is distributed
among two control cabinets, the 5 V power supply must be provided in the control cabinet
without base rack by a separate power supply unit, see Chapter 4.3.8 for details.
The wires on the extension rack are connected to the flat connectors XG.4 (5 V) and XG.12
(GND). The voltage is distributed to the I/O modules via the backplane PCB.
5 VDC connector XG6.1.2 (base rack), XG.4 (extension rack).
GND connector XG7.1.2 (base rack), XG.12 (extension rack).

When designing the 5 V voltage supply, the current consumption of all I/O modules and the
modules in the base rack must be taken into account. For details on the power consumption of
the individual modules, refer to the module-specific manuals.
