7.2 Connect the supply voltage
7.2.1 Standard configuration: 24 V power supply and AS-i power supply/
supplies
► Connect the supply voltage inputs of the device to the power supply intended
for this purpose.
AS-i bus 1
Connect the pins AS-i 1 + and AS-i 1 - of terminal X1 to the AS-i power supply
(e.g. AC1254) of the first AS-i bus.
AS-i bus 2
Connect the pins AS-i 2 + and AS-i 2 - of terminal X1 to the AS-i power supply
(e.g. AC1254) of the second AS-i bus.
Power must be applied simultaneously to the Safe-IO module (terminal X4)
and to the device (terminal X2).
24 V device supply
Connect the pins 24 V and 0 V of terminal X2 to a 24 V DC power supply
(18...32 V SELV/PELV).
24 V Safe-IO power supply
Connect the pins 24 V and GND of terminal X4 to a 24 V DC power supply
(18...32 V SELV/PELV).
Recommendation: Link the voltage supply through from terminal X4 directly
to terminal X2.
► Ensure a low-resistance connection of the symmetry point of the device
(terminal X1, pin 5 FE) to the ground of the installation.
► For the 24 V power supply (device, Safe-IO), select a power supply which
supplies an output current of at least 3 A.
► The cable length of the DC supply between power supply and AC422S is to be
limited to max. 3 m.
