3.6.3.1 Connection
The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply.
The power supply is provided via the fieldbus coupler/controller and, if necessary,
in addition via internal system supply modules “System Power Supply 24 VDC
XTR (750-613/040-000)”. The power supply is reverse voltage protected.
Do not use an incorrect voltage/frequency!
The use of an incorrect supply voltage or frequency can cause severe damage to
the components.

The fed-in 24 VDC supplies all internal system components, e.g. fieldbus
coupler/controller electronics, fieldbus interface and I/O modules via the local bus
(5 VDC system voltage). The 5 VDC system voltage is galvanically connected to
the 24 VDC supply voltage.
