2.7.2.1 Connection
The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply
(-15% or +20 %). The power supply is provided via the ECO coupler and, if
necessary, in addition via the internal system supply modules (750-613). The
voltage supply is reverse voltage protected.
Attention
The use of an incorrect supply voltage or frequency can cause severe damage
to the component.

The direct current supplies all internal system components, e.g. ECO coupler
electronics, fieldbus interface and bus modules via the internal bus (5 V sys-
tem voltage). The 5 V system voltage is electrically connected to the 24 V sys-
tem supply.
