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 coupler/controller
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.
coupler/controller electronics, field bus interface and bus modules via the
internal bus (5 V system voltage). The 5
V system voltage is electrically
connected to the 24 V system supply.
