The device requires an external 24 V ±10 % DC power supply (unregulated) as system power supply. The supply voltage is to be connected via the appropriate terminals on ibaW750 device and it is protected against reverse polarity.

Tip
	If required, you can reorder 24V DIN rail or plug-in power supply units. Please contact the iba support.

The 24 V voltage is internally converted to a 5 V operating voltage (galvanically connected). The voltage does not only supply the device, but is also available via the terminal bus for supplying the corresponding connected terminals.

Up to 1700 mA can be used to supply the terminals. If a higher load is necessary, additional system power supply modules are required (e. g. Wago 750-613).

Some terminals do not need a supply voltage from the system supply, but use the additional field supply.

Caution!
	The length of the supply cable between the power source and the device must not be longer than 30 m.
