5.2.3 Voltage supply

• The Communication Unit is supplied with voltage via the AS-i bus cable.

• Access to parameters of a device that is disconnected from the mains is not possible.

• Permissible voltage (DC) / max. current:

• U = 29.5 ... 31.6 V (according to AS-i specification)

•I

max

= 400 mA

Low-voltage supply via the AS-i-bus cable

In case of low-voltage supply via the AS-i bus cable, communication with the slaves is still possible

if no mains voltage is available.

• A previous mains connection (400 V) is not required.

• The digital inputs DI1 ... DI5, RFR and the analog input can still be evaluated.

• The AS-i input ports DI0 ... DI3 represent the digital inputs DI1 ... DI4 (see AS-i concept of the

Communication Unit ( 33)). The current status of these inputs can be called.

• All digital input and output data which can be selected by the inverter are deleted or invalid..

• External sensors are also supplied via the AS-i bus cable.
