2.2.6 Power Supply and AS-i Connection Method<br />
AS-i masters do not require a separate power supply. They are supplied in full from theASi<br />
cable (current consumption around 200 mA from AS-i). An additional 24 V powersupply is<br />
not required for the AS-i master. The AS-i master is simply connected to the AS-i cable. The<br />
master starts working when the power supply unit is switched on.<br />
Use a power supply unit that also supplies the AS-i master with voltage and, like all other<br />
AS-i <strong>com</strong>ponents, can be connected to the AS-i cable at any point, see also "Power Supply<br />
Units" on page 3-1.<br />
