Operation
To operate an AS-i system a special AS-i power supply is required (e.g.
AC1216). The AS-i power supply supplies the yellow AS-i cable with
energy and implements a data decoupling to the voltage regulator of
the power supply. Standard power supplies would consider the AS-i
data signals as interference signals and suppress them.
Disconnect the power supply before connecting the AS-i DP
gateway.
The AS-i system is operated ungrounded. AS-i + and AS-i - are to
be symmetrical to the ground potential of the installation.
Ensure a low-resistance connection of the symmetry point of the
AS-i power supply (terminal "shield") to the ground of the instal-
lation.
