Wiring and set-up of the slaves
In general, the AS-i devices are short-circuit proof and reverse-polarity protected. Control cabinet
modules, however, should be wired while disconnected.
7.3.1
Connecting slaves
► Switch off the controllere and its supply.
NOTICE
Malfunction of the machine/plant in which the unit is installed!
Damage or destruction of the devices by a short circuit when working while live.
► The device must be installed and connected by a qualified electrician.
► Disconnect power before connecting the device to avoid short circuits during installation.
► Only install the controllere and the slaves while disconnected!
AS-i field modules can be installed without risk while live.
SmartLine modules:
► Connect (control cabinet) modules.
► Remove the Combicon connector with AS-i connection to enable automatic addressing of the
slaves in rising order.
AS-i field modules:
AS-i field modules usually consist of a lower part for the connection of the yellow (and black) flat cable
and an upper part with the electronics.
► Insert the cable in the lower parts, but do not yet screw/clamp the upper parts on the lower parts to
enable automatic addressing of the slaves in rising order.
7.3.2
