Lead breakage as well as a short circuit caused by the power rail is prevented due
to the power rail's solid construction.
Device Terminal Connections
In addition to or in combination with power rail connections, the KF… designs can
be conventionally connected by means of removable device terminals. The termi-
nal arrangement is shown below.
The device terminals consist of screw type cable piercing terminals which allow for
the connection of 14 AWG cables (2.5 mm²). The connectors are 3 pin connectors;
they can be keyed to prevent connection errors.
Removable terminals simplify the assembly of the switch encloser and allow for
the replacement of components without taking the system off line.
Gateway Power Supply
The gateway is supplied through the AS-i circuit. A connection to the AS-i cable is
established by means of the power rail and/or with the device terminals.The ma-
ster is powered by the AS-i network. An AS-i connection is established by means
of the power rail or the device terminals. The terminal layout is displayed in the dia-
gram below.
It is important to note when using the power unit that these AS-Interfaces are com-
patible and have the necessary decoupling coils.
4.4.4 The PROFIBUS Interface
The serial interface is a 9 pin SUB-D connector. It is located on the right side of the
device front. The other possibility is to use the device terminals. The wiring is
shown in the picture before.
The AS-i/PROFIBUS gateway with an RS 485 interface transmitts and receives
through pins 3 and 8 of the SUB-D connector or terminals 25 and 26 of the device
