11.2.3 Connection of the Power Supply Voltage
NOTICE
It is
not permissible
to feed through the power supply voltage through the CBX station
and to supply it to another CBX station via 24V connector! A feed through
of the +24 V power supply voltage can cause damage on the CBX modules.

11.2.4 Connection of CAN
Figure. 55:
Connecting the CAN signals to the CAN-CBX station
Generally the CAN signals can be fed via the CAN connector of the first CAN-CBX module of the
CBX station. The signals are then connected through the CAN-CBX station via the InRailBus. To
lead through the CAN signals the CAN bus connector of the last CAN-CBX module of the CAN-
CBX station has to be used. The CAN connectors of the CAN-CBX modules which are not at the
ends of the CAN-CBX station must not be connected to the CAN bus, because this would cause
incorrect branching.
A bus termination must be connected to the CAN connector of the CAN-CBX module at the end of
the CBX-InRailBus (see Fig. 55), if the CAN bus ends there.
