Appendix InRailBus (Option)
9.2.3 Connection of the Power Supply Voltage
The power supply voltage can be connected via the +24V connector for the power supply voltage
or via InRailBus connector.
Attention:
Please note the safety instructions to requirements on the supply current circuit (see
page 4).
Figure. 16:
Connecting the power supply voltage to the CAN-CBX station
Earthing the mounting rail
Note:
Connect the mounting rail to functional earth potential. Please note that the impedance
of the connecting cable has to be kept low.
Functional earth is a current path of low impedance between current circuits and earth, which is
used to increase the interference immunity. It is not intended as protective measure and does not
protect against accidental contact.
