The COM interface may only be wired as a RS-232 or as a RS-
422/485 connection !
Simultaneous wiring of the RS-232 and RS-422/485 interface is not
allowed !
* Do
NOT
connect the optional external keyboard to live equipment !
** Please note that the Ethernet connection is either for an optical
fibre connection (X10) or for a copper connection (X11),
depending on the version ordered !
The optical fiber connection requires a multimode optical fiber
cable with 62.5 µm core diameter and 125 µm external diameter.
Copper wires with cross sections of between 0.2 mm² (AWG24)
and 2.5 mm² (AWG14) may be connected to any of the terminals
of the HMI devices.
Which cable cross sections are chosen should be decided on the
basis of relevant regulations, such as DIN VDE 0298. Factors that
might require a larger cross section, such as current, increased
temperatures, cable bundling, etc. must also be taken into
account !
