NOTICE
Ensure that the functional earth is connected, as otherwise the electronics can
be destroyed by a potential difference between the operating display and the
control cabinet PC if the voltage supply is interrupted to only one device and
established again. A direct connection of the functional earth between the
operator display and the control cabinet PC is optimal. If the functional earth is
connected to a neutral point, the control cabinet PC has to be connected to this
neutral point as well.
When installing CDI cables with a diameter of 7.4 mm, observe the
following bending radius:
Radius (when bended once while routing): 4 × cable diameter
●
Minimum bending radius (when moved permanently): 8 × cable
●
diameter
Optimum bending radius (when moved permanently): 12.5 ×
●
cable diameter
Operation breakdown due to mechanical forces on the CDI cables.
Avoid mechanical stress (tensile, compressive, torsional and lateral
forces) caused by plugs to the RJ45 socket.
Malfunctions caused by using inappropriate cables.
Use only cables listed in

10.10.2 Connecting the control cabinet PC to multiple operating dis-
plays
Up to three operating displays IndraControl DR/DE can be connected serially to
the IndraControl PR4 devices using the CDI+ interface. The operating displays
only operate in the "Clone" mode. The advanced mode can only be used if a
second display is connected to the display port. The touch function is always
active on all operating displays. Entries can not be blocked at individual
operating displays.
