ctrlX HMI DE0015, DE0021 Multi-Touch
Displays (Housing Devices)
Connection
1. Connect the functional earth.
2. Connect the XCDI+tx interface at the control cabinet PC to the XCDi+rx in-
terface at the respective operating display using a CDI+ cable.
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 es-
tablished again. A direct connection of the functional earth between the opera-
tor display and the control cabinet PC is optimal. If the functional earth is con-
nected to a neutral point, the display has to be connected to this neutral point
as well.
When wiring Bosch Rexroth CDI cables with a diameter of 7.4 mm,
observe the following bending radii:
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 × ca-
●
ble 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
terface" on page 7
