Figure 3-3 Connecting up an FO cable
For the FO cable, use the second opening from the left in the seal. Cable routing is
illustrated in the figure above. For individual cores immediately following the connector, the
minimum bending radius is 25 mm. Refer to the specification of the cable you are using for
the minimum permitted bending radius of the cable within the jacket. Make sure that the FO
cable is not sharply kinked after passing through the housing.
An adhesive sealing foil must be used in the housing sealing with FO cables (position A in
the figure above). For more detailed information, refer to the section "Connecting the
cables".
WARNING
To operate the SCALANCE W786 safely, the chassis ground connector must have a
suitable cable connected. Do not use the SCALANCE W786 without a ground cable
connected.
The chassis ground connector is located on the rear of the device (M4 thread). Connect the
ground cable before you mount the SCALANCE W786 on a wall or on the optional mounting
plate. Once the SCALANCE W786 is mounted, the connector is no longer accessible.
