Handling instructions
NOTICE
Please keep to the following handling instructions to avoid damage:
Make sure that the selected cable is suitable for your particular application.
You should, for example, check the following:
Required temperature range
Resistance of the jacket materials to chemicals, water, oils, rodents etc. to which
your cable will be exposed when in use
Required mechanical properties (bending radii, tensile strain, transverse
compression)
Requirements regarding the behavior of the cable in fire
Suitability of the cable and connectors for the devices being connected
If in doubt, use a special cable to meet your requirements. You SIMATIC NET contact in
your Siemens branch will be happy to advise you.
Never exceed the maximum permitted forces (tensile strain, transverse compression
etc.) specified in the data sheet of the cable you are using. Excessive transverse
compression can, for example, arise when using screw-down clamps to secure the
cable.
Only use PCF fiber-optic cables in conjunction with devices approved for these cables.
Remember the maximum permitted cable lengths.
When cutting cable sections to length, make sure that no loops result and that the cable
is not twisted. Loops and torsion can cause kinks or tears under tensile loading and
cause damage to the cable.
Follow the steps described in these installation instructions and use only the tools
specified here.
Make sure that the outer jacket, the jackets of the cores, and the PCF optical fibers are
not damaged.
When stripping the core jacket, use only the opening labeled 1.0 mm on the stripping
pliers.
Dents or scratches can allow light to escape and increase the attenuation values and
cause link failure. Over time, these can also lead to breaks in fibers causing network
failure.
Never insert dirty connectors or connectors with protruding fibers into the device
sockets. This can destroy the optical transmit and receive elements.
When assembling adapters for connectors and when connecting the cable to them,
make sure that send and receive data are crossed in the cable.
Close unused connectors with dust protection caps. Remove the dust protection caps
only immediately before connecting cables together or plugging cables into devices.
