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.
• Always use the pulling loop to pull in the PCF standard cable. Never pull the cable by
the connector or exposed cores.
• 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.
• Ensure that the outer jacket and the core jackets of the cable are not damaged.
• Never insert dirty connectors or connectors with protruding fibers into the device
sockets. This can destroy the optical transmit and receive elements.
• When connecting the cable, make sure that the send and received data are crossed
over in the cable.
