Note
Long synchronization cables may increase cycle times. This extension can have the factor 2 -
5 with a cable length of 10 km.
5.5 Removing the synchronization module
1. Press lightly on the release of the fiber-optic cable and remove it from the synchronization
module.
2. Fold the clip of the synchronization module to the front and remove the synchronization
module from the H-CPU interface.
3. Place the dummy plug on the synchronization module.
4. Repeat this procedure for all interfaces and both H-CPUs.
5.6 Installation of fiber-optic cables
Introduction
Fiber-optic cables may only be installed by trained and qualified personnel. Comply with the
applicable regulations. The installation must be carried out with meticulous care, because
faulty installations represent the most common source of error. Causes are:
● Kinking of the fiber-optic cable due to an insufficient bending radius.
● Crushing of the cable as a result of excess forces caused by persons treading on the cable,
or by pinching, or by the load of other heavy cables.
● Overstretching due to high tensile forces.
● Damage on sharp edges etc.
Permitted bending radius for prefabricated cables
The following bending radii must not be undershot when installation the cable (6ES7960–
1AA04–5xA0) prefabricated by SIEMENS.
● During installation: 90 mm (multiple times)
● After installation: 60 mm (once)
Permitted bending radii for prefabricated cables
When you install self-assembled cable make sure to comply with the bending radii specified by
the manufacturer. Note that approx. 50 mm of space is available for the connector and the fiber-
optic cable under the front over of the CPU and that no tight bending radius of a fiber-optic cable
is therefore possible in the proximity of the connector.
