Installation Of Fiber-Optic Cables In The Enclosure - Siemens SIMATIC ET 200iSP Operating Instructions Manual

• Observe the specified bending radii when laying the cable.
• Do not use lubricants containing grease or oil.
You can use the lubricants listed below to facilitate pulling in the fiber-optic cables.
– Yellow ground (wire-pulling, lubricant from Klein Tools; 51000)
– Soft soap
– Dishwashing liquid
– Talcum powder
– Detergent
Pressure
Do not exert any pressure on the cable, for example, by the inappropriate use of clamps (cable
quick-mount) or cable ties. Furthermore, you must prevent anyone from stepping on the fiber-
optic cables.
Exposure to heat
The cables are sensitive to direct heat effects, i.e., the fiber-optic cable must not be worked on
with a hot air gun or gas burner, as is practiced, for example, with shrink-on sleeve technology.

Installation of fiber-optic cables in the enclosure

Permissible bending radii for assembled cables
When laying the cables (6XV1847-2C) assembled by SIEMENS, the bending radii must not fall
below the following values:
• When pulling in: 88 mm (multiple)
• After pulling in: 59 mm (once)
Use cable glands to avoid damage to the edges.
Note
When routing the cables, make sure that the two fiber-optic cables in a redundant system are
always routed separately. The separate routing increases the availability and protects against
possible double faults, e.g. in case of simultaneous interruption of the fiber-optic cables.
