Routing Cables Using Fiber Optics; Cable Routing; Bending Radius; Laying Fiber Optic Cables For Synchronized Coupling Of S7-400H - Siemens SIMATIC S7-400H Manual

Synchronization Module
During the storage of unused modules, you have to seal the fiber optic cable
interfaces with blind plugs to protect the optic (blind plugs are in the
synchronization module in the delivery state).

Routing Cables Using Fiber Optics

Cable Routing

Indoor fiber-optic cables (e.g., for connecting synchronization modules) are
permitted for use in buildings, cable ducts and channel trunking.
The maximum strain during installation is 1000 N and 150 N during operation.

Bending Radius

You may not go below the bending radius when laying the cable:
• Next to connector: 55 mm
• Otherwise: 30 mm

Laying Fiber Optic Cables for Synchronized Coupling of S7-400H

In addition, make sure the two fiber-optic cables are always laid isolated from each
other when routing the cable. Laying them separately enhances their availability
and protects then from potential dual faults in the event, say, of simultaneous
interruption of the fiber-optic cables.
Always make sure the fiber optic cables are connected to both CPUs before
switching on the power supply or the system, otherwise the CPUs may process the
user program as the master CPU.
