Bending radius for the fiber-optic cable
When placing the fiber-optic cable duplex core into the connector adapter and
when placing things on top of them, make sure that you do not go below the
permitted bending radius of 30 mm. Also read the installation guidelines for
fiber-optic cables in the ET 200S Distributed I/O System Manual or in the
SIMATIC NET - - PROFIBUS networks manual.
Using the fiber-optic cable again
Note
If you place used fiber-optic cable in the connector adapter, you must shorten both
cores of the fiber-optic cable by the bent lengths and remount the simplex
connectors.
In this manner you avoid possible attenuation losses from parts of the fiber-optic
cable duplex core that have been bent again and highly stressed.
Wiring the IM151-1 FO STANDARD interface module
To connect the supply voltage:
1. Strip the insulation from the wires for the supply voltage of the interface module.
2. Tighten the individual wires in the screw-type terminal.
Connecting the PROFIBUS DP:
1. Insert the fiber-optic cable with the mounted connector adapters in the IM151-1
FO STANDARD.
2. Push up the handle of the connector adapter that is sticking out.
Make sure they are in the correct position: the sender fiber-optic cable is plugged
into the receiver socket and the receiver fiber-optic cable into the sender socket of
the fiber-optic interface of the IM151-1 FO STANDARD.
If the IM151-1 FO STANDARD is the last node of the fiber-optic cable network, you
must close the unoccupied fiber-optic cable interface with filler plugs (which are in
place when the IM151-1 FO STANDARD is delivered).
