Fibre-optic Cables
WARNING!
Laser rays!
Do not look directly into the fiber-optic elements!
Signals transmitted via optical fibers are unaffected by interference. The fibers guarantee electrical isolation
between the connections. Transmit and receive connections are represented by symbols.
The character idle state for the optical fibre interface is „Light off". If the character idle state is to be changed,
use the operating program DIGSI, as described in the SIPROTEC 4 System Description.
Further Connections
For further connections a visual inspection is sufficient for the time being. Electrical and functional controls are
performed during commissioning (see the following main section).
