Combined fibre-optic connection (plastic and glass)
If the relay is provided with the optional fibre-optic communication module for
plastic and glass fibre, the plastic fibre-optic cables are connected to terminals X5.3-
RX (Receiver) and X5.3-TX (Transmitter) and the glass fibre-optic cables to
terminals X5.4-RX (Receiver) and X5.4-TX (Transmitter).
The fibre-optic interface is selected with jumpers X6 and X2 located on the PCB of
the communication module (see Fig. 5.2.3.-2).
