Connection with fibre optic cable
Devices of category 2 G/D for explosive areas have the connection solely by rail mounted screw terminals.

The fibre optic converter
inside the extended safety compartment is powered by the electronic unit. The
converter is pressure proof sealed, and the optical interface is intrinsically safe. Actuators can be fitted with
single line fibre optic interfaces (e.g. line or star structure), or with a redundant fibre optic interface for a ring
structure. The breakout has to be put inside the compartment. It is therefore important to keep the size of the
breakout small enough to be able to push it through a cable gland of the size M20. The standard connector is
of type F-SMA. The following pictures show the inside of the wiring compartment.

Setting of transmission power
The converter board has two switches S1 and S2. The switches can be used to set the transmission power
according to the requirements of the input and output independently. If the adjacent devices are only a short
distance apart, the appropriate switch should be switched to „-" (default setting). If the transmission power is
not sufficient to cover the distance between two devices, the switch can be set to position „+".
The two LEDs on the board show whether the power supply is OK (green LED), and whether data are
transferred via the optical PROFIBUS (yellow LED).
