4.2.1

Power supply X2

The wires for the auxilliary voltage are screwed on terminal X2 at he bottom side of
the device. The assignment of the terminals is printed at the front side or can be read
in this manual. Because the device has no ON/OFF switch this switch must be
installed external if it´s necessary.

Fibre Optic (FO) connections R and T


Only optical fibres prepared according the regulations are to be used. The
admissible optical budget is to be observed

FO-types (only multimode) and max. distance see technical datas.

Transmitter diodes are printed with T1 to T5.

Receiver diodes are printed with R1 to R5.

The FO-cables must be crossed, that means a FO-connection is done between
Transmitter and Receiver and vice versa.

Pluging the D-Sub connector


After having plugged the D-Sub connector, make sure it is screwed tightly.
