5.2.1
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.
Connection to screw terminals:
Terminal cross section:
max. 2,5 mm
2
Stripping length:
3 bis 5 mm
Cable cross section:
0,14 bis 1,5 mm
2
(Single core cable or litz wire)
5.2.2
Alarm relay terminals X7
X5 offers a potential free contact, which is closed if the device fails.
The loss of the power supply is a device failure.
The wires for the alarm contacts are screwed on terminal X7 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.
Connection to screw terminals:
Terminal cross section:
max. 2,5 mm
2
Stripping length:
3 bis 5 mm
Cable cross section:
0,14 bis 1,5 mm

(Single core cable or litz wire)
5.2.3
Fibre Optic (FO) connections Rx, Tx
•
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 Tx.
•
Receiver diodes are printed with Rx.
•
The FO-cables must be crossed, that means a FO-connection is
done between Tx output and Rx input and vice versa.
Note
When installing optical fibres the prescripted
bending radius is to be observed.
