Hybrid Cables
The hybrid cables should be installed such that they are protected from mechanical wear
such as sharp edges or moving parts. During installation always keep the protective tube in
such a position that the single mode fiber connector is protected from dust. The operating
temperature for the cables is -40 to +80°C (-40 to 176 °F) and the installation temperature is
-20 to +80°C (-4 to 176 °F). The bending radius of the cables may never be smaller than
100 mm (4 ").
Note
Throughout the entire installation, keep the fiber ends protected by the protective tubes;
observe that these should only be removed by authorized personnel.
There are three kinds of cables used for the LDS 6 depending on the application:
● Hybrid cables for all types of systems except oxygen. These are installed between the
LDS 6 and the transmitter sensor.
● Hybrid cables for oxygen systems only, also installed between the LDS 6 and the
transmitter sensor.
● Loop cables, same for all systems, are installed between the transmitter sensor and the
receiver sensor.

Power Supply Connections
WARNING
The respective country-specific standards for the installation of power systems with rated
voltages below 1000 V must be followed. Failure to observe these regulations may result in
death, personal injury and/or damage to property.
General
● Check that the local voltage agrees with that specified on the label on the analyzer.
● The cable must be tested according to IEC 60227 or IEC 60245 and must be suitable for
70 °C (158 °F).
● The power cable must be routed separately from the hybrid cables.
