Electrical voltage
In the event of a fault, non-grounded metallic assemblies may be under voltage and then are
not touchable.
‣
When using metallic assemblies and installation equipment, observe the national
grounding provisions.
For immersion operation, install the individual modules away from the basin on a solid
base. Only carry out the final installation at the intended installation location. Select an
installation location that is easy to access.
For a complete installation of a measuring point, proceed as follows:
1. Install a retractable or a flow assembly (if used) into the process.
2. Connect the water supply to the rinse connections (if you use an assembly with cleaning
function).
3. Install and connect the oxygen sensor.
NOTICE
Installation error
Cable open circuit, loss of sensor due to cable separation, unscrewing of fluorescence cap
‣
Do not install the sensor suspended from the cable.
‣
Screw the sensor into the assembly so that the cable is not twisted.
‣
When installing or uninstalling the sensor body, hold it tightly. Turn using only the
hexagonal nut on the armored coupling. Otherwise you might unscrew the fluorescence
cap. This will then remain in the assembly or process.
‣
Avoid exerting excessive tensile force on the cable (e.g. from jerky pulling).
‣
Select an installation location that is easy to access for later calibrations.
‣
Observe the instructions for installing sensors in the Operating Instructions for the
assembly used.
