Cable joint
Fig. 4 Cable joint
Connections of the sensor cable inside the cable joint are explained in
figure 3. If shielded cable is used cable shields and possible excess
wires need to be connected to the same point in galvanic contact.
Please make sure, that the sensor and cable between OMS-1 control
unit and the sensor do not exceed the maximum allowed electrical
parameters
– see chapter 7 Technical data.
IP rating of the cable joint is IP68. Make sure, that the cable joint is
closed properly.
Notice in cabling: Risk of electrostatic charging!
If the sensor cable must be extended and there is a need for
equipotential grounding, it should be done with the junction box LJB2.
The cabling between the OMS-1 control unit and the junction box
should be done with a shielded twisted pair instrument cable. Maximum
cable length is 100 m.
