Wiring operations shall only be carried out without voltage!
Taking into account the potential occurrence of electrostatic discharge on non-conducting
parts of the level meter, it is necessary to ground the flange of level meters ULM–53Xi–20–F
and sensors ULS–53Xi–20–F, located in an explosive atmosphere, using a ground terminal!
The supply source should be preferably designed as a stabilized source of safe voltage 18 V
to 36 V DC (max. 30 V DC for version Xi), which is part of the downstream processing or display system.
In case of strong ambient electromagnetic disturbance, parallel run of the input cable with the power line
or its length exceeding 30 m, we recommend using a shielded cable.

The positive supply pole +U is connected to the
brown wire of the connected cable, the negative
pole is connected to the blue wire of the con-
nected cable. Load is connected to the black
wire of the cable.
It is also necessary to design and take measures to reduce the effects of static electricity
to a safe level in the wiring.
Installation in explosive atmospheres needs to be carried out in compliance with EN 60079-14
(Electrical installations for explosive gaseous atmospheres – Part 14: Electrical installations
in dangerous areas other than mining) and possibly also in compliance with other standards
relating to the area concerned.
