ELECTRICAL CONNECTION
7.1. Cable connection with possibility of local HART communication
All connection and assembly activities must be performed with the power supply
disconnected and other external voltages, if used.
Incorrect connection of the probe may endanger safety.
Risk of electric shock and / or ignition in hazardous areas.
Make the electrical connection according to the diagram below. If the transmission line is led in the
open air, to distant rooms, it is recommended to assemble a junction box, e.g. PP type manufactured
by Aplisens S.A., to connect the probe cable with the further part of the transmission line. The junction
box should have IP65 protection grade and at the same time it should be unsealed enough to ensure
"breathing" of the probe's measuring element through the capillary tube which is a part of the cable.
Do not allow the outlet of the capillary to get dirty or water to get inside it.
In case of a long transmission line, it is recommended to lead the cable from the end of the probe cable
through a "twisted pair", and the input to the cooperating devices should also be equipped with an
overvoltage protection device, e.g. Aplisens UZ-2 system.
Figure 4. Electrical connection 4...20 mA of probes with HART communication.
The scheme for connecting the communicator or modem to the power supply and measurement
installation is shown in Figure 4.
The Aplisens HART/USB converter can also be supported by the Aplisens Mobile Configurator software
installed on an Android smartphone using wireless communication. The software is available on Google
