Page 10: Installation
EN.IO.PCE.PRE.28.MODBUS INSTALLATION 6.1. General recommendations It is recommended that in case of a gaseous medium, the transmitters should be installed above the measuring point so that condensate may flow to the point from which the meas- ured pressure is collected, while in case of liquid medium or steam, it should be installed below the point of pressure intake. -

EN.IO.PCE.PRE.28.MODBUS Figure 1. Diagram of connecting the transmitters in the MODBUS network. 7.3. Equipotential bonding In the case of using a cable in the screen, connect the screen on one side at the transmitter’s power supply point. The transmitter in intrinsically version should be powered from a galvanically separated power source or, if this is not possible, equipotential bonding of the transmitter and the power supply device should be ensured by means of equipotential bonding conductors. -

(which are not protected by diodes connected between the line wires), additional protection is applied in the form of gas surge arresters. Additionally, an external protective device can be used, e.g. the UZ-2 system by APLISENS or others. 7.5. Final inspection of cabling After completing the electrical installation of the transmitter it is necessary to check the following: −... -

The PCE/PRE-28.Modbus16 transmitter with PZ, PZ2 type electrical connection has a 560Ω resistor, which can be used as a line/bus terminator. Switching on the resistor can be done using the DIP 1- position switch by switching to the ON position.
- Page 23 EN.IO.PCE.PRE.28.MODBUS EN.IX.PCE.PRE.28.MODBUS 5. Special conditions for safe use 1. The transmitters do not meet the insulation test (500 V rms) required by EN 60079 11:2012. This must be taken into account during installation of the device. ➔Table Z1 2. For the ambient temperature range, see as well as the information on the transmit- ters rating plate.
