Page 6: Introduction
EN.IO.SGE.25.MODBUS INTRODUCTION 1.1. Purpose of the document The subject of manual are smart level probes: SGE-25.Modbus and SGE-25S.Modbus hereinafter referred to as probes in the manual. The manual applies to the following versions: standard and intrin- sically safe Exi. The manual contains data, guidelines and general recommendations for the safe installation and oper- ation of the probes, as well as procedures in the event of a possible failure. -

Probe identification Depending on the version of the probe, the nameplates may differ in the amount of information and parameters. Table 1. Symbols appearing on the probe’s nameplate. -
Page 9: Installation
6.1. General recommendation The probe can be hung on the power cable, e.g. by using from the Aplisens SG cable hanger (item 1 in fig. 1). In the event of frequent removal of the probe or when there is a risk of catching on protruding elements during pulling up, it is recommended to hang the probe on a steel cord using the carrying eye (item 2 in Fig. -
Page 10: Electrical Connection
The electrical connection should be made according to Table. 2. It is recommended to install the PP-Modbus connection box manufactured by Aplisens S.A. to connect the probe cable with the rest of the transmission line. The PP-Modbus junction box is non-hermetic (pressure inside is equal to atmospheric pressure) due to the use of an air filter, which is required for the probe to operate correctly. -

Page 13: Overvoltage Protection
EN.IO.SGE.25.MODBUS 7.4. Overvoltage protection Probes can be exposed to switching surges, or other surges, such as those resulting from lightning. Protection against surges between the wires of the transmission line is provided by surge diodes. For protection against surges between the transmission line and earth or housing (which are not protected by diodes connected between the line conductors), the probes are equipped with additional protection in the form of surge arrestors. -
