Please observe the following installation instructions:
1.) Install in accordance with the manufacturer's specifications and the valid standards and regulations.
- Do not operate the level sensor outside of the electrical, thermal and mechanical parameters
2.) The intrinsically-safe input power circuit of the Levelflex M is isolated from ground potential and has a dielectric strength of at
least 500 Vrms with respect to it.
2.1 For grounding the screen, see figure 3 and figure 4.
3.) The relationship between the permitted ambient temperature for the electronics housing, dependent on the range of
application, and the temperature classes is shown in the tables (Tab. 1 and Tab. 3).
4.) After aligning (rotating) the housing, retighten the fixing screw (see Operating Instructions).
5.) Use connecting cable for continuous duty temperature ≥ Ta + 5 K
6a.) Install the device to exclude any mechanical damage or friction during the application. Pay particular attention to flow condi-
tions and fittings.
6b.) Special conditions (X marking)
The probes (rod and rope version) of the level radar Levelflex M type FMP 41C-....... have plastic surfaces, which can become
electrostatically charged.
For areas requiring instruments of category II 1 G or II 2 G, the electrostatic limits have to be observed.

Measures:
Instruments with flange cladding (plastic) may be installed in areas requiring instruments of category II 1 G or II 2 G without
further protective measures, if charging of the flange cladding is prevented by the installation (e.g. no exposed plastic
surfaces or installation in metallic connection parts/nozzles).
