Electrical connection The connection supply must be made in the type of connection intrinsic safety Ex ia IIC and connected
only to certified intrinsically safe circuits with safe electrical isolation. For this purpose one of our
approved Ex - isolating switching relays Type ER-14x, KR-163, XR-4, XR-6 is to be used. (see section
10). The container and the medium must be grounded.
Float Switch withe cable connection All electrical connections must be made

Technical data See datasheet of the desired device 05-06-01
Handling / Repair / Maintenance The filling level sensors are measuring instruments and accordingly handled with care! Before using the
float switch it must be ensured that the materials of the float switch remain sufficiently resistant
against the liquids to be monitored and all external influences, both chemically and mechanically. To
avoid compromising functions, the environment of the float switch action range must be free from
interferences (e.g. magnetic field, mechanical obstacles, ...). Generally, major forces such as impacts,
knocks, bending or similar should be avoided. The connecting cable must not be damaged since the IP
protection class is otherwise not maintained. Appropriate maintenance / cleaning intervals must be
provided.
