Electronic Earthing System is composed of one IIB aluminium alloy enclosure (EJB 8A type) inside which there is an electronic resistance/capacity device and externally a support hook, an earthing clamp, complete with 8 m of cable, to measure and check the continuity towards the earth, aiming to eliminate the electrostatic charges. Enclosure has on the cover a green and a red pilot light as agreement or refuse to proceed. Its modularity by jumpers or trimmers placed on the electronic card, allows the selection of different capacity or resistance sensibility levels.
