The impedance must not exceed: - 50 mΩ through the joint. - 5 mΩ x metre of tray.(*) (*) Currently this valour is studied through document IEC/SC23A/WG12, CLC/TC213/WG-5 – 765. It will be changed to 50 mΩ x metre. The metre length and joining systems for the different sections that Schneider Electric has, as well as the joints of the different accessories supplied, comply with the electrical continuity test established in the afore- mentioned standard, guaranteeing the impedance established. To guarantee these impedance values tightening torque values of no less than 5 Nm are recommended, always using the joins recommended for each tray type, and taking sizes into account. To guarantee a safe installation, Schneider Electric recommends a proper earthing of all the elements that make up the system (sections and accessories), using the accessories designed specifically for this purpose. SCHNEIDER ELECTRIC RECOMMENDS NOT TO USE THE TRAYS AS EARTH OR NEUTRAL CONDUCTORS. SCHNEIDER ELECTRIC IS NOT RESPONSIBLE OF ANY DAMAGE IF YOU USE ACCESSORIES FROM OTHER MANUFACTURERS.
