If desired and codes permit cabling may be used for these signals but for maximum noise immunity the cabling must contain overall foil and braided shields and be terminated as described in the preceding paragraph Cable is recommended for all of the analog and digital remote control signals including the relay controlled DC I O high voltage output signal fault output signal Again for maximum noise immunity the cabling must contain overall foil and braided shields and be terminated in a continuous 360 manner as described in the preceding paragraph Special fittings have been provided on the control panel for termina tion of these cables at that point The use of these fittings is described in the corresponding sections of this manual Using the methods previously described the 9060 Controller have been successfully tested to the stringent standards of the Electromagnet ic Compatibility Directive of the European Union The results conclude that these units are neither a source of electrical noise nor 9060 Cascade Low Voltage Controller Installation 14 9060 Cascade Low Voltage Controller Installation affected by electrical noise when the above methods are utilized CONNECTIONS For maximum noise immunity I O wiring should be run in conduit or cables having a foil shield with an overall braided shield The foil shield provides 100 shielding while the braid provides a means of making proper 360 shield
