Routing cables; connecting and installing bus connectors 5.1.5 Cable shielding Definition Shielding is a means of weakening (attenuating) magnetic, electric and electromagnetic interference fields. Interference currents on cable shields are diverted to ground via the shield busbar, which forms a conductive connection with the housing. It is particularly important to ensure a low-ohmic connection to the protective conductor, as otherwise the interference currents themselves may become a source of interference.
Routing cables; connecting and installing bus connectors Correct shield Observe the following points: installation Use cable clamps made of metal to secure the braided shield. The enclosing clamps must hold a large part of the shield and make good contact (see Fig. 5-1). Connect the shield to a shield busbar immediately adjacent to the point where the cable enters the cabinet.
Routing cables; connecting and installing bus connectors 5.1.6 Measures to prevent interference voltages Overview Frequently, measures designed to suppress interference voltages are not adopted until the controller is in operation and reception of a traffic signal is found to be unsatisfactory. The outlay for post-installation measures (e.g. special contactors) can often be reduced to a significant extent if you observe the following points when configuring your control system.
