    EMC requirements is not possible without the use of proper cables and connector/gland assemblies. Bronkhorst® recommends the use of their standard cables. These cables have the right connectors and if loose ends are used, these will be marked to prevent wrong connection. When using other cables, cable wire diameters should be sufficient to carry the supply current and voltage losses must be kept as low as possible.
