Important points to remember about I/O wiring: • Always use copper wire. • Use wire with an insulation rating of 600V or greater. • Separate control and signal wires from power wires by at least 0.3 meters (1.0 ft). • For CE compliance, 115V digital input wiring must be shielded or must not exceed 30 m (98.4 ft) in length. • Follow these guides to maintain electrical safety for all user-accessible low voltage circuits for I/O terminals that are designated for 24V or lower voltage. Standards are safety extra low voltage (SELV) and protective extra low voltage (PELV). SELV is as defined in IEC 61010-2-201 and PELV is as defined in IEC 61131-2. – Do not connect to a circuit of higher voltage. – Do not connect to a circuit that is not adequately insulated from dangerous voltages with double or reinforced insulation within other connected equipment or wiring. • Provide a common earth reference for all equipment that is connected to the drive. This common earth reference is to provide electrical safety for user-accessible low voltage I/O circuits that are referenced to earth (PELV circuits) and that can be touched simultaneously. • If the wires are short and contained within a cabinet that has no sensitive circuits, the use of shielded wire is not necessary, but is always recommended.
