Mains Supply and Phases

To ensure safe operation of this equipment, connect only to an ac. power source that contains a protective earthing (PE) conductor. This equipment is designed for connection to single phase supplies with the neutral conductor at earth potential – category TN or TT – and is fitted with a protective fuse in the live conductor only. This equipment is not designed for use with live and neutral connections reversed or where the neutral conductor is not at earth potential (IT supplies). This equipment should not be connected to a power system that switches open the return (neutral) lead when the return lead also functions as the protective earth (PE).

Mains Isolation and Over-Current Protection

An external disconnect device (switch) is required for this equipment which must be installed according to current wiring regulations. A detachable power cord, if fitted to this equipment, is a suitable disconnect device, otherwise an approved disconnect switch is required – the rating of which is defined in the product specification (Appendix A) and on the equipment itself.

Physical Safety

The console surface is too heavy for one person to move, ensure sufficient manpower is available when positioning the console. Take particular care when removing a fully populated RIO chassis from the equipment rack
