Mains Supply and Phases
SSL equipment is designed for connection to
– category TN – and is fitted with a protective fuse in the Live conductor only. It is not designed for use with Phase (Live) and Neutral connections reversed or where the Neutral conductor is not at earth potential (TT or IT supplies).
All mains powered assemblies must be connected to the same mains phase. In particular, note that as PSU | |||
redundancy is standard, the two input leads must NOT be connected across different phases. | |||
Mains cables will be coded with either of the following colour schemes: | |||

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.

If the console trim is removed for any reason then there may be sharp edges exposed on the frame metalwork.
