The standard covers all UPS systems intended for installation in any operator-accessible area. It specifies safety requirements for the operator and anyone else encountering the equipment, and where specially stated, for service personnel. The objective is to ensure the safety of installed equipment – either single unit or as a system of interconnected units – subject to installing, operating and maintaining the equipment as prescribed by the manufacturer. EN 62040-Part 1 is to be used in conjunction with EN60950:2006 ‘Safety of information technology equipment including electrical business equipment’. The standard also incorporates, by dated or undated reference, provisions from other publications – as do Parts 2 and 3 as described below.
