Installation2.6 Required protective devices and cable cross-sectionsRecommended upstream protectionRecommended downstream protectionThe indicated protection ensuresdiscrimination for each output circuitdownstream of the UPS, whethersupplied by the Normal or the BypassAC source.If these recommendations are notfollowed, protection discriminationis not achieved and may result in apotential power interruption to theconnected devices.Required cable cross-sectionsTerminal-block cable capacity: 10 mm², solid or stranded wire (maximum 13 mm² or AWG 6).zCapacity for earthing conductor: 10 mm², solid or stranded wire (maximum 13 mm² or AWG 6).zNote: see the simplified diagrams in the appendix for common or separate AC inputs, indicating thepositions of the protection devices, the characteristics of the internal UPS fuses and UPS line currentsunder overload conditions.Note: see the simplified diagrams in the appendix for common or separate AC inputs, indicating thepositions of the protection devices, the characteristics of the internal UPS fuses and UPS line currentsunder overload conditions.UPSpowerratingCommon AC inputsUpstream circuit-breakerNormal / Bypass AC sourcesSeparate AC inputsUpstream circuit-breakerNormal AC sourceUpstream circuit-breakerBypass AC source5 kVA D curve - 40 A C curve - 32 A D curve - 40 A7 kVA D curve - 40 A C curve - 32 A D curve - 40 A11 kVA D curve - 63 A C curve - 40 A D curve - 63 AUPS powerratingDownstreamcircuit breaker5 kVA Z curve - 10 AC curve - 4 A7 kVA Z curve - 10 AC curve - 4 A11 kVA Z curve - 10 AC curve - 6 A
