EXTERNAL PSU INPUT

Therearescrewconnectorsprovidedforadditional12V&24VDCpowersuppliesifthenetworkcurrentrequirement
exceedsthatofthesystemSMPSU.ThepowerratingandstandbybatterycapacityofadditionalPSU’smustbecalculated
accordingly.Considerationshouldalsobegiventothepowerconductorsonthesitewiringnetworktoensuretheyare
capableofcarryingtheincreasedcurrentwithminimumvoltagedrop.FusesF1‐F6willneedtobeup‐ratedinlinewiththe
increasedcurrentcapacity.
