InstallationPlanning the Installation1-4 D000140-000SFigure 1-2 Fiber Optic Bend RadiusUninterruptible Power SupplyConsider the following when selecting Uninterruptible Power Supply (UPS)equipment:• The minimum amperage requirements for a UPS:• Calculate VA (Volt-Amps): Locate the voltage and amperage requirementsfor each piece of equipment (usually located on a sticker on the back or bottomof the equipment). Multiply the numbers together to get VA.• Add the VA from each piece of equipment together to find the total VArequirement. Then add 30% to determine the minimum amperagerequirements for the UPS.• Transition time (the time necessary for the UPS to transfer from utility power tofull-load battery power).• The longest potential time period the UPS might be required to supply backuppower.• Whether or not the UPS unit also provides online protection.Table 1-2.
