AC Power Service Requirements4-2 Express5800/320Fc: Site Planning GuideAC Power Service RequirementsTable 4-1 describes the nominal input line voltage (volts AC) and frequency (Hz)required for your system and optional components. The table also provides a referenceto a table that lists the receptacles to provide for each component.The power service must be properly wired and grounded according to local standardsand regulations. See Appendix B for electrical circuit and wiring information.N O T ECircuit breakers must provide a protective earth groundcurrent at a maximum of 3.5 milliamperes for each ACpower cord.Use the following worksheets to determine AC power requirements for the site.• In Table 4-2, determine the power requirements at the A-side power source.• In Table 4-3, determine the power requirements at the B-side power source.• In Table 4-4, determine the power requirements for components outside of thecabinet. These components can share a power source with the A-side or B-sidecomponents.To determine power requirementsProvide information in Tables 4-2, 4-3, and 4-4 as follows:1. In the Quantity column, write the number of each type of component.2. Multiply the entry in the Quantity column by the number in the @ Power (Watts)column, and enter the result in the AC Power (Extended) column.3. Add the values in the AC Power (Extended) column, and enter the sum on thebottom line. This value indicates the maximum power requirement for each powersource.Table 4-1.
