AC Power Service Requirements
Table 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 reference
to a table that lists the receptacles to provide for each component.

cabinet. These components can share a power source with the A-side or B-side
components.
To determine power requirements
Provide information in Tables 4-2, 4-3, and
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 the
bottom line. This value indicates the maximum power requirement for each power
source.

Circuit breakers must provide a protective earth ground
current at a maximum of 3.5 milliamperes for each AC
power cord.
