AC line voltage requirements
The AC power requirements are essentially the same for both the primary
and the second racks except as indicated in Table 16 note 2. Each rack
operates on 200 VAC nominal, 20-amps, 50 or 60 Hz, single-phase power.
An independent branch circuit and circuit breaker is required for each AC
input power cord.
The following table lists specific power requirements.

1 60 Hz only.
2 Rated line current is the maximum allowable current under worst case conditions. This value applies to each individual
power cord and is specified in RMS amperes.
3 For the second rack, four power cords and circuit breakers are strongly recommended even though a minimum
configuration containing only one expansion disk chassis requires only 2 power cords and 2 circuit breakers. If a second
expansion disk chassis is added to the second rack, four power cords and four circuit breakers are required.
