Input voltages and frequencies
This information lists the voltages or frequencies that are accepted by the IBM XIV
Storage System.
Table 22 provides the voltages and frequencies that are accepted by the XIV
system. For more information, see “Leakage current” on page xiii.
Table 22. Input voltages and frequencies
Characteristics Voltage or frequency
Nominal input voltages 200, 220, or 240 V ac
Maximum input current 30 A or 60 A
Minimum input voltage 180 V ac
Maximum input voltage 264 V ac
Maximum ground-leakage current 0.3 A
Steady-state input frequencies 50±3 Hz or 60±3 Hz
Power line disturbance (PLD) input
frequencies
50±3 Hz or 60±3 Hz
Main-power cables specifications
Plan for power cable, connector, and receptacle requirements.
The XIV systems are available in multiple main-power cable configurations. The
automatic transfer switch (ATS) is chosen based on the required main-power
cables.
Attention: The regional designations are general. The ATS assigned to the
regional designation might not be accurate for your country. If the input voltage
for the country uses a wye circuit, use the appropriate ATS and main-power cables
for EMEA (Europe, Middle East, and Africa) and Asia/Pacific. If input voltage for
the country uses a delta circuit, use the appropriate ATS and main-power cables
for United States, Canada, Latin America. For more information about electric
currents for various countries, see the International Trade Administration website
(http://www.trade.gov/mas/ian/ecw/all.html).
