Power Requirements
Input Power Requirements
The main frame and drive expansion frames include dual AC power
modules. When using a redundant power configuration, connect each
input on the dual AC power module to a separate branch circuit, which
allows for failover in the event of a power failure in one of the circuits.
Dual AC and Dual AC with Convenience Outlets AC Input Phase
Requirement To prevent problems switching between two AC power
sources, the AC inputs for each module must be on the same phase. The
AC inputs for modules in different frames can be on different phases.
Dual AC and Dual AC with Convenience Outlets AC Input Voltage
Requirement The voltages of the two AC power sources must be the same
within a few volts. To ensure that this requirement is being met, measure
the voltages between the pins of the two input cables (IEC 60320-C19).
Note: As long as the voltage for each dual AC 2 power input is within
the range of 200-240 VAC, they do not need to be the same.
Caution
If the power sources for the dual AC inputs for a frame using the dual AC or dual AC
with convenience outlets are not on the same phase, damage to the library could
result. This restriction does not apply to the dual AC 2. See “Dual AC Power
Module” in the Spectra T950 Library User Guide for more information.
WARNING
Line voltage exists at these connectors.
Only qualified personnel should attempt to conduct this test.
Use extreme caution when taking measurements.
