Electrical Requirements
Site Wiring and Power Requirements
Each enclosure has two power and cooling modules for redundancy. If full
redundancy is required, use a separate power source for each module. The AC
power supply unit in each power and cooling module is auto-ranging and is
automatically configured to an input voltage range from 88–264 VAC with an input
frequency of 47–63 Hz. The power and cooling modules meet standard voltage
requirements for both U.S. and international operation. The power and cooling
modules use standard industrial wiring with line-to-neutral or line-to-line power
connections.
Power Cord Requirements
Each enclosure is shipped with two AC power cords that are appropriate for use in
a typical outlet in the destination country. Each power cord connects one of the
power and cooling modules to an independent, external power source. To ensure
power redundancy, connect the two power cords to two separate circuits; for
example, to one commercial circuit and one uninterruptible power source (UPS).
