Planning for power
Each enclosure is provided power through two power supplies. Either power supply unit can power the enclosure independently if there is a loss of input power to the other power supply in the enclosure. The system requires 240V high line power.
Plan to connect the power cords of the power supplies on the left side of the
enclosures (when viewed from the rear) to one power source, and the power cords of the power
supplies on the right side of the enclosures to another power source. For more information on power
requirements, refer to Environmental requirements.
Attention: The
power cord is the main power disconnect. Ensure that the socket outlets are located near the
equipment and are easily accessible.
The power supply units in a control enclosure are not interchangeable with the power supply units in an expansion enclosure.
