Power Considerations
AC and DC power supplies, and an optional redundant (second) power supply, are available for most systems.
Note Refer to your hardware installation guide for AC and DC power specifications and for redundant power supply availability.
Be careful when connecting systems to the supply circuit so that wiring is not overloaded.
AC Power
•The system is designed for connection to TN power systems. A TN power system is a power distribution system with one point connected directly to earth (ground). The exposed conductive parts of the installation are connected to that point by protective earth conductors.
•Ensure that the
DC Power
•Connect
•Incorporate a readily accessible
•Ensure that power is removed from the DC circuit before installing or removing power supplies. Tape the switch handle of the DC circuit breaker in the off position.
•Use only copper conductors to connect to a DC terminal block.
•Use approved wiring terminations, such as
•Ensure that no exposed portion of the
Redundant Power
If your system includes an optional redundant (second) power supply, connect each of the two power supplies to different input power sources. Failure to do so makes the system susceptible to total power failure in the event that one of the power supplies fails.
