Power Considerations
AC and DC power supplies, and an optional redundant (second) power supply, are available for most
systems. Be careful when connecting systems to the supply circuit so that wiring is not overloaded.
Note Refer to your hardware installation guide for ACand DC power specifications and for redundant power
supply availability.

AC Power

The system is designed for connection to TN powersystems. 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 plug-socket combination is accessible at all times, because it serves as the main
disconnecting device.

DC Power

Follow these guidelines for DC power supplies:
•ConnectDC-input power supplies only to a DC power source that complies with the safety extra-low
voltage (SELV) requirements in the UL 1950, CSA 950, EN 60950, and IEC 60950 standards.
•Ensure that there is a readily accessible disconnect device incorporated in the building'sinstallation
wiring.
•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 closed-loop or spade-type with upturned lugs, when
stranded wiring is required. These terminations should be the appropriate size for the wires and
should clamp both the insulation and the conductor.
•Ensure that no exposed portion of the DC-input powersource wire extends from the terminal block
plug. An exposed wire can conduct a harmful level of electricity.
