•The placement of the AC and DC power supplies is not slot-dependent. Either PM slot can be used for AC or DC power.

•For 110/230VAC rated equipment, an appropriately rated AC circuit breaker must be installed.

•For 125/250VDC rated equipment, a appropriately rated DC circuit breaker must be installed.

•For maximum redundancy in a dual power supply configuration, it is recommended to use two independent power sources.

•It is recommended to provide a separate circuit breaker for each power supply module.

•Equipment must be installed according to applicable local wiring codes.

3.3.Critical Alarm Wiring

The Critical Alarm output relay signals critical error conditions that may occur on the RuggedBackbone™ RX1510. The contacts are energized upon power-up of the unit and remain energized unless a critical alarm condition is detected. Relay connections are shown in the Critical Alarm Relay Connector diagram. You can configure control of the relay output through the ROX™ user interface.

A common application for this output is to signal an alarm in case of a power failure.
