NOTE
• 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.
Section 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.
