• For 125/230VAC rated equipment, a appropriately rated AC circuit breaker must be
installed.
• 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™ RX1501. 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
Alarm Relay Connector
user interface.
A common application for this output is to signal an alarm in case of a power failure.
