(1) For the power supply modules that can operate in an extended temperature range, the usable powers are subject to derating (written in bold) in the temperature range of 60...70 °C (140...158 °F). (2) There is no derating for the redundant power supply modules.
24V_SENSORS Output
The 24V_SENSORS output is the 24 Vdc sensor power supply output and is only available on the following modules:
Excessive load on the 24V_SENSORS output causes limitation of the available current. Reduce the current consumption on the 24V_SENSORS output.
WARNING
UNEXPECTED EQUIPMENT OPERATION
Do not exceed the 24V_SENSORS output power rating.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Power Limits
Excessive load can cause the power supply to trip.
WARNING
UNEXPECTED EQUIPMENT OPERATION
Do not exceed the total useful power rating of the module.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Follow these rules to establish the power used by power supply modules:
Once a power supply has tripped, disconnect the power supply from its power source for 5 minutes in order to restore its internal circuit breaker.
NOTICE
RECOVERY TIME AFTER TRIPPING
After tripping, remove the power to the power supply module and wait 5 minutes before applying the power again.
Failure to follow these instructions can result in equipment damage.
The redundant power supplies are not summable. The global power of the rack cannot exceed the capacity of a single supply.
