Make sure that the power supply connected to the NSA-series Industrial PC
satisfies the following specifications for NSA-series Industrial PC startup and
power interruption.
If the external 24 V DC input voltage is turned OFF, the NSA-series Industrial PC
operating system will start up when the rated input voltage is supplied to the NSA-
series Industrial PC. The input voltage must remain OFF for at least 10 s before it
is turned back ON. (OFF/ON interval: 10 s min.)
The NSA-series Industrial PC shuts down the operating system when it receives a
shutdown request from a software application, or when the user executes a
shutdown operation. When the shutdown is completed, the NSA-series Industrial
PC will turn OFF all DC outputs except the 5-Vs auxiliary power supply.
If the 24 V DC input voltage from the external power supply is interrupted, all
NSA-series Industrial PC power supplies, including the 5-Vs auxiliary power
supply, will turn OFF. If this occurs during any operation, including shutdown, that
operation may not be successfully completed. Be sure to turn OFF the external
24 V DC input voltage after the shut down is completed. The NSA-series Industrial
PC does not have UPS or other recovery functions for power outages or power
interruptions. These functions will have to be provided externally (on the system
side).
