Note
•
If the external input voltage is interrupted, it must remain OFF for at least 10 s
before it is turned back ON. (OFF/ON interval: 10 s min.)
•
If the external input voltage is interrupted during any operation, including
shutdown, that operation may not be successfully completed. Shut down the
NSA-series Industrial PC and turn OFF the external 24 V DC input voltage.
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).
•
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 outages.
•
The entire system may shut down depending on how the power is turned ON
or OFF. Follow the correct procedure for turning the power ON and OFF.
