(a) Input voltage
Input voltage is a voltage at which the power supply part operates normally. If it is outside the specified range,
the Ethernet adapter module may detect an error and stop its operation.
(b) Inrush current
Inrush current is a large current that instantaneously flows into a circuit immediately after power is applied.
Reapplying input power after power-off may cause an inrush current that exceeds the specified value. Allow 5
seconds or more before reapplying input power.
Also, select appropriate fuses or breakers for external circuits, considering the possibility of meltdown, sensing
property, and other items shown in this section.
(c) Allowable momentary power failure time
If a momentary power failure occurs, the system detects an input voltage failure and stops its operation.
Allowable momentary power failure time is the period of time that the system can continue its operation after
power is restored.
If a momentary stop exceeding the allowable momentary power failure time occurs, the operation will be
continued by the load of the power supply part, or will be initially started. When the operation is continued, the
operational behavior is the same as that for the momentary stop within the allowable momentary power failure
time.
