Operating range: –40.0 to –72.0 VDC
NOTE: If the input voltage from the DC power source drops between
–37.5 and –39.5 VDC, the router automatically shuts down. During
automatic shutdown, the circuit remains active. When the input
voltage returns to –43 to –44 VDC, the router automatically starts
up again and the system returns to normal operation within 30
minutes. No operator intervention is required.
