Connecting Power - Panasonic NS1000 Manual

Connecting the AC Cord
Using the AC Cord supplied with the unit, connect it to the PBX and secure with the supplied AC Cord Clip.
UPS System:
A UPS should be connected to the PBX to provide temporary in the event of a power failure.
When using the recommended UPS (APC RS Series with USB interface), the PBX can shutdown automatically by sending a warning signal to
the PBX through the USB port.
By shutting down correctly, data loss or serious damage to the PBX caused by a sudden power cut can be prevented.
When power is restored, turn off the PBX using the power switch first, and then turn the PBX back on before starting the PBX.
