B.1 Overview
The CVCF provides a stable power supply to the system even in the event of a power abnormality or major power
outage.
Through a connection between the CVCF and a UPC port on the main unit with a signal cable, the CVCF can notify
the main unit of abnormal power conditions when it detects them. On receiving such notification, the main unit
performs emergency shutdown processing, and thus can safely stop operation.
The following figure shows the locations of the UPC ports of the PRIMEQUEST 1000 series:
