DC Power Source Warnings
Warning Risk of electrical shock. Because a system is fully powered on after all power connections are
made, it can cause shock if a power cable is disconnected from the chassis. To reduce the risk,
a readily accessible disconnect device, such as a fuse in a fuse panel, must be provided in the
fixed wiring for each DC power source. It must be suitable for the rated voltage and current
specified.
Warning Risk of electrical shock. Safe operation of this equipment requires connection to a ground point.
To prevent possible injury from voltages on the telecommunications network, disconnect all
telecommunications network lines before disconnecting the unit from the ground point.
