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. 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.
Risk of electrical shock. Disconnect all telecommunications network lines
before disconnecting the unit from the ground point. Safe operation of this
equipment requires connection to a ground point.
