DANGER
Never install power cables when the power is on.
Before installing power cables, ensure that the device is adequately grounded.
NOTICE
With the 110 V AC power supply, the USG9520 must use 110 V dual-live-wire AC input to
meet the maximum system power consumption requirements with the full configuration. This
is because AC power modules are half-load output with 110 V AC input, which cannot meet
system power consumption requirements.
l
There is a length of copper core inside the cable. Do not connect anything to the core.
