2.2.7 Installing Power Cables - AC Power Distribution
When the USG9580 uses AC power supply, two external AC power chassis are added to the
DC power supply system to form an AC power supply system. Four AC power cables are
used to connect each AC power chassis to the AC PDF.
Context
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 USG9580 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. This does not meet
the system power consumption requirements.
l
There is a length of copper core inside the cable. Do not connect anything to the core.
