Warning
This product relies on the building’s installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.
(240 VAC, 10A international) is used on the phase conductors (all current-carrying
conductors). To see translations of the warnings that appear in the publication, refer to
the
Regulatory Compliance and Safety Information
document that accompanied this
device.
Caution
In a DC power supply installation, do not connect the 48 VDC Return to chassis ground at
the Cisco AS5400. A single-point ground is recommended at the power distribution rack.
