must install the equipment in accordance with any regional or national electrical wiring codes, such as
the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7.
Furthermore, you must verify that all power distribution devices used in the installation, such as branch
wiring and receptacles, are listed or certified grounding-type devices. Because of the high
ground-leakage currents associated with multiple systems connected to the same power source, Cisco
recommends the use of a PDU that is either permanently wired to the building’s branch circuit or
includes a nondetachable cord that is wired to an industrial-style plug. NEMA locking-style plugs or
those complying with IEC 60309 are considered suitable for this purpose. Using common power outlet
strips for the controller is not recommended.
