North American AC power cabling The HP SVS200 rack requires 20-amp, single-phase 200 VAC power supplied by four power cords with plugs, four receptacles, and four main disconnect devices (circuit breakers). The HP SVS200 comes from the HP factory with the AC power cords and plugs you have ordered. Plug types rated for 30 Amps and 20 Amps are specified under the heading, AC inputs earlier in this chapter. The opposite end of the power cord connects to the HP SVS200 power distribution unit input, which is a type IEC320 C20 connector. Connect each AC power cable to a separate receptacle on a separate circuit breaker, and connect each pair of power cords (the left pair and the right pair) to separate distribution panels to ensure power fault tolerance. CAUTION: Do not apply power until instructed to do so by HP. An HP representative should be present whenever the system is being connected to a new power source. North American branch circuit requirements To protect the system, your building must be wired correctly. Each supply ("hot") conductor must be protected by a short-circuit protective device and by an overcurrent protective device. The table listed under AC line voltage requirements provides specifications for the overcurrent protective devices required for single-phase operation. All protective devices must comply with national standards of the country where the unit is to be installed. If a protective device interrupts any supply conductor, it must also interrupt all other supply conductors. 40 Electrical specifications

North American AC power cabling
The HP SVS200 rack requires
20-amp, single-phase 200 VAC power
supplied by four power cords with
plugs, four receptacles, and four main disconnect devices (circuit breakers).
The HP SVS200 comes from the HP factory with the AC power cords and plugs you have ordered.
Plug types rated for 30 Amps and 20 Amps are speci
fi
ed under the heading,
AC inputs
earlier in
this chapter. The opposite end of the power cord connects to the HP SVS200 power distribution unit
input, which is a type IEC320 C20 connector.
Connect each AC power cable to a separate receptacle on a separate circuit breaker, and connect
each pair of power cords (the left pair and the right pair) to separate distribution panels to ensure
power fault tolerance.
CAUTION:
Do not apply power until instructed to do so by HP. An HP representative should be present whenever the
system is being connected to a new power source.
North American branch circuit requirements
To protect the system, your building must be wired correctly. Each supply (“hot”) conductor must be
protected by a short-circuit protective device and by an overcurrent protective device. The table listed
under
AC line voltage requirements
provides speci
fi
cations for the overcurrent protective devices required
for single-phase operation.
All protective devices must comply with national standards of the country where the unit is to be installed.
If a protective device interrupts any supply conductor, it must also interrupt all other supply conductors.
