Note:
The countries or regions indicated
here are for general guidance only.
Local electrical codes governing
wire size, wire type (AWG or met-
ric) and plug type should be con-
sulted to determine which of these
available line cords/plugs is correct
in your country to make proper
connection to your AC mains.
Please consult a qualified, licensed
electrician for more information.
Products with 3-phase inputs
Some of the higher power products
exceed the capability of a single
phase line. Agilent offers several
power products which require
3-phase inputs, including the
5kW668XAand6.6kW669XA
DC source family. For 3-phase
power distribution up to the
building, there are two different
distribution systems in wide use:
delta, predominantly used in the
US; and wye predominantly used
in Europe. However, for service
inside the building, the 5 wire wye
is the predominant configuration.
Products which are delta loads,
are compatible with either delta
or wye. Agilent 3-phase products
are delta loads.
In selecting the correct operating
voltage for 3-phase products you
need to distinguish between the
line-to-line and the line-to-neutral
voltages. The line-to-line voltage
is the square root of 3 x the line-
to-neutral voltage. It is the line-to-
line voltage that is used to specify
the input voltage to be applied to
Agilent power products.
