AC Power Sources and Requirements
This
Terminal
is
intended to be operated from
a
sing
le
phase,
earth,
referenced power source
having
one current carrying conductor (neutral) at ground
(earth)
potential.
Operation from power sources
where both
curre nt-carrying conductors are
live
with respect to earth (such
as
phase-to-plyase
on a
multiphase
system,
or across the
legs
of
a
117-234
single
phase three-wire system)
is
not recommend
-
ed
because
on
ly
the line conductor has overcurrent
(fuse) protection within the
instrument.

This Terminal
is
designed
tooperate
from either a 110

line voltage
source that 'has
a
frequency of 48
to 440
Hz.
In
addition
,
any
of three
voltage
ranges
for 100
Vac or four voltage
ranges for
220 Vac
may
be
selected. Voltage
