Power
Phase
Imbalance
If
you
have
a
single-phase
power
control
compartment,
you
will
supply
single-phase
AC
power.
However,
if
you
have
a
two-phase
power
control
compartment,
you
will
have
to
supply
three-phase
power.
The
two-phase
power
control
compartment
only
uses
phases
1
and
2
and
the
neutral
of
incoming
three-phase
power.
This
may
result
in
a
power
imbalance
for
the
three-phase
power
system.
This
imbalance
of
power
increases
as
the
number
of
installed
racks
in
your
system
increases.
Note:
If
you
have a two-phase power control compartment,
you
should
consult
an
electrician to properly balance
the incoming three-phase power.
