Perform
the
following:
a.
Disconnect
the
mainline
ac
power
cable
from
the
customer’s
ac
power
outlet.
b.
Use
a
multimeter
to
measure
the
ac
voltage
at
the
customer’s
ac
power
outlet.
Note:
Some
system
models
have
more
than
one
mainline
ac
power
cable.
For
these
models,
disconnect
all
the
mainline
ac
power
cables
and
measure
the
ac
voltage
at
all
ac
power
outlets
before
answering
the
following
question.

to
240
V
ac
?
v
Yes
:
Continue
with
the
next
step.
v
No
:
Perform
the
following:
a.
Inform
the
customer
that
the

voltage
at
the
power
outlet
is
not
correct.
b.
Reconnect
the
mainline
ac
power
cables
to
the
power
outlet
when
the
ac
voltage
at
the
power
outlet
is
correct.
This
ends
the
procedure.
