Power - Grounding Information
ii
Like
many
modem
electrical devices,
your
ENSONIQ
product
has
a three-prong
power
cord
with
earth
ground
to ensure safe operation. Some
products
have
power
cords
with
only
two
prongs
and
no
earth
ground. To ensure safe operation,
modem
products
with
two-prong
power
cords
have
polarized plugs which
can
only be inserted into
an
outlet the
proper
way
.
Some products, such as older guitar amplifiers,
do
not
have
polarized
plugs
and
can
be
connected
to
an
outlet incorrectly. This
may
result
in
dangerous
high
voltages
on
the
audio
connections
that
could
cause
you
physical
harm
or damage any
properly
grounded
equipment
to
which
they are
connected, such as
your
ENSONIQ product.
To .avoid shock hazards or equipment damage,
we
recommend the
following
precautions:
• H
you
own
equipment
with
two
pronged
power
cords, check to see if
they
are
polarized
or
non-polarized. You might consider having
an
authorized
repair station change
any
non-
polarized
plugs
on
your
equipment to polarized
plugs
to avoid future
problems
.
Polarized
Non-polarized
• Exercise caution
when
using extension
cords
or
plug
adapters.
Proper
polarization
should
always
be
maintained from the outlet to the plug. The use of polarized extension cords
and
adapters
is the easiest
way
to maintain
proper
polarity.
•
Whenever
possible, connect all products
with
grounded
power
cords to
the
same
outlet
ground.
This will ensure a common
ground
level to prevent
equipment
damage
and
minimize
hum
in
the audio output. .
AC
outlet
testers are available from
many
electronic
supply
and
hardware
stores. These
can
be
used
to check for
proper
polarity of outlets
and
cords.
