Grounding
checks
This
product
must
only
be
connected
to
a
power
source
with
a
safety
electrical
ground
connection.
DANGER
If
more
than
one
product
is
installed
in
a
rack,
the
ground
connection
to
the
rack
is
even
more
important
because
the
rack
will
have
a
high
“ground
leakage
current”
(“touch
current”).
Prior
to
turning
on
power,
ensure
that
the
ground
connection
to
the
rack
has
been
checked
by
an
electrical
engineer
qualified
in
local
and
national
electrical
standards.
