Grounding Requirements
Due
to
electromagnetic
interference
(EMI)
filtering
in
each
dual
AC
power
supply,
the
leakage
current
for
main
frames
and
drive
frames
is
such
that
they
require
a
secure
connection
from
the
chassis
of
the
unit
to
an
earth
ground.
Use
one
or
more
of
the
following
methods
for
securing
a
ground
connection
when
installing
a
main
frame
or
drive
frame:
Note:
Cord
lock
brackets
and
cords
with
locking
connectors
are
not
compatible
and
cannot
be
used
simultaneously.
Add
cord
lock
brackets
(Spectra
Logic
part
number
5497)
to
all
drive
frames.
See
“Installing
Cord
Locks”
in
the
more
information.
Use
a
cord
with
locking
connectors
at
both
ends,
such
as
L6
20P
to
locking
C19
(Spectra
Logic
part
number
9594).
Use
a
dedicated
external
ground
wire
(Spectra
Logic
part
number
91017013)
from
the
chassis
screw
lug
to
the
building’s
earth
ground.
