~CAUTION
About Power supply wires
If
the
length
of
the
power
and
ground
cables
exceed 1 m,
or
if
you
connect
more
than
one
amplifier, a
distribution
block
should be used.

* Connect all equipment
to
the
same ground
point
while
keeping wire length
as
short
as
possible.
Ensure
that
you install a correctly-rated in-line fuse

Cautions on wire lead connections
When using
third-party
wire
cables (power supply
wire), use
the
supplied screws
to
simplify
the
connection. Refer
to
the
description
below
for
the
proper
procedure.
If
you are in
doubt
about
how
to
make this connection, consult
your
dealer.

If
the
wire gauge used
is
unknown,
ask
your
dealer.
2.
Remove
the
insulation
from
the
ends
of
the
wire
leads by
about
7-
1 0
mm
{9/32"-
13/32").

NOTES:
•
If
length
of
the
exposed wire
is
too
short, a
poor
connection may occur causing operation failure
or
sound
interruption.
• On
the
other
hand,
if
the
length
is
too
long, an
electrical short-circuit may occur.
3.
Tighten
the
set screw
with
the
hexagon wrench
(included)
to
secure
the
lead. (Fig.
8)
Before making this connection, use insulated
shrink
tubing
to
cover any exposed wire
extending beyond
the
terminal.

•
Use
only
the
screws included.
Fig. 8
• For safety reasons, connect
the
battery leads last.
•
To
prevent disconnection
of
the
leads
or
dropping
of
the
unit,
do
not
use
the
cabling
to
carry
the
unit.
