Orion 220gx Installation Manual page 29

Power Connections for 220gx, 240gx, 280gx, GS-100 or GS-1000
BATTERY CONNECTIONS. Always connect the power
cable assembly directly to the positive terminal on the
battery.
Do NOT connect to the car fuse panel.
The
240gx, 280gx, GS-100 and GS-1000 are provided with
two fuses. The fuse at the battery is designed to prevent
fire or damage to your car should there be a ground
short. The second fuse protects the amplifier itself.
Do
NOT substitute fuses.
Always replace with fuses of the
same fast blow current rating as those supplied with
your amplifier.
AMPLIFIER ON-OFF SWITCH. You
may connect the remote blue lead to the
power antenna or the deck turn-on con¬
nection or install an on-off switch as
shown here. Hooking the blue lead
directly to 12 volts will not allow the
amplifier to turn off.
AUDIO GROUND. f
Connect the small black £
wire to the deck floating
ground when the deck uses
a floating ground. Refer to —
the discussion on floating
grounds on page 28.

GROUND CONNECTION. The large
black wire with the terminal lug must
be connected to a welded chassis mem¬
ber. Do NOT lengthen the ground wire.
If more than one amplifier is used, do
NOT use the same grounding screw,
but always connect both amplifiers
to the same metal member as close
together as possible. Failure to do this
will introduce ground loops and result
in a noisy system.
