Pioneer KEH-P4023R - Manual (Page 3)

Note:
• This unit is for vehicles with a 12-volt battery
and negative grounding. Before installing it in a
recreational vehicle, truck, or bus, check the bat-
tery voltage.
• To avoid shorts in the electrical system, be sure
to disconnect the ≠ battery cable before begin-
ning installation.
• Refer to the owner’s manual for details on con-
necting the power amp and other units, then
make connections correctly.
• Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around them where they lie against metal parts.
• Route and secure all wiring so it cannot touch
any moving parts, such as the gear shift, hand-
brake and seat rails. Do not route wiring in
places that get hot, such as near the heater outlet.
If the insulation of the wiring melts or gets torn,
there is a danger of the wiring short-circuiting to
the vehicle body.
• Don’t pass the yellow lead through a hole into
the engine compartment to connect to the battery.
This will damage the lead insulation and cause a
very dangerous short.
• Do not shorten any leads. If you do, the protec-
tion circuit may fail to work when it should.
• Never feed power to other equipment by cutting
the insulation of the power supply lead of the
unit and tapping into the lead. The current capac-
ity of the lead will be exceeded, causing over-
heating.
• When replacing fuse, be sure to use only fuse of
the rating prescribed on this product.
• Since a unique BPTL circuit is employed, never
wire so the speaker leads are directly grounded
or the left and right ≠ speaker leads are com-
mon.
• Speakers connected to this unit must be high-
power types with minimum rating of 50 W and
impedance of 4 to 8 ohms. Connecting speakers
with output and/or impedance values other than
those noted here may result in the speakers
catching fire, emitting smoke or becoming dam-
aged.
• When this product’s source is switched ON, a
control signal is output through the blue/white
lead. Connect to an external power amp’s system
remote control or the car’s Auto-antenna relay
control terminal (max. 300 mA 12 V DC). If the
car features a glass antenna, connect to the anten-
na booster power supply terminal.
• When an external power amp is being used with
this system, be sure not to connect the blue/white
lead to the amp’s power terminal. Likewise, do
not connect the blue/white lead to the power ter-
minal of the auto-antenna. Such connection could
cause excessive current drain and malfunction.
• To avoid short-circuiting, cover the disconnected
lead with insulating tape. Especially, insulate the
unused speaker leads without fail. There is a pos-
sibility of short-circuiting if the leads are not
insulated.
• To prevent incorrect connection, the input side of
the IP-BUS connector is blue, and the output side
is black. Connect the connectors of the same col-
ors correctly.
• If this unit is installed in a vehicle that does not
have an ACC (accessory) position on the ignition
switch, the red lead of the unit should be con-
nected to a terminal coupled with ignition switch
ON/OFF operations. If this is not done, the vehi-
cle battery may be drained when you are away
from the vehicle for several hours.
• The black lead is ground. Please ground this lead
separately from the ground of high-current prod-
ucts such as power amps.
If you ground the products together and the
ground becomes detached, there is a risk of dam-
age to the products or fire.
