Power Connections - Sony XM-4ES Bedienungsanleitung

Connection
• Before making any connections, disconnect the
ground (earth) terminal of the car battery to avoid
short circuits. Connect this amplifier to the +12 V
power supply lead only after all other leads have
been connected.
• This amplifier is designed for negative ground
(earth) 12 V DC operation only.
• Do not operate the amplifier on a weak battery as
the amplifier requires a good power supply for
optimum performance.
• If your car is equipped with a computer system for
purposes such as navigation, disconnecting the
ground (earth) terminal of the car battery may
damage the computer memory. Leave the ground
(earth) lead connected and connect this amplifier
to the +12 V power supply lead only after all other
leads have been connected to prevent short
circuits.
• When connecting and installing the input and
output cables, keep them away from the +12 V
power supply lead. Running them close together
may generate interference noise.
Notes on making connections
• To connect to the terminals on the connector
panel and to adjust various settings, remove the
top cover to access the control panel (top panel).
• When you tighten the screw, be careful not to
apply too much torque as doing so may damage
the terminals or cables.

Power Connections

*1 If you have the factory original or some other car audio
unit without a remote output for the amplifier, connect
the remote input (REMOTE) terminal to the ACC power
supply. In high level input connection, the amplifier can
also be activated without a need for REMOTE connection.
However, this function is not guaranteed for all car audio
units.
*2 Ground (earth) to the car chassis.

+12 V terminal
• Connect the +12 V power supply lead to the +12 V
terminal only after all the other connections have
been completed.
• Use a +12 V power supply lead with a 80 A fuse
attached.
• During full-power operation, a current of more
than 80 A will run through the system. Therefore,
make sure the leads to be connected to the +12 V
terminal are at least 4-Gauge (AWG-4) or have a
sectional area of more than 22.0 mm² (
• All power leads connected to the positive battery
post should be fused within 450 mm (17
the battery post before they pass through any
metal.
• Make sure the leads connecting from the car
battery to the metal point on the car chassis are at
least of a lead gauge equal to that of the +12 V
power supply lead connected from the battery to
the amplifier.
• Make sure the leads connecting from the car
battery to the metal point on the car chassis are
not more than 0-Gauge (AWG-1/0) or have a
sectional area of 55 mm² (2
of a lead gauge equal to that of the +12 V power
supply lead connected from the battery to the
amplifier.
