APX480M Power System Amplifier

INSTALLATION

This section suggests Mounting and Wiring Precautions for installing the Clarion APX480M amplifier. If you do not posses the necessary tools and installation experience, do not attempt to install this amplifier. Instead, con- tact your local Clarion dealer to perform the installation.

MOUNTING PRECAUTIONS

Prior to mounting the amplifier, make sure it is safe to mount the amplifier in that location. Failure to do so can result in serious damage to the boat. In addition, stainless steel hardware should be used to mount the amplifier and additional accessories. When possible, use a nut and bolt with a lock wash- er to secure the amplifier. Extra care and attention is necessary in marine installations due to the uncertainty of water conditions.

Additional precautions and suggestions:

1.For the most efficient cooling, mount the amplifier so cool air runs along the length of the heat sink, rather than across them. To increase air movement and circulation, a cooling fan can be installed.

2.Mount the amplifier on a rigid surface; avoid mounting to subwoofer enclosures or areas prone to vibration.

3.Prior to drilling and holes, make sure the proposed mounting holes will not cut into the fuel tank, fuel lines, electrical wiring, or through the boat.

4.Do not mount the amplifier where it is susceptible to water.

WIRING PRECAUTIONS

Read all of the wiring precautions prior to making any connections. If you are unsure and/or don't have the necessary installation hardware, contact your local Clarion dealer to perform the installation.

1.Before you begin the installation, make sure the source unit Power switch is in the OFF position.

2.Disconnect the negative (-) lead of the battery (or batteries) before making any power connections.

3.When making connections, be sure that each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing. Failure to do so may damage your equipment.

4.A good ground is critical for the performance of the amplifier. A ground wire should be run directly from the battery to the amplifier. Use black insulated 10-gauge or larger wire for the amplifier's ground (-) power lead.

5.Add an additional fuse holder and fuse at the positive (+) terminal of the battery. The fuse rating should equal the total current consumption at full output of the amplifier(s). Use red insulated 10-gauge or larger wire for the amplifier's positive (+) power lead. Do not install the fuse until the complete installation has been performed.
