ALS-500M

1. The negative battery lead must be disconnected from the battery post.

2. The positive battery terminal must be disconnected from the positive battery post.

3. Add a heavy ground strap from the engine block or the battery's negative lead to the chassis of the

vehicle.

4. The long heavy black ground lead on the amplifier power plug should be connected to battery's

negative ground cable terminal. Please note this cable is slightly longer than optimum for the 10

gauge wire supplied.

5. Connect the short black ground lead from the amplifier power plug directly to the vehicle's

chassis.

6. Both of the heavy red positive high current leads must be fused at the battery with two 30

ampere fuses. Each lead will carry 40 amperes peak (20 amperes average) during normal operation

of the amplifier. Two 30 ampere spade type fuses, PN 755-1730, fit into fuse holders supplied with

this amplifier. See page 5 for fuse holder installation instructions. Please note this cable is slightly

longer than optimum for the 10 gauge wire supplied.

7. The red low current power lead must connect to the positive battery supply through a 5 ampere

fuse, PN 755-1405. This lead will reset a LOAD FAULT condition if power is momentarily

interrupted and restored. This lead can also provide a remote operate - standby function. This can

be accomplished by connecting a remote switch in series with this lead. Connecting this lead to a

permanent voltage source without a series off-on switch will result in a battery drain of a few

milliamperes if the amplifier's POWER switch is accidentally left "ON". This lead should be

connected to a manually switched electrical system lead for controlling the off-on function, an

ignition key switched power source, or through a combination of the two.

8. Connect the RF output (antenna) of the exciter to the RF IN (SO-239) of the ALS-500M with a

good quality 50 ohm cable capable of handling 100 watts.

9. Connect the vehicle's antenna system to the RF OUT (SO-239) connector with 50 ohm coax that

will safely carry 600 watts. This is where the RF output meter or antenna connects.

10. Use a shielded audio type cable with standard male phono (RCA) connectors to connect the RLY

jack of the ALS-500M to the transceiver or transmitter normally open amplifier relay terminal.

This connection has 12 volts open circuit and supplies less than 100 mA of current when pulled to

ground. There is a back pulse canceling diode in the amplifier for exciter protection.

11. Plug the female multi-pin power connector onto the multi-pin male connector on the rear of the

ALS-500M chassis.

12. Reconnect the positive and negative battery leads to the battery.
