POWER CONNECTIONS
The LMS-350A works from a twelve-volt battery system. For the best
results, attach the power cable directly to the battery. You can attach the
power cable to an accessory or power buss, however you may have
problems with electrical interference. Therefore, it’s safer to go ahead and
attach the power cable directly to the battery. If the cable is too short, splice
#18 gauge wire onto it. The power cable has four wires; red, black, green,
and white. Red is the positive lead, black is negative or ground. Make
certain to attach the in-line fuse holder to the red lead as close to the power
source as possible. For example, if you have to extend the power cable
to the battery or power buss, attach one end of the fuse holder directly to
the battery or power buss. This will protect both the unit and the power
cable in the event of a short. The LMS-350A uses a 3-amp fuse.
IMPORTANT!
Do not use this product without a 3-amp fuse wired into the power cable!
Failure to use a 3-amp fuse will void your warranty.
If you’re installing an optional speed/temperature sensor, read the speed/
temperature sensor's installation manual for mounting instructions. Route
the sensor’s cable to the LMS-350's power cable and plug it into the
connector marked “SPEED/TEMP CABLE”
