POWER CONNECTIONS
The X-70A 3D works from a twelve-volt battery system. For the best re-
sults, attach the power cable directly to the battery. You can attach the
power cable to an accessory or power buss, however you may have prob-
lems with electrical interference. Therefore, it’s safer to go ahead and
attach the power cable directly to the battery. If the cable isn’t long enough
to reach the battery, splice #18 gauge wire onto it. The power cable has
two wires, which are red and black. Red is the positive lead, black is nega-
tive 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 a short occurs.
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’ve purchased the optional ST-T speed/temperature sensor, install it
according to the instructions included with the sensor. Route its cable to
the X-70A 3D’s power cable and plug it into the connector marked “SPEED/
TEMP CABLE”.
