The SVS-650 is provided with a 6-foot power & data cable as standard equipment. Connect the
power leads directly to the main battery isolation switch or breaker, or route the power leads to the DC
power distribution panel. At the power source, connect the red wire to the positive terminal (+), and
the black wire to the negative terminal (-).
(NOTE: the SVS-650 is internally protected if you accidentally reverse the polarity of the power wires.)

To prevent any interference or electrical noise, separate the SVS-650 power wiring as much as
possible from other devices.

If you need to extend the power wiring by more than 10 feet, use a larger wire size. This will
allow the wires to deliver the correct voltage in spite of the longer wire distance. For runs of 20 to 35
feet, use #14/2 AWG wire. If you need to extend the power wiring, be sure all electrical connections
are solid and durable. Insulate all connections using heat-shrink tubing or high quality electrical tape.
You may use crimp connectors or a terminal strip, but be sure to use good-quality marine-grade parts.

When you press the Power button, the display unit should turn on. If the unit will not turn on and
you suspect that you may have reversed the power connections, check the DC power lines all the way
back to the battery. If the polarity is not correct, reconnect the leads properly and try again.
