Do not turn the power on if the ground wire is not connected. Be sure to install a protective fuse in the power cord near the battery. For the power cord and ground, use a vehicle type (fireproof ) power wring cord with a current capacity greater than the unit's fuse capacity. (Use a power wiring cord with a diameter of 8 mm² (AWG 8) or greater. ) · When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier.
