INSTALLATION MANUAL OF OF N STAR N STAR INSTALLATION MANUAL GEX-FM903XM This product conforms to CEMA cord colors. Connecting the Units Note: • This unit is for vehicles with a 12-volt battery and negative grounding. Before installing it in a recreational vehicle, truck, or bus, check the battery voltage. • To avoid shorts in the electrical system, be sure to disconnect the ≠ battery cable before beginning installation. • Refer to the owner's manual for details on connecting the power amp and other units, then make connections correctly. • Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap adhesive tape around them where they lie against metal parts. • Route and secure all wiring so it cannot touch any moving parts, such as the gear shift, handbrake and seat rails. Do not route wiring in places that get hot, such as near the heater outlet. If the insulation of the wiring melts or gets torn, there is a danger of the wiring short-circuiting to the vehicle body. • Don't pass the yellow lead through a hole into the engine compartment to connect to the battery. This will damage the lead insulation and cause a very dangerous short. • Do not shorten any leads. If you do, the protection circuit may fail to work when it should. • Never feed power to other equipment by cutting the insulation of the power supply lead of the unit and tapping into the lead. The current capacity of the lead will be exceeded, causing overheating. • When replacing fuse, be sure to use only fuse of the rating prescribed on the fuse holder. • To prevent incorrect connection, the input side of the IP-BUS connector is blue, and the output side is black. Connect the connectors of the same colors correctly. • If this unit is installed in a vehicle that does not have an ACC (accessory) position on the ignition switch, the red lead of the unit should be connected to a terminal coupled with ignition switch ON/OFF operations. If this is not done, the vehicle battery may be drained when you are away from the vehicle for several hours.
