2.3 Power Connections

The red and black Power Cord provides connection to DC power. The red (+) wire contains a 7 amp in-line fuse. It should be connected to the positive terminal of the power source. The black (-) wire should be connected to the negative (ground) of the power source. Check the polarity with a VOM (Voltage/Ohm Meter) and reconnect observing correct polarity. If the fuse ever needs to be replaced, be sure to use the same type and rating.

Connect the stripped wires on the Power Cord to the nearest primary source of the boat's DC power. A typical source would be a circuit breaker on the power panel or a fuse block near the unit. The circuit breaker or other in-line fuse should be rated at 10 amps. The power cord should be long enough to reach the DC power source. If additional wire length is required, the cable can be extended by adding more cable as necessary. However, for power cable runs longer than 15 feet, larger wire diameter size should be used to prevent voltage line loss. To ensure adequate current draw to the equipment, Raymarine recommends that you use lugs to connect the power cable to the DC supply and that the lug connections be both crimped and soldered. The connection terminal should be clean, with no sign of corrosion.

After the cord is connected to power, slide the bullet connectors on the Power Cord into their mates (with the same colored wire) on the rear of the radio. (See Figure 2-3 .)

The Ray54 is designed to be operated on a 12 volt (nominal) system. If battery voltage drops below 10.5 VDC (approximately), the icon appears on the LCD (see page 15). Discontinue using the radio if a low voltage condition occurs as performance would be unreliable. If voltage exceeds 16 VDC, the message EXCESSIVE VOLTAGE appears on the dot matrix display and an alarm is sounded. Immediately disconnect the radio if a high voltage condition occurs as the unit could become damaged.
