External Speakerconnections - Raymarine Apelco 5200 User Manual

In most cases, the length of the supplied cable should be adequate 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 line loss. Fig 2-5 provides recommended wire sizes to use for
various cable run distances.
VOLTAGE
Your VHF radio should be connected to the nearest primary source of ship's DC power. A
typical source may be a circuit breaker on the power panel or a fuse block located near the
unit. When connecting to either of these sources, the circuit breaker or other in-line fuse
should be rated at 10 amps.
It is recommended that terminal lugs be used to connect the power cable to the DC supply and
that the lugs should be both crimped and
adequate current draw to the equipment. Intermittent operation may result if an inadequate
connection is made to the power source. The connection terminals should be clean and with
no sign of corrosion.
The RED (+) wire is connected to the positive terminal of the power source or battery. The
BLACK (-) wire is connected to the negative (ground) of the power source or battery. Should
the power polarity be inadvertantly reversed, the 10 amp. in-line fuse located in the RED (+)
conductor will open. Check the input power leads for correct polarity with a VOM, reconnect
the leads observing correct polarity, and replace the fuse. Be sure to use the same rate and
type of fuse.

2.4.2 External SpeakerConnections

The YELLOW (+) wire and GREEN (-) wire are used for connecting the VHF5200 to an exter-
nal speaker. (Refer to Fig. 2-4)
Three 3 watts of audio output power is provided for an external 4 ohm speaker. A suitable
speaker can be purchased from your local marine dealer.
Connect the YELLOW (+) wire and GREEN (-) wire to the speaker observing polarity as it is
marked on the speaker. When connected, the external speaker will function simultaneously
with the internal speaker.
