Power Connection; Sensor Connection - JRC JFC-7050 Operation Manual

Installation
Drill a 1/4 in. diameter hole at each marked location. Mount the Display unit bracket using bolts
through the mounting surface. Place large flat washers on the opposite side of the mounting surface
from the bracket and then install lock washers and nuts. Tighten securely.
Install the display unit into the mounting bracket. Check alignment and operation of the pivots and
security of the mounting. Make any adjustments necessary to prevent binding and assure even
meshing of the pivot locking washers. It is advised to remove the display unit and store it in a safe
place to prevent damage during the rest of the installation process.

Power Connection

Power is supplied to the Echo sounder Unit through a connector on the rear panel of the display unit.
Route the power cable from the Echo sounder Unit location to the ship's power distribution panel.
Connect the black wire to a battery negative (-) terminal of the power panel.
Connect the white wire to a fused battery positive (+) terminal of the power panel ( 12 to 24 Vdc
nominal). If a fused terminal is not available, install an in-line fuse holder.

Sensor Connection

There are many sensors and transducers available which may be used to expand the capabilities of
the Echo sounder Unit. Connectors for these accessories are provided on the rear panel of the Echo
sounder Unit. For most sensors, only data and control connections are routed to the Echo sounder
Unit.
