Connect the LS-4100 power/data cable 
assy MJ-A7SPF0005-020 (2 m, 
supplied) to the POWER, and the 
transducer cable to the XDR connector. 
Refer to the interconnection diagram to 
connect cables. Leave slack in cables to 
facilitate checking and maintenance. 

 
Note: The fuse holder contains a spring 
which fixes the fuse. To prevent 
detachment of the spring, which would 
cause loss of power, tie the line as 
shown below.

The ground wire (1.25 sq or more, local 
supply) should be as short as possible.   
 
The signal line ground is isolated from 
the chassis ground, however the power 
line is not insulated. Therefore, when 
connecting eternal equipment having 
positive ground, do not ground the 
signal line to the chassis. If excessive 
noise shows on the screen, the ground 
may be inadequate. In this case, attach 
a steel plate measuring 20 cm by 30 cm 
on the outside of the hull to provide a 
ground point. Connect the ground wire 
there. Use a “closed” type lug (

) to 

make the connection at the display unit. 
Do not use an “open” type lug (

). 

 

The power supply port is commonly 
used for connection of external 
equipment such as a GPS receiver or 
wind indicator. Use the power/data 
cable MJ-A7SPF0005-020 (supplied) for 
connection referring the figure shown in 
the right column.
