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.

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.

Locknut	Establishing the ground
	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

123connecting 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 ().

Optional equipment

POWER connector

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.
