Wiring Among Units
• The figure on the next page shows wiring among units.
• The signal cables are fitted with connectors. Connect the cables to the display,
transceiver and hull units referring to the interconnection diagram and the drawing
on page S-1.
• The power cable should be arranged locally. Use power cable type DPYCYS-2 and
DPYCYS-1.25 (both Japan Industrial Standard cables) or equivalent cables. Attach
supplied power connector as shown below.
• Install the main switch for the sonar where it can be easily accessed. Turn off this
switch when the sonar is not being used, to reduce power consumption and to pres-
ent the transducer from slipping by vibration.
• For AC mains, use two rectifiers RU-1746B, one for the display and transceiver
units and the other for the hull unit.
