Connecting to the Switchbox
CAUTION
: Be sure to orient the terminal block correctly before
beginning, so the colored wires are connected to the appropriate
terminals and not in reverse order.
NOTE
: For wiring ease, make connections to the terminals
outside of the switchbox.
NOTE
: For Echosounder wire colors, see page 4.
NOTE
: To wire an optional temperature sensor, see page 4
“Connecting an Optional Temperature Sensor” before proceeding.
Wire each cable to its
designated
terminal block (see Table below
and Figure 4).
1. Begin by wiring the single echosounder/transducer. Select a
seven-terminal block. Be sure to orient it correctly as it fits on the
receptor one way only (see Figure 5). Follow the color code on
the printed circuit board labeled Common (J1). Insert the

stripped end of a colored wire into the appropriate square hole
in the terminal.
2. Using a small blade screwdriver, tighten the terminal screw to
lock the wire into place. Be sure the stripped end of the wire is
inserted up to the insulation only.
Do not include any insulation
inside the terminal.
Gently tug on the wire to ensure it is firmly
held in place.
3. Repeat this process until all the colored wires are connected to
the terminal block.
4. Join the terminal block to the appropriate receptor on the PC
board. The block fits one way only. Push the side with the round
holes onto the pins until you hear a snap.
5. Select another terminal block and repeat steps 2 through 5. When
all the cables are connected to their designated terminal blocks, go
to “Closing & Mounting” on page 4.
