Electrical Connections

The G2 Distribution Unit contains five (5) terminal blocks to connect signals from:

• Ship Power,

• Vector G2,

• Display Heads, and

• external NMEA devices.

Figure 5 shows the location of each block in a distribution unit.

Connector Termination

The terminal blocks in the Distribution Unit allow all wiring from the GPS Compass, Display

Head(s) and external devices to be conveniently and reliably terminated. Figure 6 and Figure

7 illustrate the proper termination procedure. To properly terminate a wire in the terminal

blocks:

• Insert a narrow slotted screw driver into the opening above the terminal clamp

• Twist the screwdriver Up to open the terminal clamp

• Insert the wire all the way into the terminal clamp

• Release and remove the screwdriver

• Pull the wire to ensure the terminal clamp has securely gripped the wire.

It is easiest to connect wires on the lower tier before wires on the upper tier. This way the

upper tier wires will not obstruct the terminal clamp for the lower tier.
