■
Ground connection
To prevent electrical shocks and other problems, ground the display unit through the [GND] terminal. For best
results, connect a heavy gauge wire or strap to the nearest grounding point on the vessel . The distance between
the [GND] terminal and the ground point should be as short as possible.
■
Power source requirement
D
DC power source
The display unit is designed for connection to
any power source with a voltage of 10.2–42 V
DC, so that a 12, 24, or 32 V DC battery can be
used without a DC-DC converter or any internal
modifications.
• DC power cable connection
Connect the supplied DC power cable as shown in
the diagram.
