6.8 HSB Series System Connections

Grounding the Chartplotter

It is important that an effective RF ground is connected to the
chartplotter. You must ground the system by connecting the drain wire
(screen) of the Power/NMEA Input cable to the nearest ground point of
the ship's RF ground system.
If you need to extend the wire, the extension wire should be an 8mm
braid or 6.0mm
If your vessel does not have an RF system, connect the drain wire to the
nearest suitable ground point

DC Power Connection

The HSB series display is intended for use on ships' DC power systems
operating in the 10.7 to 32VDC range (12V and 24V systems, not 32V
systems). The connections should be made at a DC power distribution
panel, through an isolation switch or circuit breaker that is fused or trips
at not greater than 10A. Check that all connection terminals are clean.
The DC system should be either:
• Negative grounded, with the negative battery terminal connected to
the ships ground.
• Floating, with neither battery terminal connected to the ships ground.
CAUTION:
If you do not have a breaker in your power circuit, you must fit an
in-line 6.3A quick-blow fuse to the positive (red) lead of the power
cable.
This unit is not intended for use on "positive" ground vessels.
The power cable Earth screen connections must be connected to
the ship's ground.

Power for External Equipment

External equipment cannot be powered from the display's SeaTalk
interface.
It must be powered from the ship's supply or via a SeaTalk bus.
For systems where the ship's power source is 24V only, you may need
to install a 24V to 12V DC converter. This is only necessary if the
products being connected to the display are:
2
(AWG 10) multi-stranded cable.
