• Interference: The selected location should be far enough away from
devices that may cause interference, such as motors and generators
(see the EMC guidelines earlier in this section).
• Power Source: The unit should be located near a DC power source.
The power cable supplied is 1.5m, but a longer cable can be used if
required. Power must be supplied via a 1A quick blow fuse or circuit
breaker. Refer to Section 5.4, Cable Running.
• Interconnections: The unit transmits navigation and waypoint data
on NMEA and, therefore, can be connected to an NMEA
1
compatible
autopilot or compatible instrument repeater(s). The navigation data
transmitted by the chartplotter is detailed in Appendix C to this hand-
book.
• Environment: The unit should be protected from physical damage,
heat sources and excessive vibration. Although the unit is waterproof,
it is good practice to mount it in a protected area away from prolonged
and direct exposure to rain and/or salt spray.
The dimensions of the unit, including the bracket, are shown in
Figure 5-4.
