3.4 Connect power
3.4.1 Power source
• If you are connecting additional NMEA2000 equipment other than
SAILOR 6194 or SAILOR 6018 to the CAN bus, the power source for the
mini-C system must supply 15 VDC (nominal). To convert to 15 VDC
you may use e.g. a SAILOR 6090 Power Converter or a SAILOR 6081
PSU and Charger.
• The power source must be able to deliver sufficient power for the
system units. Refer to Power requirements on page 12.
3.4.2 Connect the power cables
3.4.2.1 SAILOR 3027
The SAILOR 3027 has one CAN connector, which is also used for power
input.
1. Connect the red wire to DC+ and the black wire to DC- in the power
supply.
2. Connect the shield of the CAN cable to chassis on the power supply,
which must be connected to ship ground. See Ground the units on
page 29.
Note If your power source is supplying more than 15 V, the system
is not protected against incorrect wiring.
Caution!
If your power source is a battery, you must configure an
under-voltage protection for the battery. The battery
may be damaged if the correct under-voltage protection
is not applied! For details, see
Under-voltage protection
(UVP) on page 34.
