Electrical Connections
A connection must be made to a 12 or 24 V DC supply via a circuit breaker
capable of supplying at least 2 amps. Connection should be to the ships
radio battery and be in accordance with GMDSS requirements.
⢠Connections are made directly to the screw terminals on the ICS
NAV5plus mating connector at the rear of the unit using the 1m length
cable provided.
⢠Use cable ties to restrain the wiring, and so prevent it becoming
weakened by vibration. The connecting cables should be restrained by
securing them to the rear of the ICS NAV5plus bracket, or to adjacent
metalwork.
Safety Warning
The ICS NAV5plus has been designed and manufactured to be
completely safe when used in accordance with the instructions
given in this manual. To ensure that the complete installation is
safe, it is essential that a fuse or circuit breaker is installed in the
supply cable as described in the Installation Section of this
manual.
The ICS NAV5plus is supplied with a DC power cable and an in-
line Type âTâ 2.5 amp fuse. It is essential that this fuse is included
in the installation.
To ensure the best possible protection of the ICS NAV5plus from
static electricity or nearby lighting strikes, the pre-fitted green
grounding wire (connected to the safety earth stud) must be
connected to a nearby (hull) electrical grounding point.
