[. . . ] The positive line should be protected by a circuit breaker, 10 A recommended. In addition, each cluster of instruments requires a fuse in the positive power supply. NAVMAN junction boxes have the required fuses built in, otherwise fit 1 A fuses.

The warranty does not cover damage caused by moisture or water entering the junction box. Ensure that any holes that you cut will not weaken the boat's structure. If in doubt, consult a qualified boat builder. 4-1 Position When fitting the NavBus junction box ensure that there is sufficient space under the overhang to allow for removal of cover. Important: Minimum clearance under overhang edge 67 mm (2 5/8") Always orient the NavBus junction box so the lugs are pointing down. 5 NAVMAN NavBus Installation and Operation Manual 4-2 NavBus junction box The NavBus junction box simplifies wiring systems of instruments. The box has one four-way terminal block for attaching power and data cables and four seven-way terminal blocks for attaching power/data cables from colour coded NAVMAN instruments. When fitting a NavBus junction box: Orient the box so that the cable tie lugs point down. Match the wire colours to the colours of the terminal block terminals. Note: Minimum clearance under overhang edge 67 mm (2 5/8") NavBus junction box Fuse, 1 A typical Mounting screw Jumper Schematic Fuse, 1 A typical Jumper Red Black Orange Blue Green Yellow White Note: refer to Appendix A for colour coding Lugs to hold cable ties 4-3 Fitting the cover The NavBus junction box cover slides from the top into place. NAVMAN NavBus Installation and Operation Manual 6 4-4 Junction box power and NavBus data wiring Power wiring can be simplified by wiring power to the junction box, each instrument is powered from the NavBus junction box(es). System with one junction box No external NavBus data cable is required. Junction box Red Black Orange Blue Green Yellow White Power cable Boat's instrument power switch Red 12 V DC power Black System with more than one junction box The power and NavBus data cables can be connected together in a star, daisy-chain or any combination of the two. The maximum total length of NavBus data cable in a system is 100 m (330 ft).

It is only necessary to connect the external beepers or lights to a green terminal in one junction box. Red External beepers or lights Here, two sets of external beepers or lights are connected. Green DEPTH 3100 DEPTH 3100 Red External beepers or lights Green DEPTH 3100 Red External beepers or lights Green DEPTH 3100 Important: Ensure wires are stripped and tinned. 4-6 Junction box instrument wiring SPEED 3100, DEPTH 3100, MULTI 3100 or WIND 3100 Wire the instrument's power/data cable to one of the seven-way terminal blocks in the junction box. Wire any REPEAT 3100s to the end terminal block (see next page), otherwise ensure the jumper is fitted in the junction box. (See section 4-2) Wire any NMEA inputs or outputs required for the instrument to the yellow or white terminals. For example, in the diagram below right, there is a DEPTH 3100 and a MULTI 3100, which both have depth transducer inputs. In some circumstances no transducer is required, refer to each instrument's Installation and Operation manual.
