3.1 General cabling guidanceCable types and lengthIt is important to use cables of the appropriate type and length• Unless otherwise stated use only standard cables of thecorrect type, supplied by Raymarine.• Ensure that any non-Raymarine cables are of the correctquality and gauge. For example, longer power cable runs mayrequire larger wire gauges to minimize voltage drop along therun.Routing cablesCables must be routed correctly, to maximize performance andprolong cable life.• Do NOT bend cables excessively. Wherever possible, ensurea minimum bend diameter of 200 mm (8 in) / minimum bendradius of 100 mm (4 in).100 mm (4 in)200 mm (8 in)• Protect all cables from physical damage and exposure to heat.Use trunking or conduit where possible. Do NOT run cablesthrough bilges or doorways, or close to moving or hot objects.• Secure cables in place using tie-wraps or lacing twine. Coilany extra cable and tie it out of the way.• Where a cable passes through an exposed bulkhead ordeckhead, use a suitable watertight feed-through.• Do NOT run cables near to engines or fluorescent lights.Always route data cables as far away as possible from:• other equipment and cables,• high current carrying ac and dc power lines,• antennae.Strain reliefEnsure adequate strain relief is provided. Protect connectorsfrom strain and ensure they will not pull out under extreme seaconditions.Circuit isolationAppropriate circuit isolation is required for installations usingboth AC and DC current:• Always use isolating transformers or a separate power-inverterto run PC’s, processors, displays and other sensitive electronicinstruments or devices.• Always use an isolating transformer with Weather FAX audiocables.• Always use an isolated power supply when using a 3rd partyaudio amplifier.• Always use an RS232/NMEA converter with optical isolationon the signal lines.• Always make sure that PC’s or other sensitive electronicdevices have a dedicated power circuit.Cable shieldingEnsure that all data cables are properly shielded that thecable shielding is intact (e.g. hasn’t been scraped off by beingsqueezed through a tight area).3.2 Power connection — EV-2The power for the EV-2 unit is provided by the SeaTalkng system.• The EV-2 unit must be connected to a SeaTalkng backbone.This is typically achieved using a SeaTalkng 5-way connectorblock or T-piece connector.• The SeaTalkng system requires only ONE 12 V power source.This can be provided by a battery. If your vessel has a 24 Vsupply a suitable voltage convertor is required.• The power source must be protected by a 5 A fuse or a circuitbreaker providing equivalent protection.• SeaTalkng cables carry both data and power signals. Thepower is supplied to the EV-2 via a SeaTalkng spur cable.• Refer to the SeaTalkng reference manual for more informationon general SeaTalkng power requirements.Power connection — Volvo Penta EVCinterfaceThe EVC interface unit requires a 12 V power source, whichmust be provided to the EVC unit via a battery.• If your vessel has a 24 V supply a suitable voltage convertoris required.• The power source must be protected by a 5 A fuse or a circuitbreaker providing equivalent protection.• The EVC interface unit must be connected to the 12 V powersource via a SeaTalkng 5-way connector block.• A SeaTalkng to bare ends power cable must be used toconnect the SeaTalkng 5-way connector block to the 12 Vpower source.• The supplied DeviceNet to SeaTalkng adaptor cable must beused to connect the EVC interface unit to the SeaTalkng 5-wayconnector block. This cable carries both data and powersignals to the EVC unit.20 Evolution EV-2
