B&G equipment is designed to be operated in leisure craft. Every care has been taken in its design and
testing to ensure compliance with the European EMC Directive, provided it is installed and operated in
accordance with the instructions as supplied, and the units and cables used are unmodified. Specific
attention is drawn to the requirements to maintain cable separation, where stated.
Transmissions from poorly installed or maintained Single Sideband equipment may adversely affect the
functioning of this equipment. On vessels fitted with SSB, it is essential that such equipment is
installed following good installation practice and as recommended by the manufacturer.
general wiring notes
x Do not apply power to the pilot system until all units are connected and the wiring has been
checked.
x Where spade connectors are supplied, always use the correct crimping tool to attach them to the
cable. This is extremely important where high currents are to be passed; i.e. rudder drive unit
supply cables.
x Keep supply cables as short as possible to reduce the possibility of a voltage drop in the cables.
x Always fit a fuse or circuit breaker in supply cables. It is recommended that heavy-duty power
cables are protected by a 25A MCB.
x Clearly identify each cable to prevent incorrect connection.
x Cables that have a screening braid must have the screen connected as shown on the connection
diagrams.
x All Pilot cables should be routed at least 1m (3ft) from cables or components that carry or
generate high currents; e.g. alternators, starter motors, trim-tab cables, etc.
x To minimise interference avoid routing Pilot cables alongside high power radio or radar cables.
x To prevent damage to cabling always secure in position using cable clips or tie-wraps. Where
cables pass through bulkheads always protect the cable from chafing by fitting grommets.
x Do not allow cables to rest in the bilges where prolonged immersion in water, fuel, etc. may
occur.
x Always fit splash covers and lids on processors, computer units and junctions boxes, where
supplied.
