2.1 EMC Installation Guidelines
Althoughevery efforthas been takento ensure that ourproducts will
performunder all conditions, it isimportant to understand what
factorscould affect the operation ofthe product.
Theguidelines given heredescribe the conditionsfor optimum EMC
performance,but it is recognized thatit may not be possible tomeet
all of these conditionsin all situations. To ensurethe best possible
conditionsfor EMC performance within the constraints imposed by
any location, always ensure the maximum separationpossible
between different itemsof electrical equipment.
For optimum EMC performance, it is recommended that wherever
possible:
• Raymarine equipment and cables connected to it are:
• At least 3 ft (1 m) from any equipment transmitting orcables
carrying radio signals e.g. VHF radios, cables and antennas.
In the case of SSB radios,the distance should be increasedto
7ft(2m).
• More than 7 ft (2 m) fromthe path ofa radar beam. A radar
beam can normally be assumed to spread 20degrees above
and below the radiating element.
• The equipment is suppliedfrom a separatebattery from thatused
for engine start.Voltagedropsbelow10 V,and starter motor tran-
sients, can causethe equipment toreset. This willnot damage the
equipment, but may cause the loss of some informationand may
change the operating mode.
• Raymarine specified cables are used. Cutting and rejoining these
cables can compromise EMC performance and must be avoided
unless doing so is detailed in the installation manual.
