Suppression Ferrites; Connections To Other Equipment - Raymarine DSM30 Installation Manual

• The equipment is supplied from a separate battery from that used for engine
start. Voltage drops below 10 V and starter motor transients can cause the
equipment to reset.
This will not damage the equipment, but may cause the loss of some informa-
tion and 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.
• If a suppression ferrite is attached to a cable, this ferrite should not be
removed. If the ferrite needs to be removed during installation it must be reas-
sembled in the same position.

Suppression Ferrites

The following illustration shows typical cable suppression ferrites used with
Raymarine equipment. Always use the ferrites supplied by Raymarine.

Connections to Other Equipment

If your Raymarine equipment is to be connected to other equipment using a cable
not supplied by Raymarine, a suppression ferrite must always be attached to the
cable that is closest to the Raymarine unit.
