Suppression Ferrites; Connections To Other Equipment - Raymarine Raystar 112LP Owner's Handbook Manual

Chapter 2: Installation
•
• 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 information 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 reassembled 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 near to the Raymarine unit.
More than 7 ft (2 m) from the path of a radar beam. A radar beam
can normally be assumed to spread 20 degrees above and below
the radiating element.
