Raymarine ST40 - Manual (Page 19)

10 ST40 Speed Instrument Owner’s Handbook
• The equipment is supplied from a different battery from that used for
engine start. Voltage drops below 10 V in the power supply to our
products, 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 at all times. Cutting and
rejoining these cables can compromise EMC performance and so
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 fitted
to Raymarine equipment. Always use the ferrites supplied by
Raymarine.

Connections to Other Equipment
If your Raymarine equipment is going to be connected to other
equipment using a cable not supplied by Raymarine, a suppression
ferrite MUST always be fitted to the cable close to the Raymarine unit.
Tools required
The tools required for fitting the standard ST40 instrument system are
shown in the following illustration.
