2.2 Positioning the ST70 instrument
CAUTION: Instruments must be placed a safe distance from equipment
that could adversely effect their performance. Refer to the EMC
guidelines on
page v
.
• There must be sufficient space to mount the instrument.
• The connection point should be within 400mm of the install location (unless you
are using an extension cable). In a SeaTalk
ng
network, the connection point will be
a T-piece or connector block on the backbone cable, or another ST70 instrument;
on SeaTalk, the connection point will be an existing instrument, or a connector
block on the system.
• Any holes cut to mount the instrument must not compromise the vessel’s struc-
ture.
