Comments
Some of the cables used by the sonar system require additional explanations and
recommendations.
Cable numbers
Cable numbers that are not used are spares for optional equipment and/or future
expansions.
Project cables
The sonar system is often a part of a project delivery. For such deliveries, specific
project cable drawings are established to show all the main cables, and how the
various products are connected. In such project cable drawings, the sonar system
cables may be identified as
sonar/Cx
.
C1, C2, C3, C4, C5 AC Power cables
Standard commercial AC mains cables are used. Each cable is supplied with the
relevant unit. The typical cable length is between 1,5 and 2 meters. If this is too short
you must use an extension cable (not recommended), mount a new power outlet within
range, or make your own power cable with sufficient length.
C4 : This cable is only required if the DC version of the Processor Unit needs to
operate from AC power.
C6 DC Power cable
The HT20470 Processor Unit is available in two versions. The DC version operates
on +24 VDC while the AC version operates on 100 to 240 VAC. This cable is only
required if the Processor Unit operates from DC power.
C7 DC Power cable
The HT20470 Processor Unit is available in two versions. The DC version operates
on +24 VDC while the AC version operates on 100 to 240 VAC. A power supply is
required if a DC powered unit needs to work from an AC supply. This cable is only
required if the DC version of the Processor Unit needs to operate from AC power.
C8 Ethernet cable
The maximum length of the Ethernet cable is 100 meters. It is very important that
high-quality Ethernet cables are used. Do not make the connection using the existing
local area network (LAN).
We strongly recommend that you install a spare Ethernet cable between the sonar
room and the bridge.
Connect the cable to:
