Nexus 21 NX2 Server User Manual


 
SERVER
2 Installation
The installation includes 6 major steps:
1. Read the installation and operation manual.
2. Plan where to install the transducers, Server and
instruments.
3. Install the transducers, then the Server and
instruments.
4. Run the cables.
5. Take a break and admire your installation.
6. Learn the functions and calibrate your system.
Before you begin drilling ... think about how you can make
the installation as neat and simple as your boat will allow. Plan
where to position the transducers, Server and instruments.
Think about leaving space for additional instruments in the
future.
A few ”do nots” you should consider:
- Do not cut the cables too short. Allow extra cable length at
the Server so it can be disconnected for inspection
without having to disconnect all attached cables.
- Do not place sealant behind the display. The instrument
gasket eliminates the need for sealant.
- Do not run cables in the bilge, where water can appear.
- Do not run cables close to fluorescent light sources, engine
or radio transmitting equipment to avoid electrical
disturbances.
- Do not rush, take your time. A neat installation is easy to do.
The following material is needed:
Wire cutters and strippers
Small and large philips and small flat head screw driver
Hole saw for the instrument clearance hole 63 mm (2½")
2.8 mm (0.11") drill for the mounting holes
Plastic cable ties
If the cable is not long enough, you can buy the optional Nexus 8
m (26 ft) extension cable ( Art. No.21266-8 ), or use left over
Nexus cable from other installations. The same 4-pole Nexus
cable is used for all connections.
If you are doubtful about the installation, obtain the services of an
experienced technician.
